Geology in Montana along the Missouri River: Canoeing with Lewis & Clark.

17-21 August 2015
Great Falls, Montana, United States
Participants will explore a number of classic geological sites that affected the Lewis and Clark expedition in Montana on this six day excursion, including the Gates of the Mountains canyon within the Montana Thrust Belt, Lewis’ “Tower Rock” atop late Cretaceous volcanics, hikes to the Great Falls of the Missouri through Lower Cretaceous deltaic sediments, and the Marias/Missouri River “decision point.”

Although geology as a science was in its infancy when President Thomas Jefferson commissioned this expedition in the early 1800s, the progress of the “voyage of discovery” was heavily influenced by the geology encountered along the way. Lewis, schooled as a Naturalist, described the geological landscapes he saw in vivid detail throughout his daily journals.

This excursion will also include visits to the Lewis & Clark Interpretive Center, First People’s Buffalo Jump, and the famous C. M. Russell western art museum.
