Sperry Glacier Falls

Sperry Glacier Falls is one of the tallest waterfalls in Glacier National Park, spilling about 2,300 feet down the headwall above Avalanche Lake from the basin harboring the Sperry Glacier. The falls consist of three distinct sections separated by stretches of talus-based cascades. The largest part of the falls drops about 900 feet on its own, with the upper and lower sections each standing about 300-350 feet each, and the remaining height of the falls made up of the cascades between each section. The base of Sperry Glacier Falls drops down the same cliff band which produces Monument Falls, and it could be fairly argued that both streams dropping side-by-side should actually be collectively referred to as Monument Falls, with Sperry Glacier Falls terminating at the base of the 900-foot section of the falls. This is something we will need to re-evaluate upon actually visiting the area and surveying the falls in question. We had previously referred to this waterfall as Avalanche Basin Falls, however after re-examining the makeup of the waterfalls in the Avalanche Lake cirque, we deemed it appropriate to adjust the names of several features to more properly reflect their geographic relationships in the basin. Given that this waterfall is fed by the primary melt stream originating from the Sperry Glacier, it became fitting to re-title this waterfall after the glacier, while the falls immediately to the north (which we formerly referred to, incorrectly, as Monument Falls) has now assumed the title of Avalanche Basin Falls.
