John, heres a shot of the landing, in the far left of the picture taken July 11 2006, not sure how high the water was, but it was not real high. There was a small beach at the base of the ledge you described (which you can sort of see above the boats). The other picture is something an ancient race left there
At higher water I've missed the landing. Lots of differences between hi water vs. low water options to get off the water. In some cases you can't reach hi water camps at low water, and at hi water the low water camps are flooded.
