Southwestern county, part of the 1794 Treaty of Canandaigua that extinguished most Seneca nation land rights, is shown here not long after its incorporation in 1817. Remnants of Senecas land are visible as the Cattaraugus Reservation (at upper left) and the Allegheney Reservation (alongside the river). Although the county's population still was sparse we see townships laid out already on Burr's map--particularly surrounding Olean, whose location on the Allegheney River made it a desirable trading post. Along with existing villages, county roads, and water features (the legend mentions stage roads, mills, forges, and churches, but none appear on the map).
This item consists of Burr's county map and a cropped version focusing upon the Allegheney River, the latter used for the
Watersheds exhibit.
