Snake Hill
Snake Hill, officially known as Laurel Hill, is a diabase igneous intrusion rising approximately 150 feet from the surrounding Hackensack Meadowlands in southern Secaucus, Hudson County, New Jersey.[1][2]
Formed by a subsurface magma intrusion during the Early Jurassic period around 200 million years ago as part of the Central Atlantic Magmatic Province associated with the breakup of Pangaea, it represents a classic example of a resistant diabase sheet intruded into the sedimentary rocks of the Newark Basin.[2]
Originally towering over 200 feet high with a base spanning about 25 acres, the formation was extensively quarried starting in the 19th century for trap rock used in regional construction, reducing its size dramatically by the mid-20th century.[1][3]
Hudson County purchased the site in 1855 and developed it into a self-contained complex that included a poor farm, almshouse, tuberculosis hospital, county jail, and insane asylum, with an adjacent potter's field serving as the burial ground for thousands of indigent, immigrant, and institutionalized individuals, many in unmarked graves.[1][3][4]
The site's dark historical legacy came to light in the early 2000s during New Jersey Turnpike expansion, which led to the exhumation and relocation of documented remains but left an estimated 4,000 to 5,000 burials undisturbed due to incomplete records.[4][3]
The remnants of Snake Hill now form a key feature of Laurel Hill County Park, attracting visitors interested in its geological prominence, ecological surroundings, and sobering human history.[1][2]
