Start on the boulder in the middle of the wall. Pull on, and make thin face moves for 40 feet. then, step up and left into a powerful bulge that offers some relief with tufa stemming. Take it easy on those tufas! pull up the tufas to a sharp pockety section, and clip the anchors. Lightner's guide lists this as 'one of the reasons you came to Siam.' I agree!
Location
starts on top of the boulder in the middle of the wall. there are two routes that start here, I think medusa's lover is the left route (the right route was not in the guidebook, but it looks good as well.)
