Moraine Strait
Moraine Strait () is a strait on the McMurdo Ice Shelf of Antarctica that trends north–south between Brown Peninsula, Mount Discovery, and Minna Bluff on the west, and Black Island on the east. The surface of the strait, especially the northern part between Brown Peninsula and Black Island, is noteworthy for the presence of broad moraine belts that obscure much of the ice and suggest the name. The strait was discovered by the British National Antarctic Expedition, 1901–04, led by Robert Falcon Scott, and
outwash sand. Running along the center of the island like a spine is the moraine left by the glaciers. (Bald Hill, Farmingville, is the highest point along the moraine.) The glaciers also formed Lake Ronkonkoma, a kettle lake.
The island's tallest natural point is Jayne's Hill near Melville, with an elevation of 400.9 feet (122.2 m) above sea level. Long Island is separated from the mainland by the East River, not in fact a river, but a tidal strait. Long Island
