Explore Mount Vernon, 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 Mount Vernon, 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 Mount Vernon.
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.

Mount Vernon occupies a stretch of fertile Illinois landscape where the horizon pulls wide across fields of corn and soybeans. It lies 19.0 miles southeast of Centralia, IL (from Centralia, IL: bearing 139°T), and is situated 17.5 miles north-northeast of Sesser. Water defines the local geography in quiet, unassuming ways, with Casey Fork flowing just a mile away to drain the surrounding plains. The Louisville and Nashville Reservoir sits at a similar distance, offering a reflective surface that catches the heavy, golden light of late summer afternoons. Looking toward the horizon, the silhouette of Fleming Ridge remains visible twenty-one miles away, grounding the flat expanse with a distant, hazy permanence. Residents often find recreation within the bounds of Optimist Park, a space that serves as a central point for outdoor gatherings.
Mount Vernon traces its origins to the practical needs of settlers who recognized the potential in this agricultural crossroads. The local economy grew by leveraging its position as a transit point, eventually drawing strength from coal mining and the steady rhythms of regional manufacturing. These industries shaped the town’s character, fostering a resilient workforce that understands the value of labor and the necessity of adaptation. Over the decades, the landscape has been altered by the extraction of resources and the expansion of rail and road, yet the influence of the soil remains constant. Even as modern commerce shifts, the economic pulse of Mount Vernon continues to reflect the industrious spirit of the Midwestern plains.
Cultural life in Mount Vernon is punctuated by community traditions and a sense of shared purpose that persists through the changing seasons. The town serves as a quiet center for local art and history, often drawing people to gatherings that celebrate the regional identity. Landmarks throughout the area provide anchor points for daily life, standing as quiet witnesses to the passage of time. Among those who have emerged from the region, the actor Al Joyner stands out for his achievements on the national stage, bringing a measure of recognition to his home. Whether through the bustle of a local event or the stillness of an evening, Mount Vernon maintains a distinct, deliberate pace that favors steady connection over the frantic speed of larger urban centers.

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.
