Explore Riverside, Oregon, 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 Riverside, Oregon. 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 Oregon 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 Riverside.
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.

Riverside occupies a stretch of high, arid land where the Umatilla River cuts a persistent path through the earth. It lies 2.5 miles east of Pendleton, OR (from Pendleton, OR: bearing 85°T), and is situated 28.2 miles south-southwest of Whitman. The landscape surrounding Riverside is defined by the expansive, open reach of Gopher Flats, a basin that catches the light in long, pale ribbons as the sun dips toward the horizon. To the far distance, the jagged silhouettes of the Blue Mountains rise against the sky, their peaks often holding a faint, dusty violet hue that shifts with the passing seasons. The air here carries a dry, crisp weight, stripped of humidity and smelling faintly of sagebrush and sun-warmed stone, grounding the senses in the quiet immensity of the interior plains.
History remains a quiet presence in Riverside, as the Oregon Trail National Historic Trail winds through the terrain, marking the heavy, worn tracks of those who moved across this country long ago. The local economy stays tied to the rhythms of the land, with agriculture and the seasonal demands of the soil dictating the pace of life. A few miles away, the waters of McKay Reservoir provide a steady, still mirror for the vast sky, offering a stark contrast to the moving current of the river nearby. Days in Riverside unfold with a deliberate, steady consistency, where the focus rests on the work at hand and the slow, inevitable turn of the year, untouched by the frantic pulse of more crowded centers.

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.
