Marble Canyon surrounds Tokumm Creek just above its confluence with the Vermilion River, at the north end of Kootenay National Park in the Canadian Rockies of British Columbia.[1] South of the canyon on Highway 93 is Numa Falls on the Vermilion River.
As described by Canadian Alpine Journal in 1913, "[Tokumm Creek] joins Vermilion River through a magnificent gorge, or box canyon, so narrow that at several places the fissure, for it seems little more than a crack in the rock strata, is bridged by great boulders that have become wedged across it. It was a feature well worth seeing."[2]
