Nescopeck State Park is a 3,117-acre expanse of forests, former farm fields, and wetlands stretching for about 4 miles in the upper Nescopeck Valley. The park is currently undergoing development of day use areas; an environmental education facility and campground are also planned. Nescopeck does not have any designated natural areas, but several wetlands have been included in special management areas. The park is located in the Ridge and Valley Physiographic Province near the boundary of the Wisconsinan terminal moraine. It contains areas of glacial till and other areas that were not glaciated (Braun 1999a and b; Crowl and Sevon 1980). Bedrock of the entire park is Mauch Chunk Formation (DCNR 1980). Beaver have been a major factor in shaping the wetland communities of the Nescopeck Creek floodplain. A series of present and former beaver ponds is present along the main stem of the Nescopeck and several tributaries. McMaster and McMaster (2001) described a series of successional beaver-determined wetlands in western Massachusetts that show patterns of development very similar to those seen in the Nescopeck valley. While these must be considered temporary or successional in nature, they provide habitat for several rare plants and other species.
