The group: 4 very fit hikers/scramblers. We're all moderately experienced snowshoers, and are comfortable doing 20-30 mile dayhikes in the summer and 15-20 mile/day backpacking trips. We all also have some amount of winter mountaineering experience, my hiking partners on Shasta (Red Cliffs/Heart Lake route) and myself on Mt. Washington (O'Dell's Gully) in NH. We're all extremely safety conscious and 3/4 of us have attended Avy classes.
We've been to Pear Lake in the winter before, so I know what the trail does and does not look like in snow. My questions are about the last 1.5 miles to the peak:
It appears that there are two possible routes from Pear Lake to traverse to the East side of the ridge descending from Winter Alta:

The above picture is from Leor Pantilat, h/t to him. The corresponding Strava info is here: http://www.strava.com/activities/38207520 Given that he chose the lower route on return, I assume it is probably preferable to the gully that climbs directly from Pear Lake?
My other question is the rightward traverse after traversing leftward underneath the cliff bands, on the way to the final ridge towards Winter Alta.
Pantilat's route appeared to avoid the ridge entirely until the summit, but the waypoints I found here access the ridge directly at the low saddle east of winter Alta: http://explorepangea.com/Activity/Backc ... rAlta.html
Would this be likely to develop a cornice at the top or anything else sketchy? This is the part of the route that gives me the most cause for concern.
Any and all thoughts appreciated.

Michael
