The Black Spruce Bog is located near the Forest Headquarters. The area was probably formed as a “sink hole” after the last glacial period, by the melting of a large block of ice that left a depression about 40 feet deep which filled with water. Gradually plant growth filled the area from the edges toward the center. The site has long been recognized as a unique natural area and represents one of the few such plant communities of its type in Connecticut. It is also noteworthy that within the bog, individual specimens of Black Spruce and Larch have achieved a stature rarely found in the state. As this plant community is considered an outstanding example of a late-stage peat bog, it is a popular site for educational activities and scientific purposes and features a trail and boardwalk placed to minimize damage to the bog.

Mohawk Mountain State Forest in Connecticut offers an expansive view of the rugged terrain in this area from a 1,683 foot peak. The two main attractions of this State Forest is the 1,683 foot mountain, and the Black Spruce Bog which offers a unique plant community for the area.
