The Ronkonkoma Moraine, in the geography of Long Island, forms the southern of two ridges along Long Island's "backbone."[1]
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.[2] The Ronkonkoma Moraine and the Harbor Hill Moraine intersect at Lake Success in western Nassau County.[2] Today, the moraine is most prominent in Suffolk County, where it traverses the center of Long Island and forms the South Fork.[3]
Notable summits
- Bald Hill – 331 ft (101 m)[4]
