Explore Union Gap, 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 Union Gap, 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 Union Gap.
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.

Union Gap emerges from the arid earth where the Yakima River carves a deliberate path through the landscape. It lies 3.4 miles south-southeast of Yakima, WA (from Yakima, WA: bearing 155°T), and is situated 3.8 miles south-southwest of Terrace Heights. The terrain surrounding Union Gap is defined by the sharp transition between the open expanse of the Moxee Valley and the distant, jagged silhouette of the Cascade Range that marks the horizon. Sunlight here possesses a distinct, heavy clarity, illuminating the sagebrush and the dry, golden grasses that cling to the slopes. On quiet afternoons, the wind carries the scent of sun-warmed soil across the plains, grounding the senses in the stark reality of the interior. Residents find a simple, persistent beauty in the way the light fades behind the distant peaks, casting long, violet shadows across the basin.
Union Gap grew from the rugged necessities of early irrigation and the promise of fertile soil reclaimed from the desert. The local economy remains deeply tied to the bounty of the land, with agriculture and fruit packing houses forming the backbone of regional industry. Rows of orchards stand as orderly, green soldiers against the heat, their rhythmic patterns a testament to the labor required to sustain life in this climate. Commerce flows through the corridors of Union Gap, where the exchange of goods keeps the pulse of the community steady and predictable. Hard work is the primary currency here, reflected in the weathered hands and the pragmatic attitudes of those who manage the seasonal harvests.
Cultural life in Union Gap balances the quietude of rural persistence with the occasional bustle of local gatherings. Loudon Park offers a necessary space for community assembly, providing a verdant reprieve where the air feels slightly cooler beneath the trees. A short distance away, the waters of Rotary Lake offer a subtle respite for those seeking a moment of stillness away from the hum of the highway. While the pace of life remains slow, the spirit of the area is defined by a deep-seated resilience and a straightforward approach to the passing seasons. No towering figures of global fame claim this ground as their birthplace, as the character of Union Gap is built instead upon the collective efforts of the people who reside there.

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.
