Avalanche Lake is located in Glacier National Park, in the U. S. state of Montana. Avalanche Lake is southwest of Bearhat Mountain and receives meltwater from Sperry Glacier.[2] Avalanche Lake is a hike from the trailhead along the Trail of the Cedars.[3] The trail roughly follows Avalanche Creek, a whitewater creek that drains out of Avalanche Lake and drains into Haystack Creek.[4] When measured in August 1910, the maximum depth of the lake was near the upper end.[5]
Avalanche Lake was named in 1895 by a party including Dr. Lyman Sperry, namesake of the Sperry Glacier, who witnessed many avalanches during their stay.[6]
Though most lakes of similar size and elevation in Glacier National Park do not have fish, Avalanche Lake is a popular fishing location among anglers.[7] Yellowstone cutthroat trout are native to the lake.[8]
