I guess it could be the upper part of Hackett Rock...it looks more like this right now (though it's more dug out than this picture shows):
This is the lower portion of Hackett Rock, again more dug out now than this picture shows (at the base of the rock):
I should have taken more pictures when I was down there, there's not that many that I can find online. Still a bunch of trip reports from before the fire...
Scott, don't you remember who that was you were pulling out?
