A Side Crack 

Not sure of the name, though it's pretty fun.
I found it randomly last summer.
The crack is analogous and goes right through the whole block, it's kinda funny cause you realize that the whole smaller block is just free standing there off axis. Amazing it doesn't just fall over you know? Apon closer inspection you can see it is cammed in there as the crack tapers narrower at the bottom.

I think 5.9 is pretty accurate.

I figured it was a good name since it continues all the way thru to form another route (what I call B Side). I've been climbing this thing for about four or five years and I'm sure plenty of others have enjoyed it for even longer.
