Join geologist Steve Stresky for a hike that will detail the fascinating geology along the upper portion of Red Grade Trails in Sheridan Community Land Trust’s upcoming Discovery Session – The Rocky History of Red Grade Trails.

Steve will tell a story millions of years in the making as attendees view prominent features like the Bighorn Anticline and Moncreif Ridge on a hike from Drifter Trail to the First Grade Overlook. Steve will draw upon more than 40 years as a professional geologist and a lifelong passion for adventuring in the Bighorns to teach hikers about the structural evolution of the mountains, the geometry of strata along its flanks, the differences between rock types, their potential for aquifers and how those rock types and aquifers affect the landscape and how it’s used. He’ll also discuss the origin of Red Grade Spring and how such a spring with no seeming source above can form.

This Discovery Session will take place on Thursday, August 20 at 5:30 p.m. Please meet at Springs Trailhead Parking Lot (upper lot) at Red Grade Trails, located at the base of the Bighorns along Highway 335. Attendees are asked to wear hiking footwear and bring water.
