Explore Prosser, 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 Prosser, 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 Prosser.
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.

Prosser occupies a wide, sun-drenched expanse where the Yakima River carves a deliberate path through the arid landscape. It lies 7.0 miles east-southeast of Grandview, WA (from Grandview, WA: bearing 116°T), and is situated 14.8 miles west-southwest of Benton. This inland corridor finds its character in the stark contrast between the dry, sage-dotted plains and the verdant irrigation that sustains life here. To the west, the distant silhouette of the Cascade Range looms against the horizon, anchoring the sky with a jagged, immutable presence. Prosser maintains a quiet gravity, as the quality of light at dusk softens the sharp edges of the land into muted shades of gold and violet. Nearby, the terrain folds into the quiet reach of Crow Canyon, while the waters of Byron Ponds offer a still, reflective reprieve from the heat.
Prosser traces its origins to the arrival of the railroad, which transformed the dusty basin into a hub for agricultural expansion and trade. The local economy thrives on the industrious spirit of the region, where rows of vineyards and orchards stretch toward the horizon in precise, geometric lines. This industry serves as the lifeblood of the area, drawing upon the fertile soil and long growing seasons that define the valley floor. Prosser supports a robust commitment to viticulture, establishing itself as a significant contributor to the regional production of wine. Modern enterprises here balance these deep-rooted agrarian traditions with a steady, pragmatic approach to economic growth and development.
Prosser fosters a cultural identity forged by the shared labor of the harvest and the deep-seated pride of those who work the land. Prosser City Park serves as an essential gathering place, providing a central venue for residents to congregate beneath the shade of mature trees. The town hosts various seasonal festivals that honor its agricultural heritage, bringing a palpable energy to the streets during the height of the picking season. While the pace of daily life remains measured and deliberate, the community retains a sharp awareness of its place within the wider landscape. Notable figures such as the professional football player Brock Huard have roots in this environment, reflecting the quiet strength and discipline often found among those raised in such an open, expansive setting.

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.
