Brilliant compression line on the Nerf Boulder! Start SD on the far left arete of the boulder (the same holds as Memento Low) with RH in a low thin slot, and RH on the knobby sidepull. Reach up left to the arete, and continue climbing the arete with face holds for your RH and the sloping arete for your LH. Great movement, great holds. Continue up arete until you encounter a HUGE jug, from here roll left onto the slab and continue up to topout on Memento. Not sure about the grade, but brillliant techy climbing.
