Explore Blawenburg, New Jersey, with this interactive street and satellite map.
This page also offers TOPO MAPS — the official USGS topographic sheets — plus USGS aerial imagery, a labelled USNG grid overlay, a distance and bearing tool, and a GPS grid-reference readout. See How to Use This Map below.
This interactive map shows the street layout and satellite imagery for Blawenburg, 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 Blawenburg.
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.

Blawenburg anchors itself firmly within the quiet, inland landscape of central New Jersey, defined largely by the steady, modest passage of Rock Brook as it meanders through the terrain. It lies 3.4 miles east-northeast of Hopewell Mercer County, NJ (from Hopewell Mercer County, NJ: bearing 68°T), and is situated 7.4 miles north-northeast of Mercer. The land here rises in gentle swells toward Pheasant Hill, creating a horizon that feels grounded and permanent rather than dramatic. Near the southern edge of the village, the Montgomery Township Forest offers a quiet expanse of protected greenery where the light filters through the canopy in long, amber slats during the late afternoon. This is a place where the air holds a stillness characteristic of the rural interior, far removed from the bustle of the coast, and where the architecture seems to mirror the low, rhythmic lines of the surrounding fields.
Blawenburg persists as a crossroads of legacy, tracing its origins to a time when the village served as a vital agricultural hub for the surrounding fertile plains. While the local economy has transitioned away from the heavy reliance on early farming, the historic character remains preserved in the sturdy, well-worn structures that define the main thoroughfare. The pace of life here is dictated by the slow, deliberate movement of the seasons rather than the rapid shifts of modern commerce, maintaining a continuity that links the present to the generations who once worked these soil-rich acres. Even as the state around it grows more complex, the village retains a quiet, steady poise, anchored by its history and the enduring presence of the landscape that first invited settlement here.

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.
