Join Cheyenne geologist Ed Heffern as he discusses why and how Cheyenne came to be where it is from a geologic perspective. There will be a presentation and discussion (including hands on show and tell) of rocks and landscapes that can be found in the Cheyenne area including: the Gangplank, Curt Gowdy State Park, Granite Canyon, and the Big Hole. You will get to see geologic maps and diagrams, photos, lots of rocks, and learn what’s underneath Cheyenne – besides rabbit holes!
Ed worked as a geologist for 32 years with the US Bureau of Land Management in Cheyenne as well as Miles City, Montana, and Santa Fe, New Mexico, before retiring in 2011. Since then, he taught several geology classes at Laramie County Community College, worked on a mapping contract with the Wyoming State Geological Survey in Laramie, and volunteered two seasons at Petrified Forest National Park in Arizona. Ed has a special interest in coal fires and clinker rock in the Powder River Basin of northeast Wyoming and southeast Montana, and has published several articles and maps on the subject.
