Explore Mackay, 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 Mackay, 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 Mackay.
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.

Mackay claims a stark, high-altitude horizon where the air stays thin and sharp enough to cut against the skin. It lies 80.9 miles northwest of Blackfoot, ID (from Blackfoot, ID: bearing 309°T), and is situated 44.4 miles northeast of Hailey. The Swauger Slough carves a quiet, winding path through the sagebrush flats near the base of the valley, its cool presence a rare reprieve from the dry, sun-bleached earth. To the west, the jagged silhouettes of the Lost River Range loom over the landscape, their stony faces holding the deep, fractured shadows of Borah Glacier high in the crags. The light here shifts with a sudden, heavy intensity, casting long, bruised purples across the ground as the sun retreats behind the peaks, leaving the vast, open plains to hold the chill of the coming night.
Mackay emerged from the grit of mining prospectors who scoured the earth for silver and lead, leaving behind a legacy of rusted headframes and stubborn persistence. Today, the economy relies on the quiet rhythm of ranching and the seasonal pulse of travelers drawn to the rugged wildness of Challis National Forest. Life in Mackay moves at the pace of the cattle drives and the slow, steady draw of the irrigation systems pulling from Mackay Reservoir. The Rio Grande Canyon cuts a deep, dramatic wound into the earth nearby, reminding those who live here that the land is not merely a backdrop, but a powerful, ancient force that demands a steady hand and a long memory.

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.
