How to Use This East Rocky Hill, New Jersey Map
This interactive map shows the street layout and satellite imagery for East Rocky Hill, New Jersey. Use the Map and Satellite buttons above to switch between street map and aerial imagery views. Use the + and − buttons to zoom in or out, or scroll your mouse wheel while holding the Control key to zoom. On a touchscreen, use a two-finger pinch gesture. Drag the map to pan to any area of New Jersey or beyond.
Click ⛶ Fullscreen to expand the map to fill your screen. To return to the normal page view, press the Escape key, click the ✕ Exit Fullscreen button that appears above the map, or on a mobile device tap the back button (Android) or the close icon (iOS).
TOPO MAPS — NEW. Click the green 🔍 Search Maps button below the map to open a second map with a Base map row offering three choices. OSM is the standard OpenStreetMap street map. Topo shows the official USGS topographic maps from The National Map — contours, hydrography, land cover and shaded relief, the same mapping used for hiking, hunting and back-country navigation in the Adirondacks, the Catskills and the Finger Lakes. Imagery shows USGS aerial photography, mostly 1-metre NAIP. The search box finds any US town, county or landmark by name, so you are not limited to East Rocky Hill.
Reading the map like a paper quad. Click Grid to overlay the U.S. National Grid (USNG), labelled along the edges exactly as a printed topographic sheet is — at normal zoom the squares are one kilometre across, so you can read a six-figure grid reference by eye and judge distance directly off the map. Click Measure, then tap two points, to get the distance between them together with the grid bearing in degrees and mils, the true bearing, and the magnetic bearing to set on a compass.
Click 📍 My position to take a single GPS reading from your device. It marks where you are and reports your position as a USNG grid reference as well as plain latitude and longitude — USNG being the format FEMA and US search and rescue teams work from — with a Copy position button so you can paste it straight into a text message. It takes one reading and stops, rather than tracking continuously, to conserve your battery. Note that map tiles need cell coverage, but a GPS reading does not — your coordinates stay correct even where the map itself cannot load.

About East Rocky Hill, New Jersey
East Rocky Hill is a locality in Somerset County, New Jersey, United States. It is a small community with a population of 468. The population density is 43.4 people per km². East Rocky Hill is located at 40.4079°N, 74.6128°W. It observes the Eastern Time (America/New_York) timezone. ZIP code: 08540.East Rocky Hill rises from the inland terrain as a collection of slopes and quiet clearings that hold the afternoon light in a lingering, amber suspension. It lies 2.9 miles west-southwest of Kendall Park, NJ (from Kendall Park, NJ: bearing 252°T), and is situated 9.7 miles northeast of Mercer. The landscape is defined by the steady, unobserved movement of Carters Brook, which carves a modest path through the earth only a mile away, feeding the moisture that sustains the local greenery. Beyond the immediate canopy, the land stretches toward the distant, hazy silhouette of Middlebrook Heights, while the South Franklin Initiative occupies the surrounding acreage to preserve the integrity of the soil. When the sun dips low, the shadows stretch across the fields with a deliberate weight, transforming the ordinary grass and brush into a textured expanse of deep ochre and slate.
History clings to the bedrock of East Rocky Hill, where the echoes of early settlement remain pressed into the modern layout of residential roads and small-scale enterprise. The regional economy operates with a quiet efficiency, far removed from the frantic pace of larger hubs, favoring a rhythm dictated by the seasonal shifts of the inland climate. Residents often look toward the nearby expanse of Carnegie Lake, a two-mile distance that provides a reflective surface for the changing sky. Life here is characterized by this balance between the preservation of the South Franklin Initiative and the steady, unremarkable persistence of daily labor, creating an environment where the passage of time is measured not in grand events, but in the slow, natural growth of the woods and the quietude of the evening air.

About This East Rocky Hill Map Page
This page provides an embedded street and satellite map of East Rocky Hill, New Jersey. Coordinates: 40.4079, -74.6128. Live weather conditions are sourced directly from the National Weather Service. Real-time local and world news feeds keep the page current.
Detailed location data for East Rocky Hill includes the ZIP code (08540), telephone area code (609, 640), county seat of Somerset County (Somerville), and school district assignment (Franklin Township School District).
Search Maps opens a second, independent map. It searches OpenStreetMap for any US town, county or landmark by name; offers USGS topographic maps and USGS aerial imagery as base layers; overlays a labelled U.S. National Grid (USNG) so the map can be read like a printed topographic quad; measures distance and grid, true and magnetic bearings between any two points; and takes a single GPS fix reporting your position as a USNG grid reference and as latitude and longitude. Map tiles require cell coverage, but a GPS position does not, so the coordinates remain correct even where the map cannot load.
Location data is drawn from the USGS Geographic Names Information System (GNIS) and cross-verified against 2020 US Census records by coordinate proximity. Population figures are sourced from the 2020 US Census.
