To be more specific, this is the lower part of the palouse falls.
The height of the lower part is 180 feet which makes it higher than the Niagara falls. And, the height of the cliff I was standing on is about 377' above the pool of water. My tripod was within 1 foot of the edge of the cliff... it was scary to look down. I took this shot without looking at the viewfinder. This was taken at 14mm focal length using live view. Later i cropped it after correcting distortion.
