Ice Age Geology (Bird & Nature Adventure)

Join Luke Zoet, UW-Madison professor of geology, for a walk and talk about the glaciated landscape at Cherokee Marsh. We will take the trail to Hickory Island and imagine standing on the edge of an ancient deep Yahara River canyon, now almost filled with sediment. We'll stop to look at an "erratic" boulder dropped by the Ice Age glacier and at a Native American mound. Next, we'll climb North Hill to see the general northeast-southwest orientation typical of Ice Age moraines and the relatively flat hilltop that indicates a bedrock remnant was scraped flat by the huge glacier. Heading back down and around the hill, we will view ancient bedrock in the fenced area on the vertical hillside, where farmers quarried rock. Finally, we will observe the open, flat marsh now growing on ancient Lake Yahara sediment.
