From the basin south of the peak, climb the obvious chute that leads to the notch immediately west of the East Summit. One pitch of 4th/low 5th-class climbing gains the summit.
Its hard to believe that this line hasn't been climbed before, but the FA teams for the SW Face and the West Chute must have been interested in harder lines. I thinks its very likely that they used this route as a descent.
Return the way you came. This is also the best descent for routes reaching the East Summit.
