Welcome back Earth Campers! This year we are expanding Earth Camp to a second summer and bringing back our students from last summer for another outdoor Earth adventure. Our first stop was Mackinac Island. We started off the day learning about sedimentary rocks, the Michigan Basin, and how the Mackinac Breccia was formed.
After that, we headed out on bikes to explore the island and find the Mackinac Breccia, as well as shoreline features from glacial Lakes Nipissing and Algonquin such as sea stacks, arches, caves, and the former headlands.
It was a great (and exhausting) day! About 10 miles of biking – the last stop was the highest point on the island – Point Lookout and Fort Holmes.
Off to Tahquamenon Falls and Pictured Rocks tomorrow.
