Brief report:
My friend Luis and I climbed the left couloir while Pavel and Misha were getting on the right couloir. It snowed lightly all day and it was butt cold: temperatures hovered anywhere from single digits to lower teens. However, the ice was pretty nice. We got a late start. Started the first pitch at 11:30am. We skipped the summit (short daylight, blowing snowing in your eyes and cold drove us out) as we topped out just before 3pm.
