Explore Mount Arlington, 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 Mount Arlington, 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 Mount Arlington.
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.

Mount Arlington occupies a rugged elevation overlooking the expansive, shimmering surface of Lake Hopatcong. It lies 1.4 miles east-southeast of Hopatcong, NJ (from Hopatcong, NJ: bearing 111°T), and is situated 7.3 miles northeast of Mount Olive. The terrain rises sharply from the water, creating a steep, dramatic topography that defines the local skyline. Beyond the immediate shoreline, the landscape settles into dense, wooded ridges that offer a stark contrast to the distant, hazy silhouette of the Kittatinny Mountains on the western horizon. Residents often find that the air here holds a crisp, cool quality even in the height of summer, likely influenced by the deep, cool depths of the lake and the sheltered nature of the surrounding hills. To the south, the terrain levels out somewhat as it approaches the distant reach of the Succasunna Plains, grounding the elevation of Mount Arlington in a broader, flatter geological context.
Early settlers were drawn to the area by its natural resources, which eventually paved the way for a transition from rural industry to a diverse modern economy. While the local economy was once defined by seasonal transit and ice harvesting on Lake Hopatcong, it now relies on a blend of professional services and suburban commerce. The presence of Stephens Brook, located just a mile away, serves as a quiet reminder of the area’s underlying hydrology, which has consistently shaped development patterns over the decades. Mount Arlington maintains a steady, industrious pace, balancing the demands of modern regional business with a respect for the land that first supported its inhabitants. Much of the daily life remains focused on maintaining this balance, ensuring that the legacy of earlier land use does not fade entirely amidst contemporary growth.
The character of Mount Arlington is best observed at the Mount Arlington Recreation area, where the community gathers to enjoy the natural landscape without the intrusion of heavy industry. Local culture is defined by a quiet appreciation for the outdoors, with many residents spending their evenings watching the light fade over the water. While the region is not typically associated with globally famous figures, the quiet dignity of the residents reflects a long-standing tradition of self-reliance and regional pride. Notable landmarks are largely defined by the natural environment, as the proximity to Jenny Jump State Forest offers a vast, untamed space for those seeking solitude away from the suburban density common elsewhere in the state. Traditions here are simple and enduring, often centered around seasonal events that celebrate the specific, changing colors of the trees as autumn descends upon the northern hills.

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.
