I just came back from spending the weekend there after a month's absence in New England. Conditions were great but yes, they were groomed frozen granular with powder on top. Unfortunately they had morning rain on Sunday so they will have to work at firing the snow guns to supplement the natural snow in the slopes forecasted for this week. However, the base is indeed deep, although the extremely heavy traffic areas such as the loooong green trails to and from Widowmaker have shown some thin patches.
Overall, the place has some great conditions for Mid Atlantic. I do hear that the resort will close for the year at the end of March instead of the previously reported April... We'll see.
