I've been fielding a lot of questions about Sneffels and Yankee Boy Access, so i thought I would post what I know. The official opening is May 1. I'm not sure how far it will be plowed, but I would imagine at least until the Ruby Trust Mine. If you go, remember that the plow takes all precedent!
Do Not Block the Road!!! Only park where the plow can get around you. I.E. not at the very end of the plowed road where they can't get around to plow further. There are usually adequate pull-outs in strategic locations along the way.
Enjoy the spring skiing and mountaineering! Cheers, CC
