We started at diamond head at 10:30pm and then I slept on the bench in front of the heater at elfin for a few hours. Weather got worse, we skiied to Opal cone, then retreated. We probably could have gone as one other VOCer was setting track about an hour ahead of us on a solo day trip across. He left a pair of running shoes at the canadian tire in squamish so he could "run" the 16km back to his truck at Elfin parking lot .
