Imagine Summit County without lofty, snow-covered mountains - imagine instead swampy lagoons and dinosaurs eating lush tropical vegetation growing on vast lowlands crossed by sluggish streams. As the reign of the dinosaurs came to a close, tremendous pressure deep within the earth began to raise the Rocky Mountains until they were high enough for glaciers to carve distinctive features on the landscape.
Sandra Mather, professor emeritus and author of the newly revised "Roadside Summit Part 1: the Geology and Vegetation of Summit County, Colorado," will tell the story of the rocks beneath our feet Tuesday at 7 p.m. in the Dillon Schoolhouse.
The oldest rocks in Summit County are about 600 million years old. Mather will bring egg cartons full of rock samples, charts and slides to show guests how the rocks have changed over time.
Mather has entertained audiences with her research since coming to Summit County in 1980 to finish her doctoral dissertation for the University of Oregon. The author has written many books about Summit County focusing on human interaction with the geologic landscape.
Her talk Tuesday evening will directly benefit the Summit County Historical Society. The cost is $25 for Summit Historical Society members and $30 for guests. All attendees will receive a signed copy of Mather's book.
