How to Use This Mountain Lake, New Jersey Map

This interactive map shows the street layout and satellite imagery for Mountain Lake, 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 Mountain Lake.

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 Mountain Lake, New Jersey

Mountain Lake is a locality in Warren County, New Jersey, United States. It is a small community with a population of 494. The population density is 169.4 people per km². Mountain Lake is located at 40.8614°N, 74.9858°W. It observes the Eastern Time (America/New_York) timezone. ZIP code: 07823.

Mountain Lake defines the quiet basin where the cool, still waters of the lake reflect the shifting canopy of the surrounding woodland. It lies 3.7 miles west-southwest of Warren, NJ (from Warren, NJ: bearing 245°T), and is situated 8.2 miles west of Hackettstown. The landscape here is defined by the steady, persistent presence of Jenny Jump State Forest, which encompasses the terrain and lends a sense of ancient, undisturbed stillness to the ground. Near the edges of this dense timber, the Jenny Jump Brook carves a path through the earth, its rhythmic flow providing a constant, low-frequency pulse to the local geography. On clear days, the distant silhouette of the Kittatinny Mountains marks the horizon, a serrated blue line that reminds travelers of the broader, rugged geology of the region. The air here holds a crisp, earthen weight, smelling of damp moss and decaying leaves, particularly as the light softens into the long, golden shadows of the late afternoon.

Mountain Lake exists as an enclave of quiet transition, situated within the protective embrace of Jenny Jump State Forest, where the land has long favored slow, deliberate growth over the frantic pace of the wider world. The local economy and character are deeply tied to the preservation of these woods, with the nearby Pequest Valley serving as a reminder of the agricultural heritage that once dictated the rhythm of life in this part of the state. While the bustle of modern life persists elsewhere, the residents of Mountain Lake maintain a life governed by the changing seasons and the simple, functional beauty of the forest. The proximity to the rushing, hidden power of Foul Rift Falls further serves to ground the area in a landscape that remains wilder and more indifferent to human ambition than the suburban sprawl found further to the east. Here, the day ends not with a grand spectacle, but with the subtle dimming of the sun behind the trees, leaving the surface of the lake to mirror the first, faint stars of the evening.
