John Wesley Powell (Explorer)

John Wesley Powell was a 19th-century American explorer best known for his daring expeditions in the American West, particularly his historic journey down the Colorado River through the Grand Canyon in 1869. A geologist and former Civil War soldier, Powell led the first successful rafting expedition through this rugged terrain, conducting important scientific observations along the way. He advocated for conservation and responsible management of the West’s natural resources. Powell also played a significant role in the establishment of the U.S. Geological Survey and promoted the idea of federal land stewardship, which influenced modern environmental policies.
