24/7 Trauma and Biohazard Cleanup in Keeseville, NY

Keeseville is a hamlet and census-designated place that straddles two counties — its northern half lies in the town of Au Sable in Clinton County and its southern half in the town of Chesterfield in Essex County, with the Ausable River forming the county line through the middle of the community.

Keeseville was originally called Anderson Falls by its New England settlers, and it was renamed around 1812 for the Keese family, early settlers from Vermont, and a local manufacturer and businessman.

The Ausable River's water power made early Keeseville an industrial hamlet devoted to lumber, iron processing and milling.

Keeseville was home to New York State's first rolling mill, built in 1816 by the Keeseville Rolling and Slitting Mill Company.

The Ausable Chasm Horse Nail Works produced about two tons of horseshoe nails a day and operated from 1863 to 1925, making Keeseville a center of the horse nail industry.

Keeseville was an incorporated village from May 1878 until its residents voted 268 to 176 in January 2013 to dissolve the village, which officially ceased to exist on December 31, 2014.

As a census-designated place, Keeseville had a population of 2,931 at the 2020 census; the smaller former village had counted 1,815 people in 2010.

Keeseville has an unusually rich collection of historic bridges and buildings — the Stone Arch Bridge, the Swing Bridge, the Double-Span Metal Pratt Truss Bridge, Rembrandt Hall and the Tomlinson House are all listed on the National Register of Historic Places, along with the Keeseville Historic District.

Keeseville sits inside Adirondack Park, south of Plattsburgh and just west of Lake Champlain, and the two-mile-long gorge of Ausable Chasm opens in the river just north of the hamlet.

The short Keeseville, Ausable Chasm & Lake Champlain Railroad — nicknamed the 'Peanut Railroad' — connected Keeseville with Port Kent steamships and the Delaware & Hudson Railroad from 1890 to 1924.
