Explore Lemmon, 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 Lemmon, 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 Lemmon.
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.

Lemmon stretches across the high, expansive plains where the horizon pulls the sky tight against the earth, creating a vastness that humbles the eye. It lies 71.4 miles south-southeast of Dickinson, ND (from Dickinson, ND: bearing 155°T), and is situated 88.8 miles southwest of Bismarck. The landscape is defined by the persistent, dry resilience of the prairie, where the grasses bow to a wind that carries the scent of baked dust and distant growth. Only a mile away, Thunder Hawk Creek carves a thin, erratic line through the topography, its banks marking a quiet passage for the local wildlife. To the west, the faint, jagged silhouette of Rocky Ridge rises against the sunset, a serrated edge of earth that serves as a permanent, silent guardian to the western view. Five miles out, the waters of North Lemmon Lake provide a singular, reflective calm, offering a reprieve from the relentless sweep of the open range.
Agriculture remains the steady pulse of Lemmon, as the rhythm of the seasons dictates the slow, deliberate work of those who tend the soil and manage the livestock. The local economy finds its strength in this deep connection to the land, supported by the proximity of the Grand River National Grassland, which preserves the rugged, untamed character of the region. History lingers in the architecture of the streets, reflecting the hard-won persistence of a settlement built on the grit of the frontier. Life here moves with a measured pace, governed by the quality of light that turns the dry grasses into shimmering gold at dusk and the quiet solitude that settles over the plains once the day’s labor is done.

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.
