Is there a spring nearby, behind you?Don2
Well, there was a rather wet area behind me as a matter of fact. I didn't really notice if it was a spring though. I'll have to explore it more thoroughly next time I'm in the area!
Are you on the Hillockburn Trail on the eastside of the South Fork of the Clackamas or whatever they call that trail? I have been on it once from the top down, not from the bottom like you guys have been exploring it.
Don
Yep, you've got it. We didn't make it too much farther after crossing that wet area Donovan mentioned.
Your turn! 
I guess I should check this webpage more often. This photo was taken from a current district trail.

That looks like a Cripple Creek kind of a mess.
I think there are a couple of sizable areas of laminated root rot up there.
