Nan Evans' conversation with geologists Michael Machette and Jeff Tepper explores significant rocky outcropings and geology in eastern Jefferson County. This episode will consider the impacts of glaciation and Peregrine Rock, a glacial erratic, a short hike from Tamanowas Rock. And, yes, east Jefferson County was covered by glaciers thousands of feet deep. (Airdate: November 2, 2022)
