  • 344 - Paddling Among Icebergs
    Oct 17 2024

    Ever since I discovered how to read the glaciated landscape of Northern Minnesota and Wisconsin, I’ve been fascinated by these massive forces of nature. Admiring them from afar, seeing them up close, paddling among icebergs, touching their ice…glaciers are even more amazing than I’d expected. This week I’ve been busy leading field trips, but I’ve been dreaming of a time when I was a participant on two field trips that involved paddling near glaciers in Alaska.

  • 343 - A Gift of Geology, Artesian Wells
    Oct 10 2024

    By Elliot Witscher with Emily Stone
    In the bright sunlight and heat of the afternoon, the cool, fresh, flowing water from a pipe in Prentice Park in Ashland, WI, was a welcome treat. I wasn’t expecting to find a unique geological feature in an unassuming city park. But walking down the hill from the parking lot, we found a plain metal pipe, surrounded by gravel, with water gushing from it. Standing in a circle with the 20 other people also taking the Wisconsin Master Naturalist Volunteer Training, I learned from Professor Tom Fitz that this was a flowing artesian well.

  • 342 - Four Out of Five Loons Agree
    Oct 3 2024

    As our water taxi motored into the harbor, a gray-headed water bird floated around the corner of a barnacle-crusted rock. A Pacific Loon!
    Having spotted one new species of loon, my interest in seeing the others grew. The afternoon that I arrived at the Toolik Field Station to prepare for doing caribou research, I took a short walk around the base to get a feel for the area. The tremolo of a loon flying overhead sent a thrill down my spine, and I watched the large bird land on the far side of Toolik Lake. Were they a Common Loon? They sounded similar. But the logo for Toolik features a Yellow-billed Loon, and I was sure the scientists would have chosen them deliberately. Now that I’d seen the most similar loon to the ones I’d left back home, my last goal was to see the most different loon.

  • 341 - First Grade Spiders
    Sep 26 2024

    A small group of first graders nearly vibrated with excitement as they gathered in a circle on the carpet at the front of their room. They remembered me from last school year, when I’d brought tubs full of nature stuff to their kindergarten classroom. For those first Museum Mobile visits, we focused on exploring nature using our five senses. Now, as first graders, I explained, we get to practice those skills again…by using our eyes to make observations about spiders! I was heartened by the wave of enthusiasm – not fear – that rippled through the group.

  • 340 - Grand Canyon Connections
    Sep 19 2024

    Floating down the river, exploring the side canyons, relaxing around camp, I was always on the lookout for both the novel and the familiar. A giant insect I’d never seen before but knew immediately to be a Tarantula-hawk Wasp caught my attention just as easily as the glossy black feathers of a Common Raven. After a few days of pointing out something I’d noticed, or explaining the basics of a geological feature, I found more questions coming my way from the other participants. With each teachable moment, I felt more connected to both the canyon and my fellow rafters. I wasn’t surprised at the way this unfolded, and probably, neither are you.

  • 339 - Listening in Elk Habitat
    Sep 12 2024

    Due to a stuffy nose, I’m not recording a new episode for you this week. I did pull forward this episode from 2023 about the elk herd near Clam Lake.

    Morning mist hung low in the sky as a dozen elk ran across a clearing. A similarly sized herd of Museum members held our breath and grinned at our good luck. It was luck 3 billion years in the making.

  • 338 - On Top of the World
    Sep 5 2024

    Curtains of vibrant lights were moving just above the horizon. The aurora! My jaw must have dropped as I stumbled backward to lean against the car, and tears welled up as I tilted my head back for a better view. The moon hung full and bright on my east. To my west, spruce trees were silhouetted against the faint, rosy afterglow of the setting sun. And all across my southern sky, northern lights danced in curtains of green and white and pink. The curtains were woven of many wispy streaks, as if I was seeing the individual particles of solar wind blazing through our atmosphere. Northern lights are not just an awesome benefit to living on Earth; they are an absolute necessity to our survival. Our Earth defends us. And the result is unspeakable beauty.

  • 337 - Isle Royale How Did You Get Here
    Aug 29 2024

    With the rough, rolling, cold, wet ferry ride behind us, we disembarked gratefully at the Windigo dock on the southwest corner of Isle Royale National Park. Isle Royale, a 45 mile long and 9 mile wide bedrock island, is teeming with life that somehow made the treacherous journey. We hoisted our packs and started off down the trail. Before long, we met several pairs of hikers just ending their trips. We asked about their route on the island, their hometown, and which ferry they took. In essence, we asked “How did you get here?” Mostly they used the water route, but one couple arrived by air in a float plane. Historically, making winter crossings by dogsled was also common. Isle Royale is not an easy place to get to, or to get around, and yet life surrounded us on all sides. Soon I started asking “How did you get here?” to everything we saw.
