Explore Old Jamestown, 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 Old Jamestown, 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 Old Jamestown.
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.

Old Jamestown occupies a quiet stretch of land defined by its inland geography and the subtle, rhythmic shifts of the Missouri terrain. It lies 4.0 miles north-northeast of Florissant, MO (from Florissant, MO: bearing 30°T), and is situated 6.5 miles west-southwest of Alton. Mill Creek weaves through the local landscape just one mile away, offering a steady, low-voiced companion to the surrounding fields. The topography here is marked by the presence of Possum Hollow, a nearby basin that captures the soft, lingering light of late afternoon. To the north, the horizon occasionally holds the faint, distant silhouette of Les Mamelles, grounding the view in a sense of ancient, geological permanence. Residents often watch the shadows lengthen across the open plains, where the air feels clear and stripped of excess.
Old Jamestown traces its origins to the early settlement patterns of the region, where agrarian roots and industrious spirits first took hold. The local economy has long relied on the steady output of its fertile land, drawing upon the traditions of those who recognized the value of this rich soil. Through the decades, the area has maintained a pragmatic focus, blending modest industrial efforts with the needs of a growing, industrious population. Many families here have lived through cycles of change, adapting their work to the evolving demands of the state. This persistent, plain-spoken approach to labor remains a defining feature of the local character.
Life in Old Jamestown finds its rhythm in the quietude of the surrounding woods and the open access to natural spaces like Sioux Passage Park, located just one mile away. On clear days, the atmosphere invites a slow pace, whether one is walking through the nearby greenery or visiting the more distant Chain of Rocks. While the pace of the day-to-day is rarely hurried, the collective identity of Old Jamestown is shaped by a deep appreciation for the landscape’s understated beauty. The community values its proximity to the natural world, favoring the stillness of the trees over the noise of more crowded centers. For those who live here, the simple act of observing the seasons change across the fields provides a profound, quiet satisfaction.

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.
