The way I got the job mapping the filming locations at the park, the first time I went to it, I asked to see the Planet of the Apes locations, and they did not know for sure, just a general area—unbelievable! So I approached the head Ranger/Docent, and I told him I could geo-track the exact spots by triangulating the mountain locations in the shots, since they do not change, and it would be something people would like to know while visiting the park. We ended up mapping over 100 movie locations—now there are signs donated by the Hearst Corporation.

The waterfall was created by Using a firehose (and was also used Doctor Dolittle (1968). The water level in the pond was too high, so I could not get an exact angle, but the tree in the shot is growing out of the stump of the tree that is in the 1968 shot. The "cliff" is literally a drainage ditch at the edge of the cornfield. It is very over grown—that is the best shot you can get (the grass blocks the view if you go to the proper location).
