Natural Bridge Falls on the Boulder River south of McLeod, Mont., is one of Montana's most spectacular and fleeting waterfalls. The falls only flow at the height of summer runoff, often for not more than a day or two each year. This season's flows peaked on June 6, 2012, when Natural Bridge Falls put on a stunning display.
