Fossil creek (actually Grays River...FC name drives me freaking nuts) should be an easy one. Look at the largest stands of timber, the steeper ground, with canyons that don't have roads in the bottom. I'd hit the back of the 6200 system in the west fork grays, the 7050/7340 into the south fork grays, and even the upper 7400, 7700 into I think Johnson creek. The upper end of the east fork grays is getting grown up, so there are probly some good ones hiding in that corner of the farm as well.
