Duanesburg is a town in Schenectady County, New York, United States. The population was 6,122 at the 2010 census. Duanesburg is named for James Duane, who held most of it as an original land grant. The town is in the western part of the county.
According to the United States Census Bureau, the town has a total area of 72.0 square miles (186.6 km), of which 70.8 square miles (183.3 km) is land and 1.2 square miles (3.2 km), or 1.74%, is water.
The town consists of mostly wooded hills up to an elevation of approximately 1,400 feet (430 m) above sea level. Most of the town was cleared farmland until the late 20th century. After this point forests grew to cover 60% of the total land area with a canopy higher than 40 feet (12 m). The forest is primary composed of poplar, hemlock, oak, maple, white pine, and balsam fir. The maximum tree heights in Duanesburg are approximately 80 feet (24 m) high.
The town is the source of the Normans Kill and of Bozenkill Creek. These creeks drop over a series of rapids and waterfalls cut through shale and sandstone rock beds. Christman’s Sanctuary highlights some of this topography.
Most of the soil contains clay, significant loose rock, and/or shallow depth, therefore making it inadequate for a large farming industry. There is a significant amount of swamps at high and low elevations in the town due to clay soil and past glacial activity.
The town is unique for its east-west oriented drumlins formed during the last ice age. Most drumlins (oblong hills of glacial sediment) in New York State are north-south oriented.
Due to its higher elevation and position, Duanesburg provides a view that extends as far as southern Vermont, the Adirondack Mountains, and the Catskill Mountains.
US 20, NY 7, and Interstate 88 pass through the town.
Part of the south town line is the border of Albany County. The rest of the south and part of the west town line is the border of Schoharie County. The rest of the west and part of the north town line is the border of Montgomery County.
