The first ascent was made in 1938 by E. Cromwell, E. Cromwell jr., F.S. North, J. Monroe Thorington, guided by Edward Feuz jr.[1]
In 2005, Bill Corbett, author of "The 11,000ers of the Canadian Rockies," climbed to the top of Mount Cromwell. At the summit, his GPS registered 11,006 feet. So perhaps Mount Cromwell should be included in the list of the Canadian Rocky Mountains that are over 11,000 feet in elevation.[1]
Climate
Based on the Köppen climate classification, Cromwell is located in a subarctic climate zone with cold, snowy winters, and mild summers.[3] Winter temperatures can drop below -20 °C with wind chill factors below -30 °C. Precipitation runoff from the mountain drains into the Athabasca River.
