Really fun climbing. Don't know where the PG13 rating could possibly be warranted. Even the upper, 5.0 slab had a handcrack option.

I pitched this out as follows (after getting to Baseline Ledge, which is one or two pitches of 5.7 scramble but fun).

P1: Romped up the parallel cracks (5.6), then step left to a finger-sized crack for gear belay.

P2: Climbed the finger crack to some other harder moves as the crack slowly widens to thin-hands. (5.8, then easier again.) Angle kicks back and there's a great place for a thin-hand to hand gear belay on a low-angle ramp on a left-facing corner. Good place to stay in the shade.

P3: Easy climbing again, rings to hands to a bolted belay off right. (5.7, but mostly easy.)

P4: 5.0 walk with a fun hand crack to the trees.

Tried to link the last two pitches with a 70m but came up short and downclimbed the crack. Kevin McClane pitched this out in 3 pitches in his guide, is it possible to go straight from the finger-crack to the bolted anchor with or without a 70m?

From P 3 belay (little ledge) through the awesome fingers/hands long moderate section you can stretch a 60m to a nice comfy ledge, but save a #1 & 2 C4 for the belay.

Got lost on 2nd jungleering pitch but just keept going up and to the left.

Well protected, not PG13. If you notice bad wind in the parking lot you will be in for an adventure on this route. After climbing a very windy 190 feet of 5.6 wide crack you step left into an amazing finger crack that is truly on the edge of the apron. The wind RIPS through this section of the climb pulling helmets off, chalk bags sideways, the rope, and of course you. That being said, it's quite the windy adventure if you get it on a day like that!

I'm also -1 on saying this is PG13. very well protected.

This route was great for a post rain day. Minus the first 2 pitches, the rest dry quickly. The second pitch was very wet the day after a rain and there was definitely some cussing happening but it was fine. Just wear long pants to wipe your feet off on. You know you are at the start of the route because you are literally climbing the first pitch through trees and dirt. There is a fixed line to the right.

You can string this together with Elaines crack (5.10a) and then memorial crack (5.9) for 8 pitches of wooohoo! that tops out at the top of the buttress. 5 rappels (not 4 like the book says) to get off or hike off. The 2nd rappel is a rope stretcher so don't forget to tie knots. The rappels go near the base of the climb so you can leave your pack.
