The Sacondaga River flows through a narrow valley through the southern part of the town. Its channel is narrow and it is navigable through the town.
The first permanent settlers were Phineas Austin, James Thomas, Dyler Perry, and families named Clay and Bond.
The first religious meetings were held in the barn of Peter Van Vleck around 1801. The first church (Baptist) was formed in 1809.
