Summary Authors: George Seielstad; Jim Foster
The photos above show two views of Running Eagle Falls in Glacier National Park, Montana. The one at the top was taken on the first day of summer. At this time of year, snowmelt from higher elevations together with reliable springtime rainfall fills the stream (Two Medicine Creek) needed to sustain both falls. By late summer, however, the upper falls is a dry rock shelf. Since snowmelt ended weeks ago and the drier summer season yields little rainfall, there's no longer enough water in the stream to supply flow for the upper falls.
