Teal Brook flows through this property and a vernal pool, red maple-hardwood swamp, and part of a spruce-fir swamp are found here as well. Most of the land is covered with "northern" type forest, including some spruce-northern hardwood forest and spruce flats, forest types known primarily from the Adirondacks. A spring is found on the property as well as a cistern and an abandoned family cemetery dating from the early 1800s. The most unusual plants found on this property are the Rattlesnake-plantain, Goodyera tesselata and the Bog aster, Aster nemoralis.
