History

The mountain's name was proposed in 1919 by Arthur Oliver Wheeler to commemorate the hamlet of St. Julien, Belgium, where Canadian troops gallantly fought the Battle of St. Julien in 1915 during World War I.[5] The battle was the first mass use by Germany of poison gas on the Western Front. It also marked the first time a former colonial force (the 1st Canadian Division) defeated a European power (the German Empire) in Europe. The name was officially adopted in 1920 when approved by the Geographical Names Board of Canada.[4] The first ascent of the mountain was made in 1930 by D. Duncan and A. F. Megrew.[6]

Geology

St. Julien Mountain is composed of sedimentary rock laid down during the Precambrian to Jurassic periods. Formed in shallow seas, this sedimentary rock was pushed east and over the top of younger rock during the Laramide orogeny.[7] Precipitation runoff drains into Mons Creek from the south slope, eventually reaching the Columbia River, and Forbes Creek from the north, a tributary of Howse River.

Climate

Based on the Köppen climate classification, St. Julien Mountain is located in a subarctic climate zone with cold, snowy winters, and mild summers.[8] Temperatures can drop below −20 °C with wind chill factors below −30 °C. This climate supports the Mons Icefield to the immediate north.
