The smaller topographical nuances are always interesting. I would guess latitude more than elevation is what gives the N side of Greenfield more snow than let's say Deerfield but my being 200' higher than downtown Greenfield does sometimes make a difference of an extra 1" or whatever. The bigger difference seems to come with being in an elevated valley on radiating nights. At 400' in the tight little Green River valley I radiate as well as anywhere in SNE.
One thing about elevation that I have noticed out here is if you like snow, you have to go over 1000'. I have two different snow loving friends at @ 800' - 850' range in Bernardston and Colrain. Both of them wish they lived a little higher since they are often on the wrong side of the R/S line. My friend on Rt 112 in Colrain can literally walk a mile up his road to 50% more snow during some storms. That would drive me absolutely crazy. As it is, I am less than a 10 minute drive to better snow totals.
