Very good detective work. Here is a shot from the top of Gunstock. At the top of the lift you are looking west and see Lake Winnisquam.
....and....from 1/2 way up Belknap Mountain, on a recent hike, here is Winnisquam to the west.
In FlyGuy's Aerial, Gunstock is the tall peak to the far right and Belknap is the second one over and is the tallest.
My place is up and over the Belknap Range in the upper left hand corner. It looks like there is some blue there but it is probably just fog rolling up the mountain!
Other details I noted in the aerial photo were the lay-out of Kingswood Golf Club in the lower left and the Wolfeboro Airport out on the neck.
