(This is line "C" in green on the map of the spring boulder)
Sit start on the short crack, side pulling it from the left. toss up to the perfect left hand pinch like jug. make a righ hand move to an almost identical one. raise up your feet and make a large dynamic move to the far right top of the boulder. the right hand goes to the level spot where the water seam ends at the lip.
pull down, throwing your left hand up and over the top, matching the water seam with your left. find the best place to crimp on it, and mantle up over the top.
A chalked up top out to seam-stress
