Monument Falls is a glacier-fed waterfall in Glacier National Park, Montana, carrying meltwater from Sperry Glacier downhill toward Avalanche Lake. It stands out within an area of many nearby unnamed cascades, giving it a distinct identity among the park’s clustered water features. Its significance lies in this close connection to the high alpine landscape and to the runoff produced by one of the region’s glaciers, linking the falls directly to the mountain environment that shapes it.
