These are the notes I took while driving towards Red Mountain Lake Trail from the East:
0.0 Turn West on Bulger Flat Lane.
2.1 Road curves left and narrows.
2.6 Pass "LIEN" private drive on your right.
2.7 Continue straight (vs left) at fork.
See a sign "ACCESS TO PUBLIC LAND" on your right.
3.1 Cross over a creek on a bridge.
3.8 Continue straight.
5.2 Continue straight at a 4-way junction.
See a red arrow painted on a rock ahead.
6.0 Road gets rougher and narrower.
7.0 Pass a hunters' camp on the left at a small meadow.
7.2 Road becomes steeper with many larger rocks.
Called "The Rockpile" by a local bow hunter.
I turned around and returned to the meadow to camp.
9.5 (approx) look for a road leading left to the unmarked TH.
