Tall slab beside Yellow Arete. I start it under the bulge and pull over to the crystals and work up to the reachy crimp at the top.
Location
This route is located to the right around the corner from Yellow Arete. I believe someone has added a line between Yellow Arete and this route, don't know the name. Yello Mon is located to the right but shares the same top out, as far as I know.
From Yellow Arete working right...Yellow Wall Slab - V4, Yellow Submarine - V2 and Yello Mon - V3. There is also a traverse (right to left and up Yellow Arete) Yellow Wall Traverse that is V6.
Fun problem with a committing move going to the top (if I'm thinking of the right problem, last slab before going around the corner to Yellow Arete?) A gimme at V4, there are much harder v3s at Boat Rock.
