I'd call the eastern Aroostook terrain gently rolling rather than flat - flat is what I saw when the grandkids lived in DEC. Once one gets 20 miles N and W from Baxter Park, the hills in NW Aroostook top out at about 2,000' and the general elevations outside the river valleys are 1,000+. However, even those hills manufacture some snow. In 1976-77 when I recorded atleast "T" for snow on 82 of 90 days in DJF, I think Rocky Mt - 10-12 miles NW from Allagash Village - had at least some accum on every day I was there checking the loggers, which I did about 3 days/week. Probably 250"+ there that snow season, compared to the 186.7" I measured in Fort Kent. A few years later (Dec 1983) I had a messy SN+ to RA to SN dump 12" on Dec 5-6 and the Rocky area had 18"+ of clingy SN that led to major windthrow losses. Then the mod/hvy ZR on 15-16, which produced a 3" crust with 1.90" LE at home, brought 10-12" of SN/IP at 1,400' near Rocky Mt. That was the winter when we couldn't do boundary maintenance because all the blazes were under the snow.
I've seen budding trees.
Male quaking aspen buds usually begin to swell in Feb, red maples a month later. Those species seem about in line with the averages. The geese did return to Belgrade Stream near the bridge on Rt 27 on 3/9 compared to 3/20 last year. The average lies between those 2 dates.
