Powell Expedition—Flora and Fauna. Then and Now.
This year marks 150 years since John Wesley Powell and his nine-man crew conducted a scientific expedition of the Green and Colorado rivers. In addition to the goal of mapping the river basin, Powell’s group collected fossils and observed flora and fauna as they journeyed down the river. What did they observe, and what is the focus of USGS ecological studies in the Colorado River Basin now?
