Gardiner to the Beartooths Geology Field Trip
Day Trip, Geology, Natural History
This ambitious field trip from Gardiner, Montana, to the 10,947-foot Beartooth Pass will take you on a journey through time and space to piece together the vast and complex geologic history of Yellowstone Country and its diverse ecosystems.
During a busy day of roadside stops and very short hikes, you’ll visit outcrops, roadcuts and landforms that illustrate some of the big stories that shaped the landscape you see to-day. Waterfalls, mountain lakes, lava flows, cataclysmic volcanic super eruptions, glacial ice dams, petrified forests, the largest terrestrial landslide on the planet, and some of the oldest rocks in the world: this exceptionally gorgeous route tells a big chapter of the epic geologic story of the Greater Yellowstone Ecosystem as written in the rocks.
About the instructor
John Gillespie has been fascinated by the geology of Yellowstone since his first visit in 1972.

He now applies his 40-year career in natural resources to Yellowstone. He is a certified interpretive guide, believes in life-long learning and regularly explores Yellowstone Country geology from his home just north of the park in Paradise Valley.
