How to Use This Diagonal, Iowa Map

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

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.

Diagonal unfolds across the Iowa landscape as a quiet expanse of tilled earth and sky, where the horizon stretches wide enough to hold the weight of the clouds. It lies 55.7 miles southwest of Indianola, IA (from Indianola, IA: bearing 227°T), and is situated 17.2 miles south of Creston. The terrain here is defined by the steady, rhythmic rise and fall of the prairie, a land of deep, dark soil that seems to absorb the golden light of late afternoon until the fields glow with a rich, copper hue. Only a mile away, the Grand River carves a serpentine path through the surrounding woodland, its currents carrying the silty history of the plains toward distant basins. At the edge of the property line, the Fogle Lake Wildlife Management Area provides a sanctuary for native grasses and local fauna, while the shimmering surface of Sun Valley Lake remains a nearby presence, reflecting the vast, unobstructed dome of the Midwestern heavens.

Agriculture serves as the pulse of Diagonal, with the seasonal cycles of corn and soybeans dictating the pace of life and the movement of heavy machinery along the grid of rural roads. The heritage of the region is written in the sturdy, unadorned architecture of the farmsteads and the resilient character of families who have worked this soil for generations. While the modern world moves with a frantic urgency, Diagonal maintains a deliberate, measured gravity, favoring the quiet satisfaction of a well-maintained fence line and the honest labor of the harvest. There is a particular clarity to the air here, a crispness that sharpens the edges of the barns and silos against the gray winter light, grounding the inhabitants in a place that asks for little but offers a deep, enduring sense of belonging.

About This Diagonal Map Page

This page provides an embedded street and satellite map of Diagonal, Iowa. Coordinates: 40.809435, -94.342179. 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 Diagonal includes the ZIP code (50845), telephone area code (319), county seat of Ringgold County (Mount Ayr), and school district assignment (Diagonal Community 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.
