Formed in shallow seas, this sedimentary rock was pushed east and over the top of younger rock during the Laramide orogeny. Climate Based on the Köppen climate classification, Mount Louis is located in a subarctic climate zone with cold, snowy winters, and mild summers. Temperatures can drop below -20 °C with wind chill factors below -30 °C. Weather conditions during summer months are optimum for climbing.
