Explore Mason, Illinois, 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 Mason, Illinois. 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 Illinois 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 Mason.
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.

Mason occupies a vast, level expanse of the Illinois interior, where the horizon stretches flat and wide under an immense, unyielding sky. It lies 14.2 miles south of Carbondale, IL (from Carbondale, IL: bearing 188°T), and is situated 4.4 miles north of Anna. The landscape surrounding Mason remains dominated by the quiet persistence of agricultural cycles, defined by the seasonal shift from dark, turned earth to the high, verdant stalks of corn and soybeans that absorb the summer heat. To the west, the cooling influence of Clear Creek cuts through the terrain, while the dense, shadowed canopy of the Trail of Tears State Forest provides a wilder contrast to the orderly grid of the fields. In the distance, the rugged, elevated silhouette of Atwood Ridge breaks the monotony of the plains, acting as a permanent, stoic sentinel against the encroaching clouds that drift across the center of the continent.
History in Mason lingers in the weathered grain of wooden barns and the sturdy, pragmatic architecture that prioritizes function over ornament. The local economy persists through a deliberate, steady rhythm of harvest and commerce, tethered to the land and the quiet movement of goods along the regional veins of transport. Residents often find respite in the Shawnee Purchase Unit, a sprawling expanse that invites a slower pace of life, or observe the stillness of the Anna State Hospital Reservoir, where the water reflects the gray, bruised light of late autumn afternoons. Beyond the immediate reach of Kratzinger Hollow, the life of the place is measured not in grand gestures but in the recurring, familiar labor of those who work the soil, ensuring that the character of Mason remains as enduring as the deep, black loam 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.
