How to Use This Dayton, Illinois Map
This interactive map shows the street layout and satellite imagery for Dayton, Illinois. 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 Illinois 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 Dayton.
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.

About Dayton, Illinois
Dayton is a locality in LaSalle County, Illinois, United States. It is a small community with a population of 528. The population density is 109.8 people per km². Dayton is located at 41.3915°N, 88.7992°W. It observes the Central Time (America/Chicago) timezone. ZIP codes: 61241, 61350.Dayton manifests as a quiet confluence of limestone and water, defined by the persistent, rhythmic passage of the Fox River as it carves through the Illinois bedrock. It lies 3.7 miles northeast of Ottawa, IL (from Ottawa, IL: bearing 43°T), and is situated 8.4 miles east-southeast of LaSalle. The landscape surrounding Dayton unfolds in broad, deliberate strokes, where the earth yields to the steady erosion of the riverbed and the encroaching greenery of the Dayton Bluffs Preserve. In the golden light of late afternoon, the shadows lengthen across the plains, imbuing the woods with a muted, earthen depth that feels ancient and undisturbed. The air here holds the dry, crisp weight of the interior continent, far removed from the brine of distant shores, carrying instead the scent of damp soil and the seasonal transition of prairie grasses.
Historical echoes of Dayton persist in the remnants of its early industrial ambitions, where the power of the water was once harnessed to turn the gears of local milling and manufacture. While the modern economy has shifted away from the water-driven industry of its founding, the legacy of that labor remains etched in the stoic architecture and the persistent, unhurried pace of daily life. The regional landscape is punctuated by the distant, industrial silhouette of the LaSalle County Nuclear Station Cooling Pond, a stark marker of contemporary energy, and the rise of Buffalo Rock, which stands as a silent sentinel over the plains. Even in the shadow of such landmarks, Dayton maintains a steady, internal gravity, grounded by the steady flow of the Fox River and the sprawling, quiet fertility of the surrounding farmland.

About This Dayton Map Page
This page provides an embedded street and satellite map of Dayton, Illinois. Coordinates: 41.391523, -88.799197. 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 Dayton includes the ZIP code (61241, 61350), telephone area code (847, 224, 815), county seat of LaSalle County (Ottawa), and school district assignment (Ottawa Township High School District 140).
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.
