# Chemult, Oregon

Chemult /ʃɛˈmoʊlt/ is an unincorporated community and census-designated place in Klamath County, Oregon, United States, on U.S. Route 97 near the drainage divide between the Klamath and Columbia Rivers. Chemult has a population of about 80 people. Chemult's elevation is 4,764 feet (1,452 m).
The locale was originally established in 1924 as a station on the Southern Pacific Cascade Line named "Knott" during construction. The station's name was changed to Chemult when the line opened in 1926 and a post office was established the same year. The name Chemult comes from a Klamath chief who was one of the 26 who signed the Klamath Lake Treaty of October 14, 1864.
Amtrak's Coast Starlight stops in Chemult daily at the Chemult Amtrak station, and Pacific Crest Bus Lines stops daily at the station on its route from Klamath Falls to Bend. There is also a Winema National Forest ranger station within the community.
