History
On March 25, 1800, Greene County was created by the partitioning of Albany (360 Square Miles) and Ulster (270 Square Miles) counties, producing a county of 620 square miles (1,600 km2).
On April 3, 1801, 90 square miles (230 km2) of land was transferred from Delaware and Ulster counties, raising the total area to 710 square miles (1,800 km2). This transferred Prattsville, Vly Mountain, Halcott Center, Bushnellsville, Highmount, Shandaken, Lanesville, and Pine Hill within Greene County.
On May 26, 1812, Greene County lost 20 square miles (52 km2) to Ulster County, lowering the total area to 690 square miles (1,800 km2), reassigning Pine Hill, Highmount, and Shandaken to Ulster County.
On April 15, 1814, the county borders were re-surveyed, and the line adjusted with no change in area.
