Moraine in Long Island, New York, U.S.
A map showing Long Island's topography and the generalized locations of the glacial moraines.

The Ronkonkoma Moraine, in the geography of Long Island, forms the southern of two ridges along Long Island's "backbone."

Description

The Ronkonkoma Moraine, a terminal moraine, predates the Harbor Hill Moraine (which reached Long Island during the Wisconsin Glacial Episode); the Harbor Hill Moraine cut through the Ronkonkoma Moraine's western portions.

The Ronkonkoma Moraine and the Harbor Hill Moraine intersect at Lake Success in western Nassau County. Today, the moraine is most prominent in Suffolk County, where it traverses the center of Long Island and forms the South Fork.
