Rearguard Mountain is a 2,744-metre (9,003-foot) summit located within Mount Robson Provincial Park in British Columbia, Canada. It is part of the Rainbow Range which is a sub-range of the Canadian Rockies.

History
[edit]It was named in 1922 by the Interprovincial Boundary Survey to describe the point of view of those approaching Mount Robson since the mountain is located at the rear of Robson.[4]
The mountain's name was officially adopted February 1, 1923, by the Geographical Names Board of Canada.[2] It was labelled on Arthur O. Wheeler's 1911 topographic map of Mount Robson.[5]
The first ascent was made in 1913 by an Alpine Club of Canada party.[1]
Climate
[edit]Based on the Köppen climate classification, Rearguard Mountain is located in a subarctic climate zone with cold, snowy winters, and mild summers.[6] Winter temperatures can drop below −20 °C with wind chill factors below −30 °C. The months June through September offer the most favorable weather to visit. Precipitation runoff from the mountain drains into the Robson River.
Geology
[edit]The mountain is composed of sedimentary rock laid down during the Precambrian to Jurassic periods and pushed east and over the top of younger rock during the Laramide orogeny.[7]
