Explore Altmar, New York, 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 Altmar, New York. 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 New York 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 Altmar.
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.

Altmar emerges from the dense, damp woodlands of the interior where the Salmon River carves a persistent path through the limestone bedrock. It lies 23.8 miles north-northeast of Cicero, NY (from Cicero, NY: bearing 14°T), and is situated 4.7 miles south-southeast of Richland. The landscape surrounding Altmar is defined by the heavy, seasonal weight of the snowbelt, which softens the sharp edges of the terrain and feeds the quiet stillness of Bud Lee Pond. Within the boundaries of the Lower Salmon River State Forest, the earth holds a deep, mossy scent, and the air remains cool even as the summer sun filters through the canopy of maple and hemlock. Four miles away, the Salmon River Falls tumbles over its rocky precipice, a concentrated force of water that dictates the rhythm of the local geography. Far to the south, the Appalachian Mountains suggest a distant, hazy silhouette against the horizon, though they remain entirely removed from the immediate, wooded isolation of this northern plateau.
Economic life in Altmar has long been tethered to the vitality of the surrounding wilderness and the seasonal migrations that define the local calendar. The presence of the Salmon River has historically dictated the settlement’s pace, drawing those who find a particular, solemn focus in the pursuit of the river's bounty. While the modern world moves with a frantic, digitized urgency, Altmar maintains a deliberate, quiet character, shaped by the cycles of the forest and the persistent flow of the water. The local industry remains modest and grounded, favoring the preservation of natural resources over rapid expansion, which keeps the atmosphere suspended in a state of quiet, rural endurance. This legacy of environmental reliance ensures that the daily life of the residents remains closely aligned with the changing light of the seasons and the enduring, rugged temperament of the landscape.

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.
