Explore Clayton, Missouri, 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 Clayton, 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 Clayton.
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.

Clayton anchors the landscape with a distinct urban density that rises firmly from the surrounding Missouri plains. It lies 1.2 miles southwest of University City, MO (from University City, MO: bearing 220°T), and is situated 6.9 miles west of St. Louis. Claytonia Creek meanders quietly just a mile away, its presence felt in the subtle moisture that often clings to the morning air. Beyond the immediate development, the horizon offers a faint, distant silhouette of Les Mamelles, providing a grounding perspective to the local skyline. Park #1 serves as a vital green lung for the area, offering a quiet contrast to the structured geometry of the streets. The light here at dusk catches the glass of office towers, casting long, amber shadows over the manicured lawns that define the local topography.
Clayton emerged from a deliberate vision of expansion, evolving from its early roots into a significant administrative and financial hub. The local economy thrives on a robust mix of professional services, legal firms, and corporate headquarters that drive the daily rhythm of the streets. While the modern industry focuses on commerce, the historical weight of the region remains tied to the steady growth of the greater metropolitan area. Local commerce benefits from a sophisticated infrastructure, supporting a stable environment where business interests intersect with civic life. This economic engine ensures that Clayton maintains a focused, professional vitality that permeates the atmosphere throughout the work week.
Clayton fosters a cultural character defined by an appreciation for refined public spaces and a dedication to the arts. Notable landmarks like the public galleries and open-air installations invite residents to pause amidst the brisk pace of their professional duties. Seasonal festivals frequently animate the public squares, drawing people together to celebrate the creative output of the region. Among those who have walked these streets, the actor Jon Hamm stands out as a recognizable figure associated with the local heritage. Life here balances a high-minded intellectual ambition with the plain-spoken sensibility typical of the region, creating a distinctive environment that feels both elevated and accessible.

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.
