Sit down start on a cobbly ledge. Climb up and left on slopers to a horizontal seam. Fix your feet on good rock and pump for the big edge on top. Very fun.
From the road, follow the trail behind the Enlightenment Ridge campsite downhill past the campsite boulders to a fork heading left. Pass the fork and continue on the main trail for a second and look to your right. The first boulder is called Lizard Lips, right next to it is Flabby Cabby. Losing My Marbles is on the Flabby Cabby boulder, all the way to the right in the overhang.
Crash pad, spot.
