150th Anniversary of Powell's exploration of the Colorado River exhibit gra

150th Anniversary of John Wesley Powell’s Exploration of the Colorado River

In May 1869, John Wesley Powell led a team of 9 explorers on an exploration of the Green and Colorado Rivers, one of many surveys of portions of the American West. Three months later, on August 30th, Powell and his remaining companions completed their expedition through the Grand Canyon. Powell would return for future surveys over the next decade, and with others, would formalize the federal government’s role in understanding and stewarding Western lands. Visit the Government Information Collection on the Library’s Lower Level to explore Powell’s findings and the genesis of the United States Geological Survey (USGS).

We’ll be celebrating the 1869 Colorado River expedition all summer long on campus and at distance sites throughout Utah! For more information, including links to digital materials, click here.
