This is another photo of "Dan's Secret Anchorage" aka Cardoncito.
The depth is about 45' - 55' right at the center of the entrance, but is 25'-35' in the center for almost the entire length of the fjord-like bay. It tapers down to 8'-15' along the edges, right at the base of the cliffs. Obviously, as you come up to the beach at the end of it, the depth drops to 0.
In the 2nd photo below (taken as I walked up the hill to take the 1st photo), my boat is the one on the left.
