Spruce Hole Bog
The Spruce Hole Bog, locally known as Spruce Hole, is a complete ecological community occupying a true kettle hole in the town of Durham, New Hampshire. According to the National Register of Natural Landmarks: "It illustrates characteristics of a typical sphagnum-heath bog, localized in a specialized geologic setting." It was designated a National Natural Landmark in 1972. Spruce Hole is located two miles west of the town center of Durham, and is owned by the town which has conserved 35 acres around it. It is reached by a woods road off Packer's Falls Road, and despite the name the surrounding forest is mostly white pine, hemlock, and birch.
The bog is also adjacent to the Oyster River Forest, a permanently conserved 172± acre parcel owned by the Town of Durham.
