Explore Lost River, Idaho, 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 Lost River, Idaho. 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 Idaho 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 Lost River.
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.

Lost River carves a path through a high, arid basin where the light possesses a sharp, clinical clarity that strips the shadows from the sagebrush. It lies 62.0 miles northwest of Blackfoot, ID (from Blackfoot, ID: bearing 304°T), and is situated 48.7 miles east-northeast of Hailey. The Big Lost River courses through the valley floor, its currents often pulling away from the surface to vanish into the porous, volcanic earth before rising again to cool the parched soil. To the distance, the jagged silhouettes of the Lost River Range loom against the horizon, marking the outer perimeter of a landscape defined by silence and the slow movement of wind over bunchgrass. Two miles to the east, the rugged terrain of the Appendicitis Hill Wilderness Study Area rises in solitary defiance, its slopes untouched by the plow, while the hidden depressions of Rocky Canyon offer a shadowed reprieve from the relentless sun that bleaches the plains of Lost River into shades of pale ochre and gray.
Agriculture remains the primary pulse of the local economy, with the irrigation of fields drawing life from the water that persists despite the dry climate. Those who work this land measure their time by the seasonal cycles of the harvest and the maintenance of fences that stretch toward the horizon, far from the recreational pull of the Nichols Reservoir. History here is written in the labor of those who cleared the basalt-strewn earth, finding resilience in a geography that demands much and promises little beyond the quiet endurance of the high desert. Life in Lost River moves with a deliberate, measured pace, influenced by the vastness of the sky and the reality of a terrain that refuses to be tamed, leaving the inhabitants to exist in a persistent, dignified harmony with the harsh, beautiful constraints of the region.

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.
