The glaciers from the north deposited sediments that now make up the foundation of Long Island. As the global climate warmed, melting ice and flowing waters eroded the dropped glacial sediments into the shape of a land called "Pamanouk" or the island we call Long Island. The island's northern bluffs were interrupted by several rivers and a number of harbors. One of these is now Mount Sinai Harbor.
