The mountain was named in association with Sampson Creek, which flows south from the mountain. In 1911, E.N. Sampson acquired a preemption located on the east side of the locally named Sampson Creek.[4] It was spelled Samson Mountain when it was first adopted in 1967 on maps. The spelling was officially corrected and adopted April 29, 1983, by the Geographical Names Board of Canada to conform with the creek.[2] The first ascent of the mountain was made in 1935 by Preston Tait, John Ronayne, and Ronald Ronayne.[1]

Climate

Based on the Köppen climate classification, Mount Sampson is located in a subarctic climate zone of western North America.[5] Most weather fronts originate in the Pacific Ocean, and travel east toward the Coast Mountains where they are forced upward by the range (Orographic lift), causing them to drop their moisture in the form of rain or snowfall. As a result, the Coast Mountains experience high precipitation, especially during the winter months in the form of snowfall. Temperatures can drop below −20 °C with wind chill factors below −30 °C. The mountain and its climate supports an unnamed glacier on its northern slope. The months July through September offer the most favorable weather for climbing Sampson.
