Ketchum | USA Idaho

Ketchum is a world-renowned resort town in Blaine County, Idaho. Situated in the Wood River Valley at the foot of Bald Mountain, it serves as the primary service and cultural center for the Sun Valley resort area.

Historical Timeline

The town was founded in 1880 during a silver and lead mining boom and named after David Ketchum, a local trapper. Following the 1890 silver crash, Ketchum survived as a regional livestock and sheep-shipping hub. The city’s modern identity began in 1936 with the opening of the Sun Valley Resort, which transformed the valley into the first destination winter resort in the U.S. Ketchum remains historically significant as the final residence and burial place of author Ernest Hemingway.
