This is at the upper end of difficulty for intermediate snowshoeing trips. We will target a pace that gets us up in 5 hours and down in 2.5 (through copious glissading, I hope). Priority is given to folks who were signed-up for my previously canceled attempts, but if you are not one of those people, you can still request permission. Crampons (and obviously snowshoes) will be required.
