After looking at the pit, we returned to the trail and soon we were at a camp site.  Well, once upon a time it was a camp site.  Now it's just a clearing w/a rotten picnic bench and some other junk.  As we looked around it seemed to be built on a number of walled terraces.  I bet this "camp" and it's terraces is related to the two tunnels on either side of this ridge and to the Secret Site one ridge away.
