As with any ski area anywhere, it is impossible to give you the conditions so far in advance.
That said, Vermont typically receives their highest monthly snowfall during the month of March. Snowpack is typically the deepest of the season and the trees are typically in the best of shape.
Keep in mind though that this is the east coast we are talking about and it could be anywhere between thigh deep powder to bulletproof ice, or worse yet, grass and rocks.
