Spruce Hole Bog
Open-knowledge reference entry
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, United States. 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 2 miles (3 km) west of the town center of Durham and is owned by the town, which has conserved 35 acres (14 ha) 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 (70 ha)+ parcel owned by the town of Durham.
“Spruce Hole Bog” enters the record as open-knowledge reference entry. Crown Archives preserves that source wording while asking what Spruce, Hole and Open-knowledge can confirm, complicate or overturn.
Why this record matters
“Spruce Hole Bog” is worth following because a concise public description often conceals a longer documentary argument. Here, Spruce, Hole and Open-knowledge provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 6, 2026. The linked authority identifier is Q7581415. Authority coordinates are 43.126, -70.968. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1972.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
