The Wenkchemna Peaks of Banff National Park provide a glorious backdrop to the aquamarine waters of Moraine Lake in the Valley of the Ten Peaks. Wenkchemna is the Stony Indian word for the number ten. This high glacial valley south of Lake Louise provides a small sanctuary for a small population of grizzly bears. The waters of this lake take on a cerulean hue in summer as the meltwater from small remnant glaciers flows into the lake with its burden of ground-up glacial silt. Suspended in the water of the lake, this milky solution absorbs the light at the short end of the visible-light spectrum causing the water to appear blue green.
