History

The first ascent of the peak was made in 1910 by Katherine Longstaff and her brother Dr. Tom Longstaff, with Rudolph Aemmer as their guide.[4]

The mountain was named Sunburst Peak in 1953 after Sunburst Lake, which had been named by the Interprovincial Boundary Survey.[4] The name was officially changed by the Geographical Names Board of Canada to Sunburst Peaks (plural) on February 15, 1983 with the intention extended to apply to three peaks.[5] [2]

Geology

Sunburst Peak is composed of sedimentary rock laid down during the Cambrian period. Formed in shallow seas, this sedimentary rock was pushed east and over the top of younger rock during the Laramide orogeny.[6]

Climate

Based on the Köppen climate classification, Sunburst Peak is located in a subarctic climate zone with cold, snowy winters, and mild summers.[7] Temperatures can drop below −20° C with wind chill factors below −30° C. Precipitation runoff from the peak drains into headwaters of the Mitchell River.
