This route is located in a SW facing alcove just south of the summit tower. If approaching from the west saddle of the third flatiron, you will walk most of the way around the Green Thumb to get here.

The vertical crack in the back of the alcove is Green Crack (5.8+). Climb the crack, short but sweet. Rap back down from a small tree at the top. I would give this route 3 stars if it wasn't so short.


Standard rack to 3".


....Alternate descents include walking right to a large tree (single sling and no rings as of 10/21/02) or further right and down to two good bolts (the top of Zimbra I think). Oct 27, 2002
I'm going to give this route 2 1/2 stars even though it is short. I also found it more difficult than the neighboring harder-rated climbs Diagonal Finger Crack and Green Corner - both of which are also excellent routes. All in all G. Thumb is an excellent spot to climb, well worth the hike in. Oct 17, 2005

Fun route as a warmup to be followed by other climbs, but it wouldn't be worth the hike to do just this climb.

Small stuff for the start which, for me at least, were the hardest moves. Then killer dihedral climbing to a very small tree belay. I was able to backup a TR with a horizontal crack a few feet above the tree. The tree seemed kind of small to me, so tread lightly on rappel. Apr 6, 2013
