Very nice rockclimbing above the snowpatch - Pity you have to get there, and get off somehow. Accessed via Banks range traverse (relatively serious in it's own right). To gain the snowpatch, it might be better to follow the large crack system up after p1, rather than trend left (with a rap), as the rock below the snowpatch is loose and prone to rockfall.
The great corner is a deathtrap since the top fell off. If descending by rapping into it and climbing out to the East Peak, expect every manner of loose blocks & dirt, to a steady accompaniment of spontaneous rockfall. The ridge doesn't look flash either but it's hard to imagine it being worse...
