Thanks!
That shot was taken with the following settings:
ISO 100
35mm
f/2.8
1/200th sec
I probably should have done a smaller aperture and longer shutter speed to get a better visual of the water flow, but the temperature was in the teens, the mist from the waterfall made it that much colder, and I wanted to get in and get the hell out of there, so composing the shot didn't get a lot of thought.
