“An Introduction to SCREE–The Sesquicentennial Colorado River Exploring Expedition”

Thomas Minckley, Associate Professor of Geography, University of Wyoming.

When Powell journeyed down the Green and Colorado rivers, he found an arid land–a contrast that defines America’s southwest and all life within it. The SCREE Expedition on the 150th anniversary of Powell’s voyage is not just an exciting rafting trip; it explores how Powell’s legacy shapes the modern West even today. 

6:30-8:30 PM

“John Wesley Powell & the Colorado River Basin’s Past, Present and Future”

Panel of experts from universities in Wyoming, Utah and Colorado.

Powell’s river expeditions shaped his visions of water, public lands and Native Americans in the Arid Region. This panel explores the nature, impact, and future relevance of Powell’s vision in the Colorado River Basin.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]
