Thompson Pond, National Natural Landmark lake in Pine Plains, New York, US
Thompson Pond is a body of water covering about 75 acres located at the base of Stissing Mountain and serves as the source of Wappinger Creek, which flows to the Hudson River. The entire preserve spans roughly 500 acres and includes various habitats such as wetlands and forested areas surrounding the water.
The pond formed approximately 15,000 years ago through glacial activity as a kettle hole and received designation as a National Natural Landmark in 1973. Recognition came due to its exceptional characteristics as a calcareous bog system, which is uncommon in the region.
The preserve represents a collaborative effort between local communities and conservationists to protect a rare ecological area where visitors can observe specialized bog plants and watch birds in their natural surroundings. People come here to experience how nature functions in this specific landscape and to understand the relationships between water, soil, and living things.
The property features multiple hiking trails around the water, including a wheelchair-accessible path that leads to an observation point. The best time to visit is during bird migration season, when a wide variety of species pass through the area.
The bog area supports an exceptionally high number of plant species and serves as a critical stopover for migratory birds undertaking long journeys. This concentration of biological diversity makes it a place where nature observers can discover a remarkable range of different life forms in one location.
