There's a shuttle from Winthrop to Mazama in January and February, allowing people to ski one-way across the upper Methow Valley. I'm planning to go out and ski the Methow Community Trail. It's 30 km, about 20 miles. I have a hydration belt that might hold enough water to last 10 miles if I start out well hydrated.

Anybody in here done the MCT before? Is there any liquid water to be had along the way?
