Fun route to climb as an alternative to Double Cross if you're waiting. You can even top rope the chimney to the left if you don't have gear to climb it.
Forjan and I decided to climb the day after it snowed in J-Tree. The temps were in the 30's when we arrived. It's a nice climb once you figure out the sequence from the roof to the arete. This climb was not in my Vogel J-Tree book, so I colored it in myself.
Good moves over the roof to an arete/buttress that I would not want to fall on.
