The Big Roof area is the farthest little wall as you walk east and north along the trail. Yup, it's a big roof. This route is pretty sweet, if only for the intimidation factor. It starts on the sandy wall directly below the obvious big roof. Don't blow it on the first clip or 2 as there is a back-breaker rock that you started on. Have your belayer clip into the rusty bolt on the huge block on the ground. Climb up and trend a little right just under the roof and try to catch a little (uncomfortable) rest. Clip the next bolt while below it, obviously. The crux is pulling the roof. There is a definite sequence that makes it easier but it's still not easy. If you're shorter than 5'10" good luck. Maybe try levitation.
