The Eramosa Karst is a provincially significant Earth Science Area of Natural and Scientific Interest in Ontario, Canada, located in Stoney Creek, a constituent community of the City of Hamilton, and immediately south of the Niagara Escarpment.It exhibits sixteen different karstic geological features, of which seven are provincially significant, and is considered to be the best example of karst topography found in Ontario. The area is composed of parcels of land that are provincially, municipally and privately owned. It received ANSI-ES designation on February 13, 2003.Conservation areaIn October 2006, Ontario donated 73 ha of land to the Hamilton Conservation Authority to create a new conservation area, followed by another donation of 3.1 ha in April 2007. The City of Hamilton has also contributed in June 2007 by transferring 1.6 ha. The area opened to the public on June 20, 2008.LandformThe area is crossed by the Eramosa Escarpment. It is morphologically similar to the Niagara Escarpment, as both are composed of the Lockport Formation dolostones. However, the Eramosa Escarpment is much smaller in height (no more than 10 metres); its crest is only occasionally defined by cliffs, which are no higher than 3 metres. Most of the bedrock is buried by till.
