Once the island splits into two forks at its east end, the North Shore's hills largely flatten out (and enter the Town of Riverhead) to an out-wash plain and becomes largely rural (and enters the Town of Southold), with an economic stronghold on agriculture, particularly in the shape of wineries and vineyards. This recent trend, beginning in the 1980s with the conversion of potato farms, has given the North Fork the distinction of being the most productive agricultural area in New York State. Despite this, North Fork, contrasts starkly with the more populated and more well-known South Fork's Hamptons. The North Fork terminates at Orient Point, where the Cross Sound Ferry Company has a terminal for ferries bound for New London, CT. and Block Island, RI.
