How to Use This South Alamo, Texas Map

This interactive map shows the street layout and satellite imagery for South Alamo, 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 South Alamo.

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 South Alamo, Texas

South Alamo is a locality in Hidalgo County, Texas, United States. It has a population of approximately 3,414. The population density is 647.1 people per km². South Alamo is located at 26.1570°N, 98.1086°W. It observes the Central Time (America/Chicago) timezone. ZIP code: 78516.

South Alamo stretches across a flat, sun-drenched expanse where the horizon seems to pull the sky down toward the earth, creating a vast canvas for the shifting light of day. It lies 2.0 miles south-southeast of Alamo, TX (from Alamo, TX: bearing 154°T), and is situated 8.2 miles east-southeast of McAllen. The terrain here is defined by the Main Floodway, a persistent reminder of the land’s hydraulic nature, which cuts through the soil two miles out and dictates the slow, deliberate drainage of the plains. Twelve miles away, the modest rise of Sunrise Hill breaks the monotony of the ground, offering a singular point of elevation in an otherwise level geography. Close to the heart of the grid, Alamo Park provides a quiet green acre where the dust of the fields settles under the shade of native trees, offering a reprieve from the heat that radiates off the pavement during the long, dry afternoons.

South Alamo carries the weight of a frontier history, where the economy has long been tethered to the rhythmic demands of agriculture and the seasonal cycles of the surrounding fields. The legacy of the region is written in the irrigation patterns and the sturdy, unadorned architecture that defines the local character, reflecting a heritage of hard work and deep roots in the soil. Residents often travel seven miles toward the Santa Ana National Wildlife Refuge Trail to find a quieter connection to the natural world, or look toward the distant presence of Hackney Lake Inlet, six miles away, as a marker of the water that sustains the valley. Even further, the Mercedes Settling Basin sits fourteen miles off, a silent witness to the management of local resources that keeps this region viable. Life in South Alamo moves with the steady, predictable pace of a pendulum, grounded in a culture that values the tangible output of the land and the quiet endurance of its people.
