The trail to Black Prince Cirque, which is found in Peter Lougheed Provincial Park along Secondary Road 742 between Kananaskis Village and Canmore, makes a pleasant, if not exactly awe-inspiring, half-day hike. My brother and I did it on the afternoon of September 8, 2001, after we had hiked Ptarmigan Cirque that morning.
The trail starts up a steep abandoned logging road and heads into thick forest before arriving at Warspite Lake. Or, as we discovered, where Warspite Lake ought to have been. Southern Alberta had been suffering from a weeks-long drought that summer, and the area had only been reopened to hikers that weekend. What the guidebook called a tarn had essentially vanished, and not recently, either. For us, this underlined how dry it had been more than anything else.
Worthy of note: the mountains in this area were named after World War I British dreadnoughts, thus they ought to be Mount Warspite and Mount Black Prince, italics included, but then Im just being pedantic (as usual).
