How to Use This Lost River, Idaho Map
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.

ZIP codes: 83255, 83251.Lost River emerges from the high, arid expanse where the sagebrush plains meet the stark, sudden verticality of the earth. It lies 72.3 miles west-northwest of Blackfoot, ID (from Blackfoot, ID: bearing 299°T), and is situated 36.9 miles east-northeast of Hailey. Antelope Creek carves a deliberate path through the basin, its waters sustaining a narrow ribbon of green that defies the surrounding parched dust and gray rock. To the horizon, the jagged silhouette of the Lost River Range commands the sky, its peaks holding the light long after the shadows have claimed the valley floor. Only a mile away, the rugged, shadowed depths of Graveyard Canyon offer a silent contrast to the open basin, while the nearby Idaho Department of Lands provides a vast, managed threshold for those who venture into the wilder reaches of the high desert.
Agriculture remains the quiet pulse of Lost River, where the rhythm of the seasons dictates the labor of the day and the lean, hard-working character of the residents. The economy relies upon the endurance of those who know how to draw a living from the stubborn soil, a practice that has defined the region since its earliest settlement. Ten miles away, the waters of Nichols Reservoir stand as a still, reflective presence, serving as a vital anchor for the local landscape. Life here possesses a gravity born of isolation and the immense, open sky, where the wind carries the scent of dry earth and the persistent, quiet promise of a long, cold winter.

About This Lost River Map Page
This page provides an embedded street and satellite map of Lost River, Idaho. Coordinates: 43.688262, -113.635283. 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 Lost River includes the ZIP code (83255, 83251), telephone area code (208), county seat of Custer County (Challis), and school district assignment (Butte County Joint School District 111).
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.
