So-named during the 1920's by Geoff Capes and a hiking party on their way to Comox Glacier. It was raining and appeared hopeless for mountaineering. As they started out, a black cat ran across in front of their car. Thereafter the weather cleared and the climb was deemed a success, attributed to the luck of crossing paths with a black cat.
