Fall Creek Falls descends 60 ft into the Snake River near Swan Valley. I was disappointed that there was a light rain with cloudy skies when I visited but, since it is advertised as a place to climb on the falls and sit in the pools (see photo #4), I was glad that the weather wasn't warm and sunny with people on the falls.
The first 3 photos are mine taken at 1/6 sec. with a 3-stop ND filter. The last 2 photos are from web sites advertising the falls. The photographer is not credited.
