How to Use This Carthagena, Ohio Map

This interactive map shows the street layout and satellite imagery for Carthagena, Ohio. 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 Ohio 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 Carthagena.

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.

Carthagena occupies a quiet expanse of flat, fertile farmland where the horizon stretches wide under a sky that feels heavier and more deliberate than elsewhere. It lies 7.8 miles south of Celina, OH (from Celina, OH: bearing 176°T), and is situated 4.7 miles southeast of Coldwater. Beaver Creek carves a shallow, unassuming path through the dark, loamy soil, its waters moving with a slow, meditative intent that mirrors the stillness of the surrounding fields. At the edge of the property lines, the Mercer County Elks Country Club provides a manicured contrast to the wilder, unkempt growth along the creek banks, offering a green refuge where the grass is kept short and the air holds the scent of mown hay. When the late afternoon sun hits the irrigation lines, the light turns a bruised, golden shade, illuminating the dust motes that hang suspended in the humid, inland heat.

Carthagena retains the steady, industrious spirit of its mid-nineteenth-century roots, when the landscape was shaped by those seeking a place to cultivate independence and community. The local economy remains tethered to the rhythmic demands of agriculture and the maintenance of the land, with the nearby presence of Grand Lake serving as a silent, expansive anchor for the region’s hydrology just four miles to the west. Life here moves according to the turning of the seasons, defined by the planting and the harvest rather than the frantic pace of distant urban centers. The legacy of the area is not found in grand monuments, but in the enduring, quiet persistence of the families who work the earth, maintaining a way of life that values the weight of a handshake and the patience required to watch a crop grow to maturity.
