Follow Along on a Bicycle Tour That Teaches About Hudson Valley’s Glacial History

A student-led Cycle for Science trip will follow the footsteps of an ice sheet that buried the NYC area under a mile of ice during the last ice age.

This is the first of three blog posts documenting a bicycle trip through the Hudson Valley, led by Columbia University PhD student Elizabeth Hillary Case. Read the second post here, and the third here.

Hello! I’m Elizabeth, a PhD student at Columbia University and the Lamont-Doherty Earth Observatory, and I study how glaciers form and flow. For the next week (October 7-11), I will be riding my bicycle from New York City north through the Hudson Valley to Poughkeepsie, NY. I’ll be following the 18,000-year-old footsteps of the retreating Laurentide Ice Sheet, which buried this area under a mile of ice during the last ice age.

Along the way, I’ll be stopping at schools to teach hands-on lessons about the Laurentide Ice Sheet, how it helped shape the Hudson River, and how we use our past to understand our future. I’m excited to share with you adventures along the way — you can follow along here on State of the Planet.

This trip is a program of Cycle for Science, an organization I co-founded in 2015 with Rachel Woods-Robinson from UC-Berkeley, when we rode across the United States teaching lessons about renewable energy using miniature, solar-powered, 3D-printed bicycles. We cycled alongside wild horses, came face-to-face with a grizzly in the Tetons, and reached over 1,000 students in 8 states.

The goal of Cycle for Science is to create interactive lessons related to the work of early-career scientists. It’s an effort to introduce students to the creativity, diversity and urgency of climate- and renewable energy-related research, while both literally and figuratively meeting communities where they are.

If you’d like a taste of a previous trip, check out our September program. As the climate marches swept the world, Rachel reached the ocean on a different Cycle for Science trip pedaling through the Netherlands.
