Ogden, a Canadian fur trader working for the Hudson's Bay Company, was in charge of the Snake River brigade from 1824-1830. He was among the great early explorers of the American west and his travels extended from Montana to the Gulf of California. During 1824 and 1825, he led an expedition from the Flathead Post which eventually traveled portions of the Clarks Fork, Bitterroot, Beaverhead, and Jefferson Rivers as well as covering large portions of the Snake River plains.
