Two Dog Flats

From Two Dog Flats, glacially-carved peaks rise sharply from the grasslands below, marking the boundary between Glacier's frozen summits and the unglaciated Great Plains. Ancient ice sculpted U-shaped valleys and left behind cirques and hanging valleys; the prairie floor beyond the park boundary remains untouched by glaciation. This ecotone merges three ecosystems: alpine tundra on peaks, subalpine forest on slopes, and grassland on the flats. Wildlife congregates here—elk herds, bighorn sheep, and bears traverse this prairie-to-peaks transition, especially during early-morning hours.
