Interesting stuff. I kind of assumed everything pre-1952 was AGC. I bet the 11.1950 storm was closer to 40” at the current location, but that’s lost to history.
Sticking a ruler in the ground once a day downtown is going to give you a much different total than religiously clearing your snowboard at the airport. This year’s 14.5” probably aligns well with a single digit year pre 1952. Aren’t many that have been leaner when looked in that context.
I *do* think the current location better represents where the population actually is. Of the metro areas ~2M people, I’d say 75% of those live above 1000’. Would pretty severely understate things if someone was out in point state park measuring snow.
