How to Use This Gray Summit, Missouri Map

This interactive map shows the street layout and satellite imagery for Gray Summit, Missouri. 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 Missouri 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 Gray Summit.

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 Gray Summit, Missouri

Gray Summit is a locality in Franklin County, Missouri, United States. It has a population of approximately 3,055. The population density is 152.8 people per km². Gray Summit is located at 38.4898°N, 90.8168°W. It observes the Central Time (America/Chicago) timezone. ZIP code: 63039.

Gray Summit occupies a high, limestone-ridged plateau where the thick, deciduous woodlands of the Missouri interior begin to thin into the broader reach of the plains. It lies 10.3 miles west of Eureka, MO (from Eureka, MO: bearing 265°T), and is situated 4.1 miles west of Pacific. The air here holds a distinct, heavy clarity, especially as the late afternoon light catches the limestone outcroppings that define the local topography. To the west, the horizon catches the faint, jagged silhouette of the Crescent Hills, while the immediate landscape is drained by the quiet, meandering path of Little Fox Creek. Nearby, the Mobot Shaw Nature Preserve sustains a dense, verdant sanctuary that reflects the region’s original, uncultivated character, offering a stark contrast to the nearby, man-made stillness of Las Brisas Lake.

Gray Summit emerged as a vital transit point, its development tethered to the iron rails and early roads that funneled commerce across the state’s midsection. The local economy maintains a steady, industrious pulse, shifting away from its agricultural origins toward the specialized botanical research and horticultural legacies that define the character of the immediate landscape. Life in Gray Summit moves with a deliberate, measured pace, influenced by a long-standing appreciation for the natural world that sits just beyond the threshold of its paved thoroughfares. Residents often find their quietude in the deeper, shadowed folds of the land, particularly toward the rugged terrain of Coon Hollow, where the history of the region is written into the very soil and the persistent, quiet growth of the surrounding timber.

About This Gray Summit Map Page

This page provides an embedded street and satellite map of Gray Summit, Missouri. Coordinates: 38.489775, -90.816801. Live weather conditions are sourced directly from the National Weather Service. Real-time local and world news feeds keep the page current.

Detailed location data for Gray Summit includes the ZIP code (63039), telephone area code (314), county seat of Franklin County (Union), and school district assignment (Meramec Valley R-III 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.
