Sounds like the same canyon that the Water Caves are in. The Water Caves is an area in a canyon also to the left off of 3N14 where there is a long section where the canyon is clogged with lots of big granite boulders all piled on top of eachother and there are space you can find inside like caves and when the water is flowing there are waterfalls and also some interesting pools in different place in the rocks. I've explored that area from top to bottom and you really have to work to get into all the cool places, its worth it though. Spring after rains is best since this canyon is dry most of the year. Sounds like the waterfall is further down the canyon from the Water Caves, is that right Laughing Bear?
