John Wesley Powell

John Wesley Powell was a Civil War veteran who had lost part of one arm as a result of combat.  He was a professor of natural history at Illinois Wesleyan Collage, who took field trips with his students to the Rockies.

He came to the Grand County region looking for a vantage point to conduct an exploration of the Colorado (the Grand) River. With six local men he made the first recorded ascent of Long's Peak, the 14,255 foot landmark of the Front Range, on August 23, 1868.  From that summit he could view much of the headwaters area of the river.

Descending back into Middle Park, he ventured to Gore Canyon where he decided the turbulent rapids were too dangerous for his boats.  He decided to take an exploratory  party of students to the Green River in Wyoming, a tributary of the Colorado.  Losing one boat in that expedition, the party made the first known trip through the Grand Canyon in 1869.

He later became leader of the first U.S. Geological Survey, and because of his study of Indian tribes, the first head of the U.S. Bureau of Ethnology.
