Begin matched on a blocky corner hold featuring a left hand crimp and a right hand sidepull/pinch on the right side of the wall. Then make a left hand cross to a good block. From there, proceed out to a good, right hand sidepull, and come out left to a slopey lip and up to a big, finishing jug. Due to the giant finish being unstable, there is a possibility that it could crush you should it fall. With that being said, use caution if deciding to finish on it or finish on 2 small jugs right by the left slopey lip and original top.
Hobo Cave is located near the bottom of Flagstaff trail. You can park at the Gregory Canyon trail area. Go up the Flagstaff trail, Hobo Cave is an obvious, black cave off to the right of the trail. You may be able to find a little path made by climbers, or bushwhack your way up (if this doesn't make sense, look at the location on Hobo Cave).
2 pads and a spotter should do.
