B Side Crack 

On the right side of the photo you can see another crack, I thought it was fun practice for off widths and chimmneying (if you stay out of the depths that is).

Fist jams, heel toe, chicken wings, inverted arm bars, thigh caming and chimney variations can all be used. More then one way to skin the cat so to speak.

Also there is a few other crack problems around. One is probably 5.6-5.7+? which liebacks a flake. Another is a real highball we did with 3 pads at about 5.10? Goes up a dihiedral with another crack/seam on the right and a large chockstone atop that must be past. We didn't want to go strait up over the chock stone so we transfered to the right crack near the roof/chockstone and passed it lightly on the right. Probably 25-30 ft.

There is more then that too if you have the means to get down off a giant block (a rope and someone to counter weight it), and a bunch of pads (maybe 5+).

I've climbed that problem on the right too, pretty fun ow practice. The 25-30 ft. one you describe sounds like another one that I've done but with a rope. I don't mean to down grade it but it didn't feel like 5.10 to us. I'm sure it felt that hard not being roped up and getting pretty far off the ground.
