How to Use This Agar, South Dakota Map
This interactive map shows the street layout and satellite imagery for Agar, 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 Agar.
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.

ZIP code: 57520.Agar stretches across a vast, amber-hued expanse of the Great Plains, where the horizon pulls the sky taut against the earth in a relentless, open geometry. It lies 35.2 miles north-northeast of Pierre, SD (from Pierre, SD: bearing 23°T), and is situated 51.3 miles south-southeast of Mobridge. The land around Agar is defined by a rhythmic, undulating prairie that breathes with the changing seasons, marked occasionally by the low, meditative flow of Okobojo Creek as it carves its path through the silt. To the west, the distant profile of Artichoke Butte rises like a silent sentinel above the grasses, while the quiet waters of Mundt Lake reflect the vast, unpolluted clarity of the celestial dome. Here, the air carries a dry, crisp weight that sharpens the edges of every fence line and silo, grounding the observer in a landscape that demands both patience and a quiet reverence for the scale of the plains.
Agar was built upon the industry of the soil, a place where the economy remains tethered to the cycles of planting and harvest that dictate the tempo of local life. While the quietude of the plains suggests a stillness, the history of Agar is marked by the persistent labor of those who turned this sod into a patchwork of productive fields. The proximity to Onida provides a tether to the broader regional conservation efforts, ensuring that the wilder character of the land remains preserved against the encroachment of modern haste. In the evening, when the light turns a deep, bruised copper, the people of Agar move with a steady, deliberate grace, their lives echoing the enduring resilience of a settlement that has long found its purpose in the honest, heavy work of the earth.

About This Agar Map Page
This page provides an embedded street and satellite map of Agar, South Dakota. Coordinates: 44.838315, -100.074567. 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 Agar includes the ZIP code (57520), telephone area code (605), county seat of Sully County (Onida), and school district assignment (Agar-Blunt-Onida School District 58-3).
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.
