Explore Irwin, 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 Irwin, 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 Irwin.
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.

Irwin maintains a quiet gravity where the high desert air meets the persistent, cold pulse of the Snake River. It lies 33.7 miles east of Ammon, ID (from Ammon, ID: bearing 97°T), and is situated 16.4 miles southwest of Victor. This landscape is defined by the proximity of Flatiron Hollow, a shallow depression that channels the wind across the sagebrush and bunchgrass toward the water’s edge. The terrain here is not a place of sudden drama, but of enduring, arid patience, where the light at dusk turns the earth a bruised, metallic violet before the stars sharpen against the dark. Everything in Irwin exists under the oversight of the Snake River Area of Critical Environmental Concern, a designation that ensures the wild character of the riverbanks remains undisturbed by the slow press of human expansion.
Economic life in Irwin has long been tethered to the rhythms of the land and the seasonal flow of the river, which draws those seeking the solitude of the surrounding wilderness. To the east, the distant, craggy silhouettes of the Snake River Range provide a permanent horizon, while the nearby cascade of Fall Creek Falls serves as a singular, rhythmic punctuation mark in the quietude of the backcountry. While the Palisades Reservoir lies only seven miles away, the daily existence here is governed more by the local stewardship of the Targhee National Forest and the necessity of managing the rugged, unyielding soil. Life in Irwin moves with the unhurried precision of a place where the seasons dictate the labor, leaving the inhabitants to witness the slow, inevitable cycle of the frost and the thaw.

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.
