Champlain Valley sucks for retention....I’m defining retention here as snow depth days vs annual snowfall. They have a lot of snow cover days because of a lot of nickel and dimes but they melt out easily. I know you already know this, but maybe I’m just super aware of it from back when I visited St Michaels college a lot back in the mid 2000s.
I’d leave ORH with a double digit pack and frequently there would be a junk 2-4” pack in the valley there after being buried most of the trip through MPV/Waterbury/Bolton and then it would go shit after Richmond. A few times during late season in March I’d go from a 10” glacier in central MA to bare ground there.
Despite that, I kind of see where you are coming from. I’d still think they would have a few better streaks given the latitude.
