Were you up there later that month? Farther east at Eustis, 1,260' asl, March 22-24 brought 34.5" - they had 64.6" for the month despite only 3.3" from the 5-7 storm. BPL was finishing a timber harvest on the Redington public lot (5 miles SW from 'Loaf summit) at 2,500+, with the last load coming out just as S++ arrived - probably a 40-spot there. 16" paste at my place.
I got 26" in 2016-17 which was the biggest since we moved into our house in 2013. Seems like 30+ is a big hurdle
I've been interested in wx since the Jan 1953 ice storm in NNJ and the biggest storm I've seen over those 70 years (yikes!) was 26.5" at Fort Kent in March 1984. 30s are rare most everywhere.
(Note: Farmington co-op reported 40" for 12/6-7/2003. We had 24" and were at church 1.5 miles from the co-op site as final flakes fell, and the snow there looked much like the snow at my home. 30"? maybe. 40? slant stick or in a drift.)
