The Selkirk Mountains are a mountain range spanning the northern portion of the Idaho Panhandle, eastern Washington, and southeastern British Columbia which are part of a larger grouping of mountains, the Columbia Mountains. They begin at Mica Peak and Krell Hill near Spokane and extend approximately 320 km north from the border to Kinbasket Lake, at the now-deserted location of the onetime fur company post, Boat Encampment.
