As you reach the final pitch above 14,000', it is easy to lose the trail, especially if there are snowfields. To follow the standard route, stay west on or near the ridge. We meandered a bit to the east and achieved the notch in the ridge that is visible from the basin floor, then scrambled west to the summit, quite enjoyable -- and we avoided the snowfield.
Also the trail is strong and well marked with cairns beyond the Bear Lake turnoff -- this is a Class 1 trail climb until the last 400 vertical feet. Roach's route description would make it appear that there is routefinding before this, but it is no longer the case.
