Interesting spire of quartzite on the north side of the mouth of Rock Canyon. It's in the same gully you use to get to Trilogy Buttress. Not very busy, so the rock's not polished. The slope along the base of the wall is about a 45 degree angle, so be careful not to knock too much rock down on your friends as you scramble up.
Also, FYI, if you continue up the slope past The Wasp, and stay to the right, there's a cool little crevice to play in. You can stem up into a hole in a ceiling which will put you back into the main gully. If it wasn't such a loose climb to get to it, it would be a really cool bouldering problem to play in. You can see the spot in the picture of Trilogy Gully below; it's the really dark spot straight above the spot marked as The Wasp.
Getting There
On the north side of the canyon mouth, use the trail immediately east of the water tank. Pass the first fork (where, if you went left, you'd go to Super Bowl Wall) continuing straight up the gully.
When you get near the base of The Wasp, there will be a steep scree to your left that you can follow around to the west side. (It's easier to go this way than along the dark rock that separates Super Bowl from The Wasp.)
