"Obtuse" starts to the right of the tall Ponderosa Pine in front of the boulder.
Start with your left hand on a far away sidepull, right on a pinch in the crack. Both feet go to the right of the crack. Stand strong on the feet and reach high with the left hand to the sloper. Pop your right hand up the crack, then move the left hand onto a higher sloper. Heel hook and move your right hand onto another bad sloper, then pull up to a jug.
I got the first ascent of this improbable looking line. Dave Asscherick and I tried it one day and thought it was going to be V9! But, surprisingly it comes together rather nicely and a lot easier than you would think upon first glance. I think it's cool that this problem is all slopers and the problem immediately to it's left, Isosceles, is all crimpers; two problems right next to each other, completely different in nature.
