This cliff is on private property, bordering Townsend State Forest, about 100 yards from the New Hampshire State Line. The photo was taken at the very close of Autumn, just a couple hours before the Winter Solstice. Unseen, there is a barbed wire fence between the cliffs and where the photographer stood. Just a few minutes prior, the ATV riders had vacated the area before the photographer arrived on foot.
The temperature was just above freezing. There was a light snow falling, but melting as it touched ground
