Ithaca, NY: Cornell's Old Growth Forest
The forest is called the Fischer Tract and it is on an unlabeled path leading away from Route 13 in Newfield, New York. It is a special plot of old growth forest that has been protected and by nearby Cornell University.
Technically what you see in the picture isn't really old growth since I was standing at the edge of the plot looking back towards the way we entered the forest, so the most of the trees and underbrush in the picture are much younger.
