Simpson River (British Columbia)

Simpson River, in Kootenay National Park, is a tributary of Vermilion River flowing through Simpson Valley; which in turn is a tributary of the Kootenay River and eventually the Columbia River. Its named tributaries include the North Simpson River, Surprise Creek, Lachine Creek, and Verdant Creek. The river's headwaters form on the north slope of Nestor Peak.

Simpson River is named for Sir George Simpson Governor of the Hudson's Bay Company which owned Ruperts Land. He discovered it while leading an expedition through this area of the Rocky Mountains in 1841, seeking a shorter route to, what the British called the Columbia District and Anerican's referred to as Oregon Country.
