Half Slabba' Ribs

Start standing with double undercling to the left of the tree at the bottom of the problem. The feet are tough, and it's an interesting climb, since it's about half vertical and half slab & the holds are varied with no real jugs until the second to last move. Although it's a bit sharp & the landing is slightly sketchy, I think it's a great city boulder problem! (You can definitely setup a TR for this one as well, solid trees at the top.)

There are 2 crux moves: the first is keeping both feet on (slim footholds) while you match on the first move's diagonal ledge. The second is a right hand crimp halfway up. Once you get it, you can settle your feet high, and reach for a nice right hand pocket.

This is on Hemlock Hill in the Arnold Arboretum just east of Chompasauras and Horney Toad.

Crashpad & a spotter!
