Explore Grand Mound, 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 Grand Mound, 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 Grand Mound.
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.

Grand Mound occupies a distinctive geological rise that lifts its residents slightly above the surrounding alluvial plains, grounding the landscape in a quiet, enduring stability. It lies 5.6 miles north-northwest of Centralia, WA (from Centralia, WA: bearing 331°T), and is situated 9.0 miles north-northwest of Chehalis. The horizon often holds the faint, jagged silhouette of the Cascade Range, a distant wall that reminds those present of the vast, varied terrain stretching toward the eastern interior. To the immediate north, the expansive openness of Grand Mound Prairie provides a flat, grassy counterpoint to the more heavily timbered reaches of the region, while the cooling influence of the nearby Capitol State Forest contributes to a persistent, damp vitality in the air. The gentle current of Prairie Creek meanders through the periphery, carving a subtle path through the earth, while the quiet stillness of Dunlap Pond offers a reflective surface for the changing light of the seasons.
History in Grand Mound lingers in the transition from early agricultural roots to a modern intersection of transit and local enterprise. The economy maintains a steady, utilitarian pace, supported by a mix of service-oriented businesses and the lingering influence of the agrarian traditions that first claimed the soil. Residents often find recreation at the Theodore Hoss Sports Complex, a site that anchors the social energy of the vicinity, while those seeking the more dramatic natural features of the region can travel toward the cascading waters of Mima Falls. Life here is defined by a measured, deliberate tempo, where the gray, low-hanging skies of the Pacific Northwest settle over the fields and roadways, lending a sense of permanence to the daily cycles of work and rest in Grand Mound.

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.
