Eastern Aroostook looks like the Midwest but with more hills, and the Downeast accent is rarely heard there. The St. John Valley is surrounded by decent size hills, but the major difference is culture, as 90%+ of the people have French ancestry, some from Acadia and some from Quebec. One frequently hears French spoken, though it's significantly different from that spoken in Paris. West of Route 11 is mostly commercial forest land with paved roads becoming gravel logging roads a few miles west of that highway. There are significant hills in that area, with Deboullie probably the most rugged area - elevation tops out near 2000' so far less than Greens/Whites but also far more remote.
Winter. The latitude matters…northern Maine is a different area.
Our 1973 move from NNJ to BGR, 390 straight-line miles and nearly 4° latitude, meant a significant change in climate. Three years later we moved to Fort Kent, 170 miles and 2.5°, and that climate change was at least twice as much as from the earlier move.
