The plan is to do the Southeast Face and reverse the route.  It's described as the standard route in Alpine Select and I think a similar version of it is in Matt Gunn's book.  I don't believe the Australian Coulior will be in condition this year.  This is a mixed rock scrambling and snow climbing route that requires a broad range of climbing and mountaineering skills.  As a result the prerequisite for this trip is high.  I must know you and have climbed or mountaineered with you before.

It's a really fun route if you like a little rock and a little snow and a little this and a little that.   It's very good rock but there are several exposed sections, so we're going to bring protection and a light rope.  Ice axe, crampons, helmet, harness, and anchor material etc are all required.

The absolute maximum is 6... although the organizer will use discretion.
