Explore St. Lucas, Iowa, 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 St. Lucas, 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 St. Lucas.
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.

St. Lucas emerges from the expansive geometry of the Iowa prairie, where the horizon serves as a flat, unyielding line against the vast Midwestern sky. It lies 36.1 miles northeast of Waverly, IA (from Waverly, IA: bearing 49°T), and is situated 9.6 miles northwest of West Union. Bass Creek carves a quiet, persistent path through the surrounding fields, its water reflecting the shifting hues of the seasons as it meanders past the town’s periphery. Beyond the immediate reach of the valley, the earth rises in subtle, rhythmic swells, a precursor to the more pronounced terrain that eventually yields to the distant silhouette of the Lansing Ridge. The sunlight here possesses a particular clarity, catching the dust motes above the tilled soil and illuminating the deep, mineral-rich color of the earth that defines the character of the landscape.
St. Lucas maintains a deep connection to its agricultural roots, with the economy remaining anchored in the stewardship of these fertile plains and the seasonal cycles of corn and soybean production. The heritage of the area is etched into the local architecture and the enduring patterns of daily life, reflecting the industrious spirit of early settlers who organized their lives around the rhythms of the land. Visitors often find a curious, miniature sort of peace at the Smallest Church Park nearby, or venture slightly further to enjoy the quietude of Lake Meyer. While the dense, timbered refuge of the Fort Atkinson State Preserve provides a contrast to the open fields, the essence of St. Lucas remains centered on the patient, deliberate labor of those who work the soil and keep the town’s quiet traditions alive.

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.
