Don't know your ages... but I need 8 hours to reach the top.
If I have to use snowshoes, I need still more time.
I've made about a dozen climbs... most were fun attempts
just to see how high I could climb during the day.
I've been to the top twice, into crater (but not summit) 3 times.
I have no winter climbing experience.
Like I say... weather and snow conditons are king here. If I don't like it,
I'm turning around. Any climb is a good climb, summit or no summit.
Would you like to try a get-in-shape pre-climb beforehand?
A 11pm departure seem agreeable to me. That'll put me on top at dawn (7am).
