Merlin Lake

A turquoise glacial tarn at 2,268 m (7,440 ft) in the Skoki Valley of Banff National Park. Fed by glacial meltwater from Mount Richardson and Merlin Peak; rock flour (glacial silt) scatters sunlight, giving the lake its characteristic colour. The lake drains into Merlin Creek, which joins the Pipestone River (Bow system).

Access

~3 km trail from Skoki Lodge gaining ~200 m; the trail was built primarily by Lawrence Grassi (Lake O’Hara trail-builder). Trail crosses Merlin Meadows (2,090 m) and ascends a headwall; one or two gullies may require hands for balance. Subalpine-to-alpine progression: Engelmann spruce and subalpine fir give way to subalpine larch, which turns gold in late September (“larch season”). Above treeline: alpine tundra, talus, wildflowers (Indian paintbrush, forget-me-nots).

Geography

The lake sits in a basin behind the Wall of Jericho; a castellated limestone fin that separates the Merlin basin from the Skoki Lakes basin (Myosotis, Zigadenus). “Dragon’s Drink” meadow lies northwest of the lake, beneath the pinnacles of Merlin Castle. It is one of the strongest larch-season objectives in the Skoki area.

Management
