I am guessing the lake is Skookum Lake. I drove there many years aog, but I've been wanting to hike there.

As for the other "trail", that sounds like an expert class question, so I'll pass.

Well, now I'm guessing. Dickey Lake. 549 Trail.

Donovan wins the prize.  It is Dickey Lake.  I went there a couple years ago to investigate for a backpacking trip, but there isn't much of any camping around the lake.  As I recall, the trail was rather brushed in too.  It is a very short trail between Bull of the Woods (550) and Pansy Lake (551)....OK Donovan, now it is your turn to post a picture of a trail and let us guess....This will be a good one, I'm sure.

Since I already know where the picture than Don posted is from, I'll give a little hint.  It is in one of the newly designated wilderness areas.

This is my submission.

This is the view at switchback on the mystery trail.
