How to Use This San Carlos II, Texas Map
This interactive map shows the street layout and satellite imagery for San Carlos II, Texas. 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 Texas 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 San Carlos II.
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 San Carlos II, Texas

San Carlos II is located at 27.4901°N, 99.3684°W. It observes the Central Time (America/Chicago) timezone. ZIP code: 78043.San Carlos II occupies a stretch of sun-bleached earth where the horizon pulls wide and flat, defined by the low, persistent scrub of the brush country. It lies 8.6 miles east of Laredo, TX (from Laredo, TX: bearing 97°T), and is situated 11.1 miles northeast of Rio Bravo. The air here holds a dry, heat-thickened clarity that sharpens the silhouettes of distant mesquite and makes the far-off rise of El Pico appear as a faint, jagged bruise against the pale sky. Two miles to the east, the bed of Dolores Creek cuts a shallow, winding scar through the clay, its banks often bone-dry until the rare, violent rains turn the dust to slick iron-colored mud. Near the center of the residential grid, Self-Help Center Park offers a modest patch of green where the light of late afternoon catches the dust motes in long, golden shafts, turning the common space into a quiet sanctuary before the cooling dark.
San Carlos II bears the distinct, unhurried imprint of border-country life, where the local economy turns on the slow, rhythmic labor of ranching and the commerce that flows across the nearby international divide. History here is kept not in grand monuments, but in the enduring Spanish-language cadence of the streets and the collective memory of families who have worked this soil for generations. Five miles to the north, the waters of Lake Casa Blanca shimmer under the relentless sun, providing a necessary anchor for the surrounding plains and a place where the heat of the day finally breaks. Life in San Carlos II moves with the steady, predictable pulse of a place that understands its own isolation, finding a quiet, sturdy beauty in the way the wind moves through the dry grass and the way the evening light lingers over the fence lines.

Detailed location data for San Carlos II includes the ZIP code (78043), telephone area code (210, 726), county seat of Webb County (Laredo), and school district assignment (United Independent School District).
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.
