A prominent feature of Northport is Steer’s Pit (known simply as “The Pit” to locals), a large land depression carved into the cliffs adjacent to Northport Harbor and just south of the enormous LIPA smokestacks. This unusual geographic feature is the result of sand mining operations by the Steers and Steers Company. Mining began in 1923 and ceased in the 1950s. The mined sand was shipped by barge to New York City where, mixed with Portland cement and rock aggregate, it became the sidewalks of New York. The area has since been utilized for home and condo use, and a portion of the Pit is a park used by local youth soccer and baseball leagues. The Northport Fire Department maintains a training facility in the Pit that is the site of the annual firemen fair in the summer.
