Explore Ortley, South Dakota, 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 Ortley, South Dakota. 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 South Dakota 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 Ortley.
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.

Ortley occupies a quiet stretch of the high prairie where the horizon seems to pull the sky down toward the earth in a wide, unbroken arc. It lies 30.2 miles north of Watertown, SD (from Watertown, SD: bearing 353°T), and is situated 28.3 miles west-northwest of Milbank. The land here is defined by the persistent, rhythmic shift of grasses under the wind, revealing a landscape that is less about verticality and more about the vast, horizontal reach of the plains. Just a mile away, the surface of Bill Smith Slough catches the pale, early light, reflecting a sky that shifts from bruised violet to a stark, clear blue as the morning matures. Beyond the immediate reach of the township, the land flattens into an expanse where the Big Sioux River carves a subtle, winding path through the soil four miles to the south. The light at dusk here possesses a particular density, turning the wild grasses into a field of burnished copper that holds the heat of the day long after the sun has dipped below the western edge of the world.
History in Ortley remains tethered to the slow, deliberate work of the soil and the iron rails that once tethered such outposts to the wider world. The regional economy leans heavily upon the endurance of agriculture, with the daily life of the residents governed by the seasonal cycles of planting and harvest that have defined this geography for generations. Those seeking the quietude of the natural world often turn toward the Ortley SCA, where the stewardship of the land preserves a glimpse of the prairie as it existed before the arrival of the plow. While the distant silhouette of Punished Womans Mound marks the landscape twenty-two miles away, the character of the place is found in the modest, persistent details of a slow-turning life. There is a profound honesty in the way the wind moves across the plains, an unadorned clarity that strips away the unnecessary until only the essential rhythm of the earth remains.

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.
