Rearguard Mountain with Mount Robson

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. Its nearest higher peak is Mount Robson, 4.0 km (2.5 mi) to the southwest.[1] Rearguard is situated between Berg Lake and the Robson Glacier.

History[]

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 made official on 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[]

Based on the Köppen climate classification, Rearguard Mountain is located in a subarctic climate zone with cold, snowy winters, and mild summers.[6] Temperatures can drop below −20 °C with wind chill factors below −30 °C. In terms of favorable weather, June through September are the best months to climb. Precipitation runoff from the mountain drains into the Robson River.

Geology[]

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]
