Your typical Castlewood Canyon route. Pull on cobbles, incuts, and small pebbles up the arete. This arete lies on the north end of the Project X Wall, about 20 yards past where the giant boulder ceases to follow the wall. Tip: look for the incut for your left foot above the first bolt.

2 bolts to a 2 bolt anchor. TR setup might be a bit dicey.
Whoops. Forgot to this in the last comment. There's actually 3 bolts to a 2-bolt anchor (just in case you were planning to hike all the way to Project X wall with only two draws to do this route only ;-)
There is not really one distinct crux IMO on this route--it is pretty consistent throughout so take care in clipping the first bolt. Like Myke said, very typical CWC route: short, steep, pockets, cobbles, balance, fun.
