OK, I'll jump in. 

This trail is in a wilderness, and it's a through trail.  Can you tell me both the name of the trail and the general location where the photo was taken?

Well, it doesn't look familiar to me, but I'd love to know where it is!

Is this a current district trail?  Or is this a lost/abandoned trail?

This is a current district trail, on all the maps, and has a number.   The location of the photo is not too far from a junction with another trail. 

Well, it reminds me of a spot on the Serene Lake Trail in the soggy bottom below Middle Rock Lake.

I think I know the spot you mean, but that's not it.  Too far north.
