Explore Jefferson, Iowa, 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 Jefferson, Iowa. 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 Iowa 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 Jefferson.
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.

Jefferson rises from the vast, dark-soiled prairie where the horizons stretch wide enough to swallow the sun each evening in a slow, amber dissolution. It lies 25.4 miles east of Carroll, IA (from Carroll, IA: bearing 98°T), and is situated 18.5 miles northwest of Perry. The landscape around Jefferson is defined by the rhythmic geometry of tilled fields, where the heavy, mineral-rich earth yields its seasonal harvest of corn and soybeans under an expansive, unshielded sky. To the west, the subtle, undulating terrain hints at the distant presence of the Loess Hills, while the cool, persistent presence of the North Raccoon River carves a quiet path through the nearby woodland. Russell Park provides a green, quiet pause within the grid, offering a stillness that persists even as the wind rustles through the tall grasses, and the distant, hazy silhouette of Frankel Ridge occupies the far edge of the mind’s eye.
Jefferson serves as a sturdy anchor for the surrounding agricultural economy, its streets arranged with a deliberate, mid-century civility that reflects a history built upon German and Scandinavian industry. The town square is dominated by its iconic courthouse tower, a landmark that keeps time for a population deeply attuned to the cycles of the planting and harvest seasons. Life in Jefferson maintains a steady, focused pace, grounded by the practicalities of regional commerce and the quiet, literate traditions of the upper Midwest. As the light fades and the gray shadows lengthen across the flat plains, the atmosphere takes on a meditative quality, where the primary sounds are the distant hum of machinery and the soft, evening settling of the prairie air.

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.
