Explore Marty, 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 Marty, 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 Marty.
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.

Marty emerges from the high, open plains where the wind shapes the tall grasses into shifting waves of gold and amber. It lies 52.7 miles west of Yankton, SD (from Yankton, SD: bearing 280°T), and is situated 28.4 miles west-northwest of Springfield. Mosquito Creek carves a narrow, winding path through the heavy soil, its banks providing a sliver of green relief against the vast, sun-bleached expanse of the surrounding prairie. To the west, the distant profile of Old Baldy rises against the sky, a silent anchor for the horizon, while the terrain dips into the quiet, shadowed depths of Ninemile Gulch. When the light of late afternoon catches the dust, the air takes on a bruised, violet hue, turning the austere landscape into a place of sudden, fleeting grace that feels both ancient and entirely indifferent to the passage of human time.
Marty holds a profound connection to the culture of the Yankton Sioux Tribe, serving as a center of community life where the echoes of the past inform the steady, deliberate pace of the present. The local economy remains tethered to the rhythms of the earth, defined by the seasonal cycles of agriculture and the stewardship of the land that stretches toward the Francis Case Recreation Area. Residents often look toward the waters of Micanek Reservoir, which shimmer in the distance as a reminder of the quiet gravity of the local topography. Life here moves with a gravity of its own, far removed from the frantic hum of urban centers, favoring a social fabric woven from long-standing traditions and the shared, quiet labor of those who call these plains home.

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.
