I took the East Snowmass trail for approximately 4.5 miles until I passed an open space with a clear shot all the way up to Willoughby's (false) summit. This came almost immediately after a sharp switchback that dropped into and ascended out of a small stream drainage. From this spot I took Class 2 grass to the ridge and then continued up grass to the last few hundred feet which were steep, extremely loose dirt and talus. Pretty unpleasant, this section was Class 2+. Once on the north ridge proper it was an easy Class 2 walk to the true summit.
