Sutton on GoogleMaps looks to be located between say 400m and 900m (really might be 850m) in elevation. That equates to 1,300ft to 2,900ft in elevation. That's a significantly lower elevation for a ski area. A 2,500ft snow measurement probably describes a good bit of it to be honest. There is a non-noticeable amount of snowfall possible on average between that and above that. All else aside.
