The photo above, showing a lovely scene in Glacier National Park Montana, was captured along a fast-moving section of McDonald Creek. This is the longest stream within the park (approximately 25 mi or 40 km in length). Its headwaters are on Mount Geduhn in the Livingston Range. Before emptying into Lake McDonald, the stream had to cut its way through layers of shale, limestone and sandstone of the Belt Supergroup. McDonald Creek is one of the many glacial streams in Glacier National Park falling hard from the high country to the plains below. It's tranquil this time of year (early fall), but during spring snowmelt, the rush of water pouring downstream can be deafening. Note that the chartreuse patch of light at lower center is actually the reflection of coniferous trees standing well above the water line off to the left. Photo taken in September 2012.
Photo details: Nikon D800e camera; 200-400mm lens -- shot at 200mm; ISO 200; F/32; 0.40000 sec. exposure.
