Explore Index, Washington, 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 Index, Washington. 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 Washington 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 Index.
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.

Index emerges from the deep, verdant shadows of the valley floor, where the North Fork Skykomish River carves a restless path through the earth. It lies 19.4 miles east of Monroe, WA (from Monroe, WA: bearing 97°T), and is situated 7.0 miles east-southeast of Gold Bar. The air here holds a heavy, persistent moisture, cooling the skin as it drifts down from the distant, jagged silhouette of the Cascade Range. Near the rushing water, the landscape rises in sudden, sheer walls of granite, their surfaces scarred by the slow movement of time and the seasonal weight of persistent rains. A few miles distant, the waters of Lake Serene remain trapped in a high, silent basin, while the nearby spray from Sunset Falls creates a perpetual, shimmering mist that hangs over the forest canopy. The terrain is defined by such verticality, with the open ground of Deer Creek Flat offering a rare, level reprieve before the land pushes upward once more toward the crags and the distant, frozen memory of Columbia Glacier.
Index maintains a quiet, deliberate pace that reflects the rugged constraints of its environment, having long ago transitioned from its origins in the early days of mineral extraction and timber harvest. The local economy now turns toward the preservation of the Forks of the Sky, where the land serves as a gateway for those who seek the solitude of the wilderness rather than the industry of the past. Life in Index is marked by the cycle of the seasons, where the damp gray light of the region dictates the rhythm of the day and the character of the hearth. Even as the modern world encroaches, the influence of the Skykomish Ranger District ensures that the surrounding wild spaces remain largely untouched, anchoring the inhabitants to a landscape that demands respect for its scale. The architecture of the locality—simple, functional, and enduring—speaks to a community that has learned to thrive in the shadow of giants, finding purpose in the quietude of a valley that rarely demands attention but always commands it.

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.
