Find the upper falls by parking per the directions to Ames Wall by the power station. Take the trail up along the roadcut for about 15min. You will pass by the lower falls--keep on going a few more minutes to the next small canyon for the larger falls.
The climbing is fun. Very fat at the time although the climber's right side was a little thin at right-center. Water could be seen rushing down behind the ice. But the far right side presented some interesting climbing--steep and slightly chandeliered.
Top rope setup is easy from trees. Leading is possible, but as you can see from the picture, there is a gap at the bottom of the left side.
Protection
The fall is about 90ft. so bring enough screws for that.
