I wasn't sure there'd be enough snow- a couple weeks ago I rode up here and it was frost-free. But it turns out there's plenty. I'm guessing 2 or 3 feet. I headed up the trail from Coll Alto and before long I was on virgin snow, no footprints or sci di fondo tracks. By the time I reached the Trail Junction where I planned to head back on the high trail I was exhausted. Definitely uses different muscles than road biking. I stumbled back to the car on the same trail I'd come on, in a snowshoe-induced stupor. Some food and a hot bath and I feel good as new. I will return soon.
