How to Use This Walnut, California Map

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

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.

Walnut occupies a terrain of quiet ridges and sloping meadows that define its inland character. It lies 2.3 miles east-northeast of South San Jose Hills, CA (from South San Jose Hills, CA: bearing 77°T), and is situated 6.9 miles west-southwest of Pomona. Lemon Creek carves a path through the landscape, providing a seasonal rhythm to the earth that shifts with the light. In the distance, the San Gabriel Mountains loom against the horizon, their peaks often catching the sharp, golden quality of the afternoon sun. Residents find respite in the local grounds of Creekside Park, where the dry, fragrant air of the inland plains persists. The nearby terrain of Powder Canyon offers a rugged contrast to the more manicured stretches of the neighborhood, grounding the environment in a stark, natural permanence.

Walnut carries a history rooted in the transition from open grazing lands to a structured residential community. The local economy shifted steadily away from early agricultural pursuits, eventually giving way to a suburban landscape that favors quiet commerce and professional services. Small industries and business hubs now populate the space where orchards once thrived under the bright, unfiltered sun. This evolution reflects a broader regional tendency to repurpose the land for modern needs while maintaining the integrity of the original parcel lines. The labor of those who labored here in decades past remains visible in the sturdy infrastructure that supports the current pace of life.

Walnut maintains a cultural character defined by a deliberate balance between academic pursuit and a calm, domestic atmosphere. Notable landmarks include the educational institutions that anchor the social life of the residents, fostering a spirit of intellectual inquiry. High-achieving schools and the presence of Mount San Antonio College ensure that the youth are consistently engaged in their personal and professional development. While the pace of the day remains steady and measured, the occasional community event brings neighbors together to celebrate the shared identity of the region. Notable individuals like the actor and musician Steve Martin once walked these paths, leaving behind a trace of creative energy that still resonates in the quiet corners of the neighborhood.

About This Walnut Map Page

This page provides an embedded street and satellite map of Walnut, California. Coordinates: 34.037195, -117.855606. Live weather conditions are sourced directly from the National Weather Service. Real-time local and world news feeds keep the page current.

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.
