Jayne Hill (also known as High Hill, West Hills, Oakley Hill, and Janes Hill) is the highest point on New York Long Island, with an elevation of between 387 feet (118 m) and 400.9 feet (122.2 m) above sea level as its mentioned in Long Island elevation map. It is situated on the Harbor Hill Terminal moraine that makes up the northern spine of Long Island in West Hills County Park in Suffolk County, a little more than a mile to the north of Melville.
Bald Hill, located in the hamlet of Farmingville, New York, part of the Town of Brookhaven, is one of the highest areas of elevation on Long Island as you can see in Long Island elevation map. The highest elevation in the Bald Hill area is 331 feet (101 m). Though local residents often claim it to be the highest point on Long Island, that honor actually belongs to Jayne Hill in the Town of Huntington at 401 feet (122 m). Also, nearby Telescope Hill, about 0.8 miles (1.3 km) WSW, is slightly higher at 334 feet (102 m). Bald Hill in Brookhaven should also not be confused with Bald Hill in Riverhead.
The most prominent landforms of Long Island are the two lines of hills that form the "backbone" and the "forks" of the island, the gently sloping plain that extends southward from the hills, the deeply eroded headlands along the north shore, and the barrier beaches along the south shore. The two lines of hills, known as "terminal moraines" reach a maximum altitude of about 400 feet above sea level, and are separate and distinct in the central and eastern parts of the island, but merge in the western part as its shown in Long Island elevation map. The southernmost lines of hills the Ronkonkoma moraine is the older of the two; it extends eastward to form the South Fork. The northern line of hills, the Harbor Hill moraine extends eastward along the north shore of Long Island to form the North Fork. The outwash plain generally begins at an altitude of about 100-150 feet, and slopes southward at a rate of about 20 feet per mile until it merges with recent swampy deposits along the coast (Cohen and others, 1968).
