The crux for me was near the start, getting up above the gap and into the crack.

On Another Man's Wound

If you are on top rope climbing toward the bolts, the top is very thin.  There are good holds to the left in a triangular recess, but you'd be at risk of swinging from there. 

  The start was a bit nervy, as you step across from the block to the face.

Start just to the right of a bolt 10 feet up, and climb on tenuous slopers past the bolt and left until you reach a thin crack. Follow this crack up and right as it widens until you reach a false topout. Continue up more slopers to gain a second crack which leads to a bolted anchor.

Leftmost line on the Clamshell Wall. Heel hook the opening crux off the big boulder, clip the bolt (stick clip might be advisable, though you can place a small cam at the lip before beginning). Move left on easy ground and blast to the top up a clean strip of white rock. Second mini-crux near the top.

The rightmost route on the clamshell wall before the scramble-up section. It’s often wet after rain. 

The line in between little necky and dirtissima

This route is also known as Little Neck-y.

 Start far right, edging left; after 10 feet, climb directly up the obvious crack another 15 ft, after a small tree, ascend directly to the route's crux well above the tree (60 ft). Pull up and over a small bulge, finding many slots for good pro placements and jugs all the way to the top, where a final difficult move awaits. Interesting holds on "clamshell" rocks, requiring much open grip work. Crack is on-width most of the route, making the middle section more like 5.5 or 5.4 climbing.

This is the tall, mostly grey face, with many horizontals that resembles the Trapps. The left end of it starts 7 ft above a large rectangular boulder. There are about 8 distinct lines that mostly follow vertical cracks/grooves and 3 bolted anchors at the top, though these may not be in the spots that get the most traffic. Two are on the left, one ledge system below the top. The other is on top at the right end.
