"This pass was used by David Thompson in 1807 on his way to found Kootenae House on the upper Columbia River. The pass is named, however, after the next white man to go that way: Joseph Howse, who used the same route in 1810 when sent by the H.B.C. to find what the North West Company was doing on the far side of the Rockies. Howse himself established a post near present-day Kalispell, Montana."
