Treehenge is a place at Ft. Hancock in Sandy Hook, NJ where the sun sets precisely through a small opening in a young tree, but only on or around the summer solstice. In this gallery are shots of Treehenge on the summer solstice over 10 consecutive years. Watch young Treehenge grow up over the years. You can also see Treehenge on the autumnal and vernal equinoxes, and on the winter solstice - to see the difference as to where the sun sets.
