How to Use This Green Mountain, Iowa Map
This interactive map shows the street layout and satellite imagery for Green Mountain, 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 Green Mountain.
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 Green Mountain, Iowa
Green Mountain is a locality in Marshall County, Iowa, United States. It is a small community with a population of 113. The population density is 63.6 people per km². Green Mountain is located at 42.1017°N, 92.8205°W. It observes the Central Time (America/Chicago) timezone. ZIP codes: 50632, 50158.Green Mountain manifests as a quiet intersection of horizon and furrow, defined by the persistent, rhythmic flow of Nickolson Creek as it carves a path through the deep, black earth. It lies 5.8 miles northeast of Marshalltown, IA (from Marshalltown, IA: bearing 51°T), and is situated 15.6 miles northwest of Tama. The landscape here is a study in vast, horizontal patience, where the expansive fields of corn and soybeans stretch toward the sky until the light turns thin and amber at the close of day. In the distance, the faint, jagged silhouette of Mormon Ridge suggests a geological complexity that contrasts with the immediate, flat intensity of the prairie floor. During the quiet hours of a humid summer afternoon, the air holds a heavy, sweet stillness, as if the land itself were listening for the shifting of the wind across the stalks.
Agricultural cycles dictate the pulse of Green Mountain, grounding the inhabitants in a long-standing tradition of stewardship that honors the stubborn fertility of the soil. While the economy remains tethered to the rhythmic demands of harvest and planting, a quiet, literate civility permeates the local character, reflecting a heritage shaped by generations of settlers who valued endurance over ornament. Residents often seek the solitude of Furrow Access to observe the seasonal changes in the tallgrass, or travel the short distance to Union Grove Lake when the heat demands the cooling presence of water. Life in Green Mountain proceeds with an unshowy consistency, a steady accumulation of days where the primary labor is the tending of a landscape that is both profoundly productive and stubbornly serene.

About This Green Mountain Map Page
This page provides an embedded street and satellite map of Green Mountain, Iowa. Coordinates: 42.101654, -92.820477. 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 Green Mountain includes the ZIP code (50632, 50158), telephone area code (319, 515), county seat of Marshall County (Marshalltown), and school district assignment (GMG 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.
