How to Use This Third Lake, Illinois Map

This interactive map shows the street layout and satellite imagery for Third Lake, 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 Third Lake.

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.

Third Lake defines the horizon with its quiet, glacial basin, where the water mirrors the shifting Midwestern sky in shades of slate and bruised plum. It lies 2.1 miles northwest of Gages Lake, IL (from Gages Lake, IL: bearing 317°T), and is situated 4.0 miles east of Round Lake Beach. Mill Creek snakes through the landscape, feeding the low-lying terrain with a persistent, rhythmic vitality that keeps the soil dark and rich. Beyond the immediate water’s edge, the Rollins Savanna Forest Preserve stretches out, a vast expanse of restored prairie grasses that sway in the wind like a golden sea, offering a reminder of the land before the plow. In the cool air of autumn, the light here grows thin and sharp, catching the edges of the reeds and turning the surface of Third Lake into a polished, dark glass that holds the day’s final warmth.

The economy of Third Lake remains tethered to the slow, deliberate pulse of its natural surroundings, where the legacy of early settlers who recognized the fertility of these plains still informs the stewardship of the land. While the modern world moves with a frantic, industrial hum, life in this locality retains a measured pace, favoring the preservation of wide-open spaces over the density of the grid. Residents look toward the distant, hazy heights of Leahy Hill or find solace in the quietude of the local preserve, far removed from the clamor of the major hubs. It is a place that values the steady, unspoken bond between the inhabitants and the geography, maintaining a character that is defined less by the grand gesture and more by the enduring presence of the creek and the vast, unburdened sky.

About This Third Lake Map Page

This page provides an embedded street and satellite map of Third Lake, Illinois. Coordinates: 42.37391, -88.010912. 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 Third Lake includes the ZIP code (60030), telephone area code (312, 773), county seat of Lake County (Waukegan), and school district assignment (Grayslake Community High School District 127).

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.
