Biography
He was born in McConnelsville, Ohio on September 13, 1853, and was educated in the United States and in Europe. An explorer of the American West at an early age, he was a member of an expedition that discovered the last unknown river in the United States, the Escalante River and the previously undiscovered Henry Mountains.
From 1871 to 1873, he was artist and assistant topographer with Major Powell's second expedition down the Colorado River. He joined the 1899 Harriman Alaska Expedition financed by railroad magnate E. H. Harriman. He served as librarian of the American Geographical Society (1909–1911), and became a fellow of the American Ethnological Society. He helped to found the Explorers Club in 1904.
Dellenbaugh died of pneumonia on January 29, 1935, and was buried in the Otis family plot in Ellenville, New York.
Dellenbaugh is the namesake of Dellenbaugh Butte, in Utah.
