This tall problem starts on a vertical skinny hold and moves up into sidepull crimps. There are 3 options for sidepulls and use these to get to a slot in a crack. From the slot climb straight up to a heady top out. I think its okay to use the roots at the top to finish since there's no exposed rock on top. Be careful because they are loose. 

  WARNING: be mindful of your fingers in the slot. If you take a fall you have to consciously pull them out as you're falling or else they will get stuck.

Start on the lowest part of the foot wide shelf. Figure out where to put your right foot to get off the ground and work your way left using heel hook and through a careful hand match till you reach a pretty good left hand pinch. From her figure out some weird positioning and go for the notch at the lip. Slopey top out right.    ( If you have the NE Bouldering guide i believe this lists as Army of Ants V2. V2 this is not unless there is something I'm majorly overlooking, or if you use the cheater block next to the start. I'm tossed up on what to give it for a grade so take it with a grain of salt. This is my best guess based on a few similarly graded routes I've done in the notch, combined with the little info I've been able to dig up. If you have better info like Name, grade, FA let me know. I just wanted to post it up since its rad.)

This is an interesting line that runs up the arete just to the right of penumbra. The sit start is hard enough to be interesting. After gaining the obvious jug hold on the arete you can either mantle and step up and right or continue up the arete. The step up and right continues to the top on lower angle but balancy VERY high moves. This is the only line I've topped out. The proud line follows the arete all the way to the top - which can be top roped (hard - 5.12?) but can't be exited due to massive vegetation.
