Long Hill Township was incorporated as Passaic Township in 1866. In November, 1992 the voters elected to change the name of the municipality to Long Hill. Long Hill was named one of 25 Great Towns by New Jersey Magazine in March, 1999.

The Township consists of four communities: the villages of Gillette, Millington and Stirling, and the hamlet of Meyersville. Homestead Park is the name of the first subdivision in the Township developed in the 1920's.

Long Hill Township is located in the most southern part of Morris County, New Jersey. It is bounded by the Passaic River on the south and west, and by the Great Swamp National Wildlife Refuge on the north. It borders both Union and Somerset Counties.

In colonial times, Long Hill Township was part of the "Lord Stirling Grant" that included much of the area from Summit to Bernardsville, between Morristown and Watchung.

Long Hill Township has a Township Committee form of government. Five members of the Township Committee are elected for staggered three-year terms. The Committee elects a Chairperson to serve as Mayor for one year.

12.13 square miles. 55% of the Township consists of vacant land, parks, conservation and open space areas, due principally to the existence of wetlands, flood plains and steep slopes. 47% of the township is public parkland.

The highest elevation in Long Hill Township is 449 feet above sea level (northeast of the intersection of Long Hill Rd. and Gillette Rd.).

Long Hill Township is bordered for 12.4 miles by the Passaic River. This is approximately 15% of the entire length of the river.

The longest straight line you could walk within the township is 6.3 miles. Wear boots, since both ends of this walk are in wetlands.
Food for thought. 6.3 miles is also the straight-line distance between Shea and Yankee Stadiums.

Long Hill Township is in the Newark Basin of the Piedmont Physiologic Province. Shales, that were deposited during the Triassic Period, underlie the town. Volcanic activity occurred in the Newark Basin during the early Jurassic Period (181 million years ago). As a result, fissures formed in the earth's surface and flows of basalt occurred on the surface. Later faulting caused the flows to tilt. which resulted in the formation of the Watchung Mountains. A gentle uplifling of the earth in the region caused the streams to erode some of the rock layers.

The "softer" rocks, those more susceptible to erosion, such as the Brunswick shale were gradually eroded, leaving the more resistant Watchung Mountains (Jurassic basalt) standing in relief. In Long Hill Township the hard basaltic rocks of the Third Watchung ridge, known as Long Hill, define the topography and drainage patterns that currently exist. Water falling on the north slope of the ridge drains into the Great Swamp, and on the southern slope moves towards the Passaic River.

The most recent unit of geologic time, the Quaternary Period (the last 2.5 million years), included four glacial stages. The most recent glacial stage, the Wisconsin Glacier reached its maximum extent in New Jersey about 18,000 years ago and began to recede 11,000 years ago. Because of the great thickness (about 2,000 feet in New Jersey) and extent of the glaciers, much of the soil and large amounts of rock were dragged by or incorporated into the ice.

When the climate began to warm, various portions of the glaciers began to melt. The large quantity of sediments and rocks that the glaciers carried were then deposited. The end of the glaciers southern movement in New Jersey is marked by the deposition of the terminal moraine. The terminal moraine in Long Hill Township was deposited atop and alongside the Third Watchung Ridge. This is important because of the superior capacity of the sand and gravel materials in the terminal moraine to permit rain or snow waters to infiltrate down to the underlying aquifers. As a result of the Wisconsin glaciation, a lake known as "Glacial Lake Passaic" was formed in the Newark Basin between the Second Watchung Mountain and the Highlands. Several remnant lakes occupied the lowland areas after the disappearance of Glacial Lake Passaic. Swamps and marshes now occupy those remnant lake basins. These include the Great Swamp, and the wetlands at the confluence of the Dead River and the Passaic River. The sediments left on the slopes of Long Hill after Glacial Lake Passaic receded, now store ground water and release it slowly to the wetlands and the Passaic River. These shallow, unconfined aquifers supply water to a significant number of private wells in Long Hill.
