The PG13 rating come from the potential fall when clipping the first bolt. If you fall its about 15 feet down onto some awkward boulders with some nasty leg breaking holes. luckily its 5.7 and its hard to fall. crux is climbing the arete mid way, not much of a crux but is sustained and tough for beginning climbers. belay from the large boulder below the climb. either rap down or scramble across boulders. There is a spot where the belay boulder is almost sitting on the boulder next to it, you can place a #9 BD hex if the belayer is lighter than the climber to prevent getting pulled off.
this is the next boulder down trail from no fat chicks. the trail drops you off at the top of the climb.
4 bolts to anchor, for anchor set up sling the loose block (looks kinda sketchy but it's heavy and in a good position) and clip the one bolt.
