Mount Forbes is one of the most outstanding in the Rockies and is, in some ways, quite similar to Mount Assiniboine. At 3612 meters Mount Forbes is only six meters lower in elevation and, like Assiniboine, it towers some 350 meters higher than the neighboring peaks, its pyramidal summit often hidden in the clouds while lesser, but still very respectable, nearby mountains are visible. Mount Forbes is the highest mountain entirely within Banff National Park.
James Outram and Norman Collie's parties combined forces in 1902 to attempt Mount Forbes. Collie greatly admired the peak referring to, "awesome precipices soaring to a ramp of stainless snow whose knife-edged ridges culminate in a sharp pyramid that pierces the blue heavens like a javelin."
