Explore Charco, Arizona, 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 Charco, Arizona. 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 Arizona 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 Charco.
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.

Charco defines itself through the relentless clarity of the Sonoran sun, which bleaches the earth into shades of pale ochre and bone. It lies 53.0 miles south-southwest of Estrella, AZ (from Estrella, AZ: bearing 192°T), and is situated 17.1 miles east-southeast of Ajo. The landscape around Charco stretches outward in a vast, arid expanse, where the ground is broken only by the stiff, sentinel silhouettes of saguaro and the tangled, whip-like branches of ocotillo. To the west, the subtle depression of Needle Valley pulls the eye toward a horizon dominated by the distant, hazy profile of Ninemile Peak. Moisture is a rare visitor here, channeled primarily through the bed of the Sikort Chuapo Wash, a dry, gravel-choked ribbon that only finds its voice when the monsoon clouds gather their dark, electric weight. The air carries a dry, mineral sharpness, and as dusk approaches, the light softens into a bruised violet that clings to the scrub, turning the desert floor into a theater of lengthening shadows and profound, ringing stillness.
Human presence in Charco remains a quiet negotiation with an environment that demands resilience, echoing the long, layered history of the region’s original inhabitants and the later, rugged homesteaders who sought a living from the dust. Economic life functions at a measured pace, often tethered to the rhythms of ranching or the maintenance of sparse infrastructure that supports a life lived largely outdoors. Beyond the immediate settlement, the expansive reach of State Trust Land offers a protected buffer of raw, uncultivated terrain where the passage of time is measured by the steady erosion of stone rather than the tick of a clock. Life in Charco persists with a singular, unvarnished integrity, where the primary landmarks are the enduring geometry of the land itself and the wide, uncaring sky that arches over the valley, indifferent to the small, fleeting efforts of those who reside beneath it.

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.
