As I studied the topo of the area, I realized that there were many other possibilities in getting to the top of the Drum HP besides the way I went up. This was my second choice. Granted, I have not done this route, but it might be an alternative for those who don't want to drive up the high clearance road. I noted on the register that one of the signees mentioned he was going back down via a northern ridge after he had come up from the west. It might have been this route. FWIW
