Perk has it right. The headwaters area offers about the best for all-around terrain. You have meadows and small hills around the base of Galena Pass and the further you get up toward Vienna Mine, the mountains get bigger and the snow gets deeper. The area can be tough if you don't know where you are going. I would offer to help out, since I will be up in the area this weekend, but I am already committed to going out with several buddies in an undisclosed location somewhere to the east of Stanley. Like Mike said, some of the locals don't like to let out the secrets spots.
Speaking of that, Mike; How has the Wood River Valley been this year? I got one Clayton ride in over the New Years and it was great. Mill Creek and the Yankee Fork actually has more Snow than Vienna so far and the locals are eating it up. Quite a year so far.
