lived in a village a short distance above what is now Kooskia with his band of Nez Perce. This regular home was well within the boundaries of the reservation created in 1863, but just before the Nez Perce War an American General was sent to arrest Chief Looking Glass and all other Nez Perce with him. When trigger-happy militiamen opened fire into the village, many Nez Perce died and their village was destroyed in the scuffle. Because of this incident, Looking Glass joined with the Nez Perce for the Nez Perce War. The name of the town is likely a contraction of the Nez Perce word "koos-koos-kia," a diminutive which refers to the Clearwater River, the lesser of the two large rivers in the vicinity, the other being the Snake. The town was first named Stuart, after James Stuart, a Nez Perce surveyor and merchant. The railroad arrived in 1899 and named its station "Kooskia," because there already was a railroad station named "Stuart" in the state. The town went by both names for the next decade until it was formally renamed in 1909. Kooskia is within the Nez Perce Indian Reservation. Similar to the opening of lands in Oklahoma, the U.S. government opened the reservation for white settlement in November 1895. The proclamation had been signed less than two weeks earlier by President Cleveland.
Tramway
Starting in 1903, Kooskia was the terminus of an aerial tramway up to the elevated Camas Prairie. It carried up to of grain per day in its thirty buckets and warehouse facilities were present at both ends of the cable line, with a combined capacity of 100,000 bushels. Following the completion of the Camas Prairie Railroad's second subdivision to Grangeville in 1909, the tramway gradually lost patronage and was discontinued in 1939. It climbed west-southwest toward Lowe ; some older maps listed Kooskia as "Tramway." It experienced a significant accident in 1907 due to cable failure, fortunately without fatalities.
During the final two years of World War II, the Kooskia Internment Camp was located about northeast of the town. Originally a remote highway work camp of the Civilian Conservation Corps in the 1930s, it was later run by the Federal Bureau of Prisons and then converted in 1943 to house interned Japanese men, most of whom were longtime U.S. residents, but not citizens, branded "enemy aliens." It was so remote in the western Bitterroot Mountains that fences and guard towers were unnecessary. The site, now an archaeological project, is northeast of Lowell on U.S. 12, on the north bank of the Lochsa River.
