Chatfield Hollow State Park

Chatfield Hollow State Park is a public recreation area occupying 412 acre that lie adjacent to Cockaponset State Forest in the town of Killingworth, Connecticut. The state park offers hiking trails, a swimming beach, trout fishing, mountain biking, rock climbing, and picnicking areas. Park attractions include 6.67 acre Schreeder Pond, Indian caves, historic sites, a restored water wheel, and a reproduction covered bridge. The park is managed by the Connecticut Department of Energy and Environmental Protection.

History
Chatfield Hollow was designated as a state park in 1949. It was developed in the 1930s as a Civilian Conservation Corps recreation area within Cockaponset State Forest. The CCC created Schreeder Pond in 1934 by building a horseshoe-shaped earth and stone dam across Chatfield Hollow Brook. In 1937, Oak Lodge was raised on the west side of Schreeder Pond; the lodge was listed on the National Register of Historic Places in 1986. A "from the ground up" restoration of the lodge was completed in 2017. The region where the park now resides was an important area for indigenous peoples. From the Paleo-Indian time approximately 10,00 years B.C. until the Final Woodland years which end in 1633, the area that Chatfield Hollow State Park occupies was important for fishing, plant gathering, and hunting to the River Indians of New England.[6] The Hammonasset people are recorded as being the first known inhabitants of this area. There are large granite rock overhangs where artifact discovery shows inhabitance long before the first English colonists settled in Chatfield Hollow. These rock overhangs are today known as the Indian Caves and can be visited by hiking a marked trail in the park. The three Chatfield brothers for whom the park is named arrived from England around the year 1639. [7].

Geology
The park's bedrock ledges consist of a type of gneiss called Monson Gneiss, a medium- to coarse-grained rock, light in color, mainly composed of plagioclase, quartz and biotite; trace amounts of garnet, epidote, magnetite can be observed in places. The park sits in a glacial valley, with steep declines on either side and an abundance glacial erratics. The erratics are smooth with sharp edges removed; the majority are composed of Monson Gneiss. Examples of other rock types can be found in the park, since erratics can sometimes be moved great distances.

Activities and amenities
The 825 feet Paul F. Wildermann Boardwalk allows visitors to cross an inland swamp without disturbing it. In addition, some 20 mi of hiking trails, including the blue-blazed Chatfield Trail, originate within the park and extend into adjacent sections of forest.
