Great Notch takes its name from a literal feature of the landscape — a distinctive gap in the First Watchung Mountain, a basalt ridge formed by ancient Jurassic-era volcanic activity that still defines the area's rolling, elevated terrain. This unincorporated community sits within Little Falls Township in Passaic County, occupying just over one square mile along the eastern edge of the township where it meets the border of Montclair in Essex County.
What sets Great Notch apart from surrounding communities is a combination of geological character, historical depth, and remarkable economic stability. With a median household income of $151,705 and a poverty rate of just 1.4%, the community consistently outperforms neighboring suburbs on nearly every financial measure. The Great Notch Reservoir, constructed in 1900 with a capacity of 179 million gallons, remains a defining local landmark, while the eastern fringe of the community intersects the Montclair State University campus, bringing an academic presence to the immediate area. Rail history runs deep here too — the former Great Notch station served the Erie Railroad's New York and Greenwood Lake Railway as far back as 1873.
For those exploring great notch nj homes for sale, this is a community where mature infrastructure, strong incomes, and a richly layered past converge — making it a compelling choice for buyers who want suburban stability without sacrificing proximity to the broader New York metropolitan area.
