Mine workers drive all they way to the summit (theres a mine complex access up there). not sure if private vehicles can go to the summit but I's sure you can drive for quite a ways up before the snow starts to fly
Cool, thanks! I was thinking that may be a good way to access the Vasquez Peak / Mt Nystrom areas. I was up around there for the first time a few weeks ago... looks like a nice place off the beaten path to explore a little.
