Big lake with mountains next to it on one side= Squam. And to be clear, it is very inaccurate and exaggerated. But assuming it isn’t mirrored, this would be looking roughly towards the northwest with the sunset on the left, and Red hill being the closest hill on the right, the largest mountain in the back right probably being Whiteface, and the sliver of water just to the left of what may be Red hill would be Kusumpe or Intervale pond. Directly above that pond may be a dramatized version of the Sandwich Notch, an old road with historical significance that used to be the main access to the White Mountains in the 1800s.

A long time ago there used to be a well-known school/farm/mansion on a prominent hill in center harbor overlooking the lake. This view could be from there.
