S8 E3: Postcards from Lake Superior: How Letteracy Deck Inspires Letters, Stories & Connection — with Anne Brataas
Season 8, Episode 3
Show notes
On the Lake Superior shoreline in Grand Marais, Minnesota, there is a place where visitors are invited to put down their phones, pick up a pen, and send a letter—postage included. Letteracy Deck, created by Minnesota Children’s Press, is a free, screen-free letter-writing park that has helped visitors send more than 17,000 cards and letters since opening in 2023.
In this episode of the Lake Superior Podcast, Walt Lindala and Frida Waara talk with Anne Brataas of Minnesota Children’s Press about how handwritten letters, storytelling, and creative literacy can connect generations and help children see the value in their own stories. Join us for a conversation about letter writing, creativity, Story Scouts, and what can happen when people trade scrolling for a pen, a postcard, and a little time by the lake.

S8 E2: Exploring Lake Superior’s Deepest Waters: The Mystery of the “Zombie Fish” — with Shawn Sitar
Season 8, Episode 2
Show notes
More than 1,300 feet below the surface of Lake Superior, scientists are investigating a fisheries mystery: siscowet lake trout that should be fat and robust are turning up strikingly thin. Researchers call them “zombie fish,” but the real story is less sensational—and still unresolved.
In this episode of the Lake Superior Podcast, Walt Lindala and Frida Waara talk with returning guest Shawn Sitar, a Michigan DNR fisheries research biologist and science officer aboard the RV Lake Char, about what the team is learning from Lake Superior’s deepest waters. From possible food shortages and disease testing to lake trout recovery and long-term monitoring, Shawn takes us into the science behind one of Lake Superior’s most unusual recent findings and how long-term fisheries research helps scientists track the health of the lake.
Notable quotes:
• “There’s a famine event going on out there…they actually kind of look like zombies.”
• “We’re not alarmed, we’re concerned.”
• “Overall, Lake Superior is in a really good place…We have abundant populations of fish. We have a lot of biodiversity also.”
• “Recently we declared that lean lake trout, the one that’s utilized by humans, has been recovered or in a rehabilitated state. That’s a good sign.”
• “I’m glad to work on a system that is basically the most natural of the Great Lakes. Things are in good shape.”
• “Part of my duty is to communicate the science to everyone so that they have a better understanding and appreciation of everything around us.”Helpful links:

S8 E1: Carrying Big Annie Clemenc’s Story Forward: From the 1913 Copper Strike to Calumet’s New Statue — with Vada Riederich
Season 8, Episode 1
Show notes
More than a century after the 1913–14 Copper Country Strike, one of its most prominent leaders now has a permanent place in downtown Calumet, Michigan. Anna Klobuchar Clemenc, better known as “Big Annie,” was born in Calumet to Slovenian immigrant parents and became a leader in the strike, founding and serving as president of the Women’s Auxiliary No. 15 of the Western Federation of Miners.
In this episode of the Lake Superior Podcast, Walt Lindala and Frida Waara talk with Team Big Annie chairperson Vada Riederich about the years-long community effort to raise $150,000 to create a bronze statue honoring her legacy and the August 2026 unveiling. Vada about how a Facebook post grew into a years-long campaign, the people who helped make the monument possible, and what Big Annie’s legacy can teach new generations about labor history in Michigan’s Keweenaw Peninsula.
Notable Quotes:
• “She was driven and she would not give up on what should be fair and right.”
• “At that time when women had no voice and no vote, that's quite an undertaking for a young woman of 25 years old.”
• “I hope that young people will be inspired to learn more about our amazing history and be proud to share it.”
• “We're still a young nation and we're still growing and learning from our mistakes…history gives you that information so we can figure a path to correct those mistakes”
• “So she spoke up at that time, and it led to good things in the future.”Helpful links:

S7 E12: A New Life for Abandoned Mines: Energy, History and Innovation — with Timothy Scarlett
Season 7, Episode 12
Show notes
For generations, the mines of Michigan's Copper Country have been woven into the history of the Lake Superior region. While many of those mines closed decades ago, their stories — and the underground landscapes they created — continue to leave their mark on the communities above them. Today, researchers are combining archaeology, historic records, and emerging technologies to better understand the region's mining history, improve public safety, and explore how these underground landscapes may serve future generations.
In this episode of the Lake Superior Podcast, Walt Lindala and Frida Waara talk with Tim Scarlett, Associate Professor of Archaeology at Michigan Technological University. They explore the challenges of mapping abandoned mines, why understanding these underground landscapes matters, and what they can teach us about the past and perhaps the future.

S7 E11: Moosewatch, Wilderness Learning and the Lasting Pull of Isle Royale — with Karen Bacula
Season 7, Episode 11
Show notes
Isle Royale is one of the least visited of America’s National Parks. Located in the northwest corner of Lake Superior, it’s a tough place to get to. Access is only by seaplane, ferry or private boat. But once visitors do come, they are likely to return. Karen Bacula has been coming to this remote island since 1997. As a teacher, she also brought students to explore this unique archipelago of islands. Now, retired, she volunteers as director of Michigan Tech’s Isle Royale Institute and coordinates Moosewatch volunteers, helping people take part in fieldwork that supports the world’s longest-running predator-prey study. In this episode of the Lake Superior Podcast, Walt Lindala and Frida Waara talk with Karen about citizen science, wilderness learning and the lasting pull of Isle Royale.
Quotes:
• “What connected me and made me want to just keep coming back was the beauty, the quiet, the simplicity, but yet incredibly complex whole area of what was there being surrounded by the lake. And many of the people I met were just absolutely wonderful.”
• “The power of the island, the power of the lake, the serenity, but also realizing that at the drop of a hat, the weather can change. So there's predictability and uncertainty in every step that you take. And I like that feeling.”
• “There's something special and new about it each time and getting to see the changes.”
• “We’re looking for dead moose and looking for the condition of the skeleton to see what the moose age-wise, health-wise was like, potentially how it died.”
• “It becomes very cross-curricular at all different grade levels. But they all come out with the big excitement being to learn how the study's done and to learn the field techniques for collecting data for this study.”
• “Two things I tell them to pack that are not necessarily on the gear list is their patience and sense of humor.”
• “Work to bring some of what you just felt right now with the people you met and living as close to the earth as you can live, bring some of that back with you and hold on to that.”Helpful links:

S7 E10: From Rare Sight to Remarkable Recovery: Bald Eagles and the National Eagle Center — with Ed Hahn
Season 7, Episode 10
Show notes
The bald eagle has been the patriotic symbol of America for 250 years. Most folks can remember the first time they saw this majestic bird soaring in the wild. There was a time when sighting them, even on Lake Superior, was rare, but today these birds of prey are making a comeback. Their return represents one of America’s most visible conservation successes. In this episode of the Lake Superior Podcast, Walt Lindala and Frida Waara talk with Ed Hahn, Director of Advancement and Marketing Communications at the National Eagle Center in Wabasha, Minnesota, about the bald eagle’s recovery, how to recognize young eagles and what visitors can learn by meeting an eagle ambassador face to face.
Quotes
• Ed Hahn says the species has made "a complete and total recovery" and calls that "a truly incredible accomplishment for Americans to take some pride in," adding, "We accomplished that through public action."
• “But just like everyone else, we truly do wish that they could be living their full lives as intended as wild eagles out in the wild.”
• “We have to work with them to educate the public and we have to be sharing those birds with the public.”
• “Bald eagles are covered in approximately 7,000 feathers.”
• “There's always new things to learn about eagles.”Helpful Links

S7 E7: The Future of Moose in Minnesota: What a New Study of Young Moose Could Reveal — with Michelle Carstensen
Season 7, Episode 7
Show notes
No mammal represents Minnesota’s north shore better than the moose. The winter of 2026 has been busy and significant for these majestic animals. Through the Northern Moose Alliance (http://www.moosealliance.org/), a joint effort between Minnesota Department of Natural Resources, 1854 Treaty Authority, Grand Portage Band of Lake Superior Chippewa, and the National Parks of Lake Superior Foundation, 60 juvenile moose were collared to launch a study on why the moose population has seen a 60% decline in recent years. In this episode of the Lake Superior Podcast, Walt Lindala and Frida Waara talk with Michelle Carstensen, Wildlife Health Group Leader for the Minnesota’s DNR about the project and the partnerships that have come together to better learn about the region’s moose.
We’d love to keep you updated as this work evolves and share ways you can help protect moose as opportunities arise.

Quotes
“It's been a very moose-filled winter for us, which, if you ask me, is a great way to spend the winter.”
“What we want to know is how many can survive over winter and at what age they become reproductively contributing to the population.”
“We were missing that middle cohort of animals, which is a huge driver if you want to have a population that’s going to grow.”
“We’re trying to understand why the moose population has been kind of stagnant.”
“It’s our role as stewards to try to help this population thrive.”

S7 E6: One Lake, Five Parks, Twenty Years: The NPLSF Story — with Carol Brady
Season 7, Episode 6
Show notes
What started on March 1, 1872, when Yellowstone became the first National Park in the world, has grown to over 433 units covering over 85 million acres in America. Tagged "America’s Best Idea," we celebrate National Parks Week every year in April. Roughly 20,000 people work either full-time or seasonally with the National Park Service but the system also relies on over 130,000 volunteers. The National Parks of Lake Superior Foundation--sponsor of this podcast--is one of those volunteer organizations.
In this episode of the Lake Superior Podcast, Walt Lindala and Frida Waara talk with Carol Brady, founding board member and long-time Chairman of NPLSF, about the organization’s mission and projects that have developed over the last two decades.
5 Quotes
• “In 2026, this will be 20 years since we became an actual official 501(c)(3) nonprofit foundation.”
• “National Park Service unbelievably has over 400 units in the country, and the government budget for the National Park Service is a finite number.”
• “There’s only so much budget to go around. In order to keep all of these places as special as folks expect them to be when you go there, they need help. They need outside help.”
• “That is an ongoing thing that will last much longer than I will, I’m quite sure.”
• “You’re not going to really notice that this is not the coast of an ocean. The lake could be calm, it can be just wild, but the best thing is it’s clear and cold. You dip it in there and take a drink, it’s just great. It’s fresh water. It’s just amazing. People think it’s going to just look like a big lake, and then when they realize it looks like the ocean, they forget that it’s clear and cold and fresh.”Connect With Us:

S7 E5: Keweenaw’s Legendary Snowfall: Winter Recreation and Traditions in the Upper Peninsula’s Snow Capital — with Jesse Wiederhold
Season 7, Episode 5
Show notes
While some parts of the country can count on crocus and daffodils to signal spring in March, Michigan’s Keweenaw Peninsula is still measuring snowbanks. Over 300” has fallen across the region and more is expected, possibly into May. From the looks of future forecasts, the area is sure to surpass last year’s total of 315.25” and may be on track for the all-time high of 390.4” set back in the winter of 1978-79. What do you do with over 32’ of snow in a season? In this episode of the Lake Superior Podcast, Walt Lindala and Frida Waara talk with Jesse Wiederhold, Managing Director of Visit Keweenaw, about what makes this area of Michigan’s Upper Peninsula such a mecca for snow lovers and tips on how they survive cabin fever.
5 Key Takeaways
• Extraordinary Snowfall Totals In The Keweenaw Peninsula: Jesse Wiederhold says the Keweenaw had already passed 200 inches of snowfall by early January and notes that the historical snowfall record in Keweenaw County is about 390 inches in a single season recorded in the late 1970s.
• Lake Superior Drives The Region’s Heavy Snowfall: Wiederhold explains that Lake Superior acts as a “snow machine,” producing lake-effect snow because the Keweenaw Peninsula is surrounded by the lake on multiple sides.
• Winter Recreation Draws Visitors To The Keweenaw: Visitors come to the region for winter activities including skiing, snowmobiling, cross-country skiing, snowshoeing, and snow biking, with ski areas such as Mount Ripley and Mount Bohemia operating during the winter season and drawing large numbers of visitors, including days when more than a thousand people ski at Mount Bohemia.
• Groomed Trail Systems Support Winter Sports In The Region: Wiederhold highlights several groomed trail networks located within about a 30-minute radius of Houghton and Hancock, including the Michigan Tech trails in Houghton, the Maasto Hiihto and Churning Rapids trails in Hancock, the Swedetown trails in Calumet, and the East Bluff trails in Copper Harbor.
• Finnish Heritage And Sauna Culture Remain Strong In The Keweenaw: Wiederhold notes that about one in three people in Houghton County are Finnish and explains that sauna culture remains an important part of local life, with both home saunas and public sauna experiences such as those at Mount Bohemia and Taka Saunas available in the region.Helpful Links:

S7 E4: Bat Science and Survival: Lake Superior’s Night Flyers — with Dr. Winifred Frick
Season 7, Episode 4
Show notes
Bats have been called the “Invisible Mammal” primarily because they fly silently and mostly at night. They also roost in dark places, caves or abandoned mines, making them hard to find even in the daylight. For humans, bats aren’t only hard to see, they are hard to understand, yet they play a vital role in our world’s ecosystems and an equally important roll in our agricultural economy. Yet 200 species of bats are nearing extinction. In this episode of the Lake Superior Podcast, Walt Lindala and Frida Waara talk with Winifred Frick, Chief Scientist at Bat Conservation International, to learn more about what is threatening bat populations around Lake Superior.
5 Key Takeaways
Bats Are More Diverse — And Longer-Lived — Than Most People Realize
Winifred Frick notes that bats are “the only mammals that can fly,” and that scientists have “just celebrated the discovery of the 1,500 bat species.” In the U.S. and Canada, she says there are “about 47 different bat species.”
White-Nose Syndrome Has Devastated Bats Around Lake Superior
Frick explains that white-nose syndrome is caused by a fungal pathogen — Pseudogymnoascus destructans (“PD”) — and says it “first emerged…in the winter of 2006, 2007.” She adds that it “has killed millions of bats in its wake” and highlights a “99% decline” in the northern long-eared bat population.
The Fungus Spreads Through Hibernation Sites — Not Just Bat-to-Bat Contact
Frick describes how the fungus grows on bats’ skin (including wings, ears, and muzzle) and can also persist on cave and mine surfaces. She explains bats can pick it up “either by coming in contact with each other” or by contacting “the surfaces where they roost.”
“Fat Bat Project” — A Practical Experiment To Help Bats Survive
Frick explains how white-nose causes bats to burn through fat reserves by arousing too often during hibernation, leading them to “starve to death before spring.” In Michigan’s Upper Peninsula, her team tested using UV lights near mines (including near the Delaware Mine area) to attract insects and boost foraging — what Frick calls “our fat bat project.”
You Can Help Bats By Supporting Habitat, Native Insects, And Conservation Work
Frick points to Bat Conservation International’s “bat gardens program,” encouraging people to plant native plants that support moths and beetles. She also emphasizes advocating for nature protection and supporting organizations funding bat research and conservation actions.

S7 E3: Lake Superior’s Lasting Hold: The Story Behind A Is for Agates: A Lake Superior Alphabet Book — with Patti Baraks
Season 7, Episode 3
Show notes
For some, growing up on Lake Superior carves a deep connection to place, and no matter where life leads, the pull to return to that rugged shoreline never leaves. Patti Baraks knows too well that hold Superior creates. She grew up in Superior, Wisconsin, and although she has lived, worked and raised a family in Texas, she admits, her internal compass always points north toward that mighty lake. As an early childhood education teacher with a passion for poetry, she used that lure to write a children’s book, “A is for Agates, A Lake Superior Alphabet Book”.
In this episode of the Lake Superior Podcast, Walt Lindala and Frida Waara talk with Patti not only about her time in Wisconsin, but also about the motivation and process of producing a children’s book.
If you’d like a copy, or need a perfect Lake Superior–themed Christmas gift, she shares that you can find the book at independent bookstores and libraries around the Lake Superior region. It’s also available online at Itasca Books:
https://itascabooks.com/products/a-is-for-agates-a-lake-superior-alphabet-book-1
Key takeaways
Patti’s Deep Connection to Lake Superior Has Never Faded
Patti Baraks grew up in Superior, Wisconsin, a city she describes as “one of the greatest port cities on Lake Superior.” She explains that Lake Superior shaped every part of daily life — the economy, recreation, and weather — and says the lake “has always had a hold over me that I can’t quite explain.” Even after moving to Texas, she shares that her “internal compass points north” and draws her back every summer.
The Passing of Her Father Motivated Her to Finally Write a Book
Patti says she had “always wanted to be a writer,” but it wasn’t until her father passed away about a year and a half before the interview that she decided she didn’t want “a cloud of regret” about never pursuing that dream. This loss gave her the push to “get out of [her] comfort zone and just go for it.”
Collaboration With Illustrator Lisa Perrin Cosmo Was Central to the Book’s Success
Patti selected illustrator Lisa Perrin Cosmo after seeing an agate painting in her portfolio and feeling immediately drawn to her work. She says Lisa is “local to the North Shore,” “really knows the lake,” and seemed able to “read my mind” when creating the illustrations. Patti calls her artwork “breathtaking” and says the illustrator “paints the best moose.”
Patti Believes Nature-Based Literature Helps Children Explore and Learn
As a former teacher, Patti says that nature-based books encourage kids to get outside, reduce stress, and learn through observation. She describes the outdoors as “the original classroom,” where children discover things independently, ask questions, and engage their natural curiosity.

S7 E1: The Edmund Fitzgerald Story and Legacy: 50 Years Beneath the Waves — with Fred Stonehouse
Season 7, Episode 1
Show notes
The Gales of November is very real on the Great Lakes, known as the “Month of Storms.”
Some 550 wrecks lie on the bottom of Lake Superior, at least 200 along Superior’s Shipwreck Coast, a treacherous 80-Mile stretch with no safe harbor between Munising and Whitefish Point.
On November 10, 1975, the Edmund Fitzgerald, a 728 foot freighter went down in a storm described as both blizzard and hurricane taking all 29 crew members to their grave. Made famous by the Gordon Lightfoot song, the wreck has remained a mystery for fifty years.
In this episode of the Lake Superior Podcast, Walt Lindala and Frida Waara talk with maritime historian, author and lecturer Fred Stonehouse about that tragic night and what we have learned since her sinking and how her legacy has shaped maritime safety.
Key Takeaways
• The Edmund Fitzgerald Sank Fifty Years Ago — But Its Mystery Endures
Maritime historian Fred Stonehouse recounts how the 729-foot freighter Edmund Fitzgerald sank on November 10, 1975, about 15 miles northwest of Whitefish Point. The ship went down without a distress signal, and all 29 crew members were lost—leaving one of the Great Lakes’ most haunting mysteries.
• A Storm Described as Both a Blizzard and a Hurricane
The night the Fitzgerald went down, Lake Superior raged with winds exceeding 75 miles per hour—stronger than a Category 1 hurricane. As Fred explains, the storm “exceeded 75 miles an hour in wind, and a cat one hurricane’s only 74.”
• Hubris and Hard Lessons on the Great Lakes
“This was a time when ships had the attitude that they can’t sink.”
Fred reflects on how the culture of Great Lakes shipping in the 1970s—driven by confidence and schedules—left little room for caution. The Fitzgerald’s loss changed that mindset forever, ushering in a new era of safety, respect, and humility toward Lake Superior.
• The Edmund Fitzgerald at 50: A Tragedy That Changed Everything
“The world had changed in that instance when the Fitzgerald disappeared.”
The tragedy sparked widespread reforms—from new navigation technology and onboard stress monitoring systems to emergency response protocols.
• The Ship That Became a Legend
“She has sailed from fact into legend of the Great Lakes.”
Fred explains how the Edmund Fitzgerald became immortalized through Gordon Lightfoot’s ballad, cultural memory, and even merchandise—from ornaments to craft beer. The ship’s story transcended history, turning into one of the most iconic Great Lakes legends.
• An Underwater Graveyard and a Place of Reverence
Fred describes the Fitzgerald’s final resting place, protected by the Canadian government and closed to divers since 1989. It remains a solemn memorial to the men who perished that night and a reminder of Lake Superior’s power.Connect With Us:

S6 E10: What Lies Beneath: Lake Superior’s Underwater Cleanup – With Diver Don Fassbender
Season 6, Episode 10
Show notes
Lake Superior is not only the largest of the Great Lakes, but the water quality is also some of the clearest. Yet, historically, the Lake was often a dumping ground for all kinds of debris. "Out of sight, out of mind” was an all-too-common mindset. Don Fassbender, president of Great Lakes Scuba Diving and Lake Preservation, has made it his life's mission to clean up Lake Superior’s underwater world. With volunteers, including fellow divers and kayakers, he estimates 14 tons of tires have been hauled up from Marquette MIchigan's Lower Harbor. In this episode of the Lake Superior Podcast, Walt Lindala and Frida Waara talk with Don about how his mission started and the mysteries he's found below the surface.
Key Takeaways + Notable Quotes:
A Lifelong Passion for Diving Inspired by Jacques Cousteau
“As a young man, I can recall racing home from school just so I wouldn't miss the undersea world of Jacques Cousteau.”
Vintage Diving Equipment Connects Divers More Intimately with the Water
“There's actually less things that can go wrong... Vintage kit would look like a tank, a regulator, some fins, maybe a wetsuit and a mask, and then you're off. No computers, no fancy gauges.”
Tons of Trash are Hidden Beneath Lake Superior
“We removed, what, 14 tons of tires out of Marquette Lower Harbor alone over a period of about five years. And there's still a lot of trash down there.”
Removing Underwater Debris is Complex and Laborious
Heavy items, poor visibility, and underwater hazards make cleanup efforts extremely challenging.
Why Tires are Prevalent in Lake Superior
“Tires were used as boat bumpers for years and years…as weather wears them down…they would just string another one up in its place.”
Community Involvement is Essential for Successful Cleanups
Volunteers on land, in boats, and even kayaks significantly contribute to cleanup missions.
Safety and Equipment Needs Drive Fundraising Efforts
Specialized gear and safety equipment are critical for diver safety and efficiency.
Surprising Finds Beneath the Surface Tell Unique Stories
“One of my favorite finds, a little diamond ring that was tied to a rock with a shoelace.” Every item retrieved from Lake Superior carries its own history, some humorous, some mysterious.

S6 E9: Mining the Past: How Copper Shaped the Keweenaw and Its World-Class Museum - An Interview with John Jaszczak
Season 6, Episode 9
Show notes
"If you didn’t grow it, you’ve got to mine it,” says John Jaszczak, Director and Curator of the A. E. Seaman Mineral Museum in Houghton, Michigan. Since 1838--just after Michigan became a state--geologists and miners have been collecting rock and mineral specimens as the first American Mining Rush began. Since 1855, those specimens were housed at Michigan Technological University, then known as Michigan College of Mines, making it one of the oldest museums not only in Michigan, but the Great Lakes region. In this episode of the Lake Superior Podcast, Walt Lindala and Frida Waara talk with John about the museum origins and what a visitor can find there.
Key Takeaways + Notable Quotes:
The region’s history—from Indigenous use to mining booms to today’s tourism—stems from its globally unique native copper deposit.
“The reason we’re here is because of the geology. And because of copper in particular.”
What began as a teaching collection for Michigan Tech’s School of Mines became a public museum in 1902.
“The collection started in 1885 when the university started offering courses in mineralogy.”
From discovery tales to global expeditions, the museum presents minerals as more than geology.
“Some specimens have scientific stories. Some have personal stories. Some have adventure stories.”
Under ultraviolet light, otherwise ordinary-looking minerals burst into color.
“That’s the part where most people say, ‘Wow, I didn’t expect this.’”
John’s lifelong fascination with minerals led him to volunteer, then direct, the museum alongside his career in physics.
“I started collecting minerals when I was probably five or six years old... and I just loved it.”
From working with scientists around the world to publishing in mineralogical journals, the museum plays an active role in global discovery.
“There's something magical about being the first to describe and name something.”
The Keweenaw’s native copper is on display in museum-quality form that you can’t find anywhere else.
“We have the world’s best specimens of copper. No question about it.”

S6 E8: Isle Royale: Trip Planning, Wildlife, and Wilderness Safety – An Interview with Chris Amidon
Season 6, Episode 8
Show notes
Isle Royale National Park is the Great Lakes Mecca for backpackers. This archipelago of islands is also one of our most remote National Parks so preparing for a visit takes extra planning. In this episode of the Lake Superior Podcast, Walt Lindala and Frida Waara talk with Chris Amidon, Supervisory Park Ranger for Interpretation and Visitor Services. He not only has tips for first-timers, but also has details on some new procedures, particularly when it comes to food storage.
Key Takeaways:
• Planning your experience shapes everything:
“The first thing we ask is, what type of experience are you looking to have?” From backpacking and boating to lodge stays, your approach determines your transportation and gear.• Getting to the island is part of the journey:
“Part of the Isle Royale experience is the transportation to the island. It’s that extra step that most parks don’t have.”• Food storage regulations have changed:
Starting in 2025, visitors are required to use approved food storage containers due to wildlife activity near camps and harbors.• Wildlife sightings are rare but magical:
“Encountering a moose is a really magical moment and I remember backpacking a trip I did with my daughter... those are the types of experiences that Isle Royale offer just by putting yourself in this remote island setting.”• Most of Isle Royale is federally designated wilderness:
99% of the park is wilderness, meaning motorized equipment is limited—adding to both its preservation and the physical demands of upkeep.• The Artist-in-Residence program reveals new perspectives:
“The Artist-in-Residence Program… that’s kind of my, I would say, my soft spot.” From Shakespearean sonnets to ceramic bark impressions, Chris helps curate a mix of art forms that deepen understanding of the island.• Visitation may be low, but the planning is intense:
Only about 20,000 people visit Isle Royale each year—and most come during just three months—putting pressure on resources and requiring detailed planning.Resources:

S6 E7: Coffee, Community, and the Power of the Big Lake – An Interview with Sarah Jorgenson-Hallberg
Season 6, Episode 7
Show notes
Minnesota’s North Shore has been a gathering place for centuries. Whether heading into the Boundary Waters or out on Lake Superior, Grand Marais ranks a favorite Base Camp. While it may be small in population, it’s big in spirit. Life here moves to the rhythms of the woods and waters.
In this episode of the Lake Superior Podcast, Walt Lindala and Frida Waara talk with Sarah Jorgensen-Halberg, longtime resident and owner of Java Moose, the beloved shoreline coffee shop that fuels both locals and visiting adventurers. Her daily weather video connects folks near and far to this Sweetwater Sea town and she shares what it means to live on the edge of wilderness—and how the lake’s powerful sense of place keeps people coming back to Grand Marais.
Key Takeaways:
• Grand Marais transforms seasonally: A town of about 1,300 full-time residents swells to around 50,000 in the summer, driven by tourism to the lake, North Shore, and nearby wilderness areas.
• Local entrepreneurship fuels connection: Java Moose, run by Sarah Jorgenson-Hallberg and her family, offers not just coffee but a community space for stories, weather reports, and visitor conversations.
• Lake Superior demands respect: The lake’s 34-degree waters and strong currents can be dangerous. Sarah emphasizes safety and awareness for all visitors, especially near the lighthouse.
• Winter brings peace and beauty: After the busy season, Grand Marais quiets down. Sarah loves cross-country skiing, hiking, and the sunshine of winter — despite the freezing temperatures.
• Tourism is vital to the economy: Sarah says plainly, “We would not survive without it.” Much of the local economy depends on seasonal visitors to national parks and the shoreline.
Notable Quotes:
• “I love winter. I cross-country ski a lot. I run in the winter. I get out and I hike a lot. Part of it is probably because it's quieter.”
• “It is imperative to be as safe as we possibly can be.”
• “Grand Marais and Lake Superior, it almost forces you to take that moment, right? Because it is so vast and powerful, that you just kind of stop for a moment and you're inspired.”
• “We pour ourselves out. I see that when you come into our shop, this is an extension of my home, so I'm hosting you.”
• “At the end of the day, we are welcoming you into our home.”
