How to Use This Greendale, Missouri Map

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

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.

Greendale emerges from the dense, Missouri woodland where the cool, persistent pull of Engelholm Creek shapes the local topography. It lies 2.7 miles east of Overland, MO (from Overland, MO: bearing 99°T), and is situated 7.8 miles northwest of St. Louis. This waterway serves as the primary artery for the landscape, carving a path through the low-slung, verdant ridges that define the immediate perimeter. On clear, crisp days, the distant silhouette of Les Mamelles anchors the western horizon, providing a permanent, shadowed reference point for the low-lying plains. The air here holds a distinct, earthy weight, particularly in the autumn when the light turns amber and lingers over the damp, fertile soil of the creek banks. St Vincent County Park offers a sprawling, silent expanse of preserved timber and brush, ensuring that the wild, unkempt character of the region remains untouched by the encroaching pace of the modern era.

Greendale maintains a quiet, industrious rhythm tied to the legacy of the settlers who first cleared these thickets to establish a foothold in the basin. The local economy relies on the steady, methodical output of small-scale agriculture and the trade routes that have long funneled through this interior corridor. Residents often look toward the nearby waters of Lake Sherwood when the summer heat settles over the fields, finding a sense of scale in its quiet, reflective surface. History in Greendale is not found in grand monuments, but in the stubborn endurance of wood-frame structures and the persistent, plain-spoken manner of those who work the land. While the roar of the Chain of Rocks remains miles away, the distant, rhythmic hum of the landscape provides a constant backdrop to the daily business of life, grounding the people in a geography that demands both patience and respect.

About This Greendale Map Page

This page provides an embedded street and satellite map of Greendale, Missouri. Coordinates: 38.695329, -90.31317. 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 Greendale includes the ZIP code (63121), telephone area code (314), county seat of St. Louis County (Clayton), and school district assignment (Normandy Schools Collaborative).

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.
