How to Use This Ocosta, Washington Map

This interactive map shows the street layout and satellite imagery for Ocosta, 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 Ocosta.

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.

About Ocosta, Washington

Ocosta is a locality in Grays Harbor County, Washington, United States. It is a small community with a population of 502. The population density is 64.5 people per km². Ocosta is located at 46.8887°N, 124.0385°W. It observes the Pacific Time (America/Los_Angeles) timezone. ZIP code: 98520.

Ocosta occupies a low-lying stretch of land where the persistent dampness of the Pacific air defines the very texture of the morning. It lies 12.1 miles west-southwest of Aberdeen, WA (from Aberdeen, WA: bearing 240°T), and is situated 9.5 miles southwest of Hoquiam. Redman Slough snakes through the terrain like a dark, silvered vein, draining the marshy flats toward the broader reaches of Bowerman Basin, which sits only a mile from the salt-heavy edge of the coast. The landscape remains stubbornly flat, a muted expanse of silt and tide-washed grasses that feels far removed from the jagged, distant spine of the Cascade Range. At Bottle Beach, the horizon dissolves into a gray, liquid seam, while the distant, low silhouette of Traitors Islet emerges periodically from the shifting fog, serving as a silent sentinel for the tides that claim the shore.

History lingers in Ocosta not as a grand monument, but as a quiet endurance, rooted in the remnants of a once-ambitious past that sought to carve a port out of the stubborn mud. The local economy has long bowed to the seasonal demands of the water, favoring the harvest of the tide and the careful management of the maritime edge over the clamor of industry. Life here follows the pulse of the changing water levels, an unhurried existence where the wind carries the scent of brine and decaying cedar across the flats. Residents often look toward the interior of the state with a detached perspective, finding their own rhythm in the isolation of the coast and the occasional, mirrored stillness of Cohassett Lake, which holds the sky in its dark, glassy surface three miles away.

About This Ocosta Map Page

This page provides an embedded street and satellite map of Ocosta, Washington. Coordinates: 46.888702, -124.038504. 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 Ocosta includes the ZIP code (98520), telephone area code (425), county seat of Grays Harbor County (Montesano), and school district assignment (Ocosta School District).

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.
