Canada - British Columbia - Marble Canyon Kootenay National Park

Marble Canyon Kootenay National Park

Sent by Gail, a postcrosser from Canada.

This is from Wikipedia : Marble Canyon is a small canyon in the south-central Interior of British Columbia, Canada a few kilometres east of the Fraser River and the community of Pavilion, British Columbia, approximately midway between the towns of Lillooet and Cache Creek. A collapsed karst formation, the canyon's name comes from the brilliant limestone of its walls. Despite the name, however, the bedrock is microcrystalline limestone (sedimentary rock) rather than marble (metamorphic rock). The north wall is over 965m (3150') high above Pavilion Lake and is the southernmost extent of the Marble Range; the south wall is c. 515m (1500') and is the northern extremity of the Clear Range. Higher peaks lie in behind the walls, increasing the depth if measured from their summits.
