In reply to TCROOKS:
I did the Glen Lyon 4 on Saturday with a friend who was hoping it would count as a QMD for his logbook, but there was a lot less snow/ice than we thought, and he reckoned he couldn't use it. We never even got close to considering use of crampons/axe
More snow has gone since then, so I wouldn't think you'd get anything in the southern part of your big area, no idea on conditions further north though
