The Precambrian Geology of the Baraboo Hills

In this March 2019 talk for Wednesday Nite @ The Lab (WN@TL), WGNHS geologist Esther Stewart shares her insights into some of Wisconsin’s oldest rocks. It’s a story of reading the deep-time sedimentary record and how old mine records and outcrops reveal a history of ancient rivers, oceans, and faulting in Wisconsin.

WN@TL is a science outreach program from UW–Madison in which researchers in myriad fields give free public presentations describing their work. PBS Wisconsin broadcasts WN@TL talks as part of their University Place series.
