Cesspool Installation Wyandanch

This hamlet is named after Chief Wyandanch, a leader of the Montaukett Native American tribe during the 17th century. Formerly known as Half Way Hollow Hills, West Deer Park (1875), and Wyandance (1893), the area of scrub oak and pine barrens south of the southern slope of Half Hollow terminal moraine was named Wyandanch in 1903 by the Long Island Rail Road (LIRR) to honor Chief Wyandanch and end confusion between travelers getting off at the West Deer Park and Deer Park railroad stations. The history of the hamlet has been shaped by waves of immigrants.

No archaeological evidence of permanent Native American settlements in Wyandanch has been discovered. Native Americans hunted and gathered fruits and berries in what is now Wyandanch/Wheatley Heights.

The Massapequa Indians deeded the northwest section of what now is the town of Babylon to Huntington in the Baiting Place Purchase of 1698. The northeast section of the town of Babylon “pine brush and plain” was deeded to Huntington by the Secatogue Indians in the Squaw Pit Purchase of 1699. What is now Wyandanch is located in the Squaw Pit Purchase area. Lorena Frevert reported in 1949 that in the Baiting Place Purchase the Massapequa Indians “reserved the right of fishing and ‘gathering plume and hucel bearyes’.”
