Explore Derrick City, Pennsylvania, 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 Derrick City, Pennsylvania. 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 Pennsylvania 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 Derrick City.
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.

Derrick City occupies a rugged stretch of the Allegheny Plateau where the land rises into dense, timbered slopes and deep, narrow depressions. It lies 37.5 miles north of Saint Marys, PA (from Saint Marys, PA: bearing 359°T), and is situated 3.9 miles east-northeast of Bradford.
Foster Brook carves a persistent path through the local terrain, its waters threading past the quiet outskirts and providing a constant, low-frequency hum against the stillness of the woods. Only two miles distant, the terrain dips into the quiet shadows of Totten Hollow, a basin that holds the cool, damp air of the morning long after the sun has crested the ridges. Residents often find their way toward the expanse of Unknown Park, which sits a single mile away, offering a quiet, unadorned space where the trees grow thick and the ground remains soft with leaf litter. Even the light here feels different, filtered through a canopy that softens the harsh glare of the afternoon into a muted, silver-gray glow that settles over the earth.
Derrick City emerged from the raw ambition of the early oil boom, a period that left its mark on the local character through a stubborn, industrious resilience. While the frantic pace of the derricks has long since faded into the quiet of history, the economy remains tethered to the land, shaped by the persistent work of those who know how to extract value from the stubborn soil. The influence of the oil fields is still visible in the scattered remnants of infrastructure that dot the landscape, serving as a reminder of an era that demanded much from the earth. Four miles away, Number Four Reservoir maintains a steady, reflective presence, its surface mirroring the changing seasons and the slow, deliberate pace of the days. Life in Derrick City follows the rhythm of these unchanging hills, where the legacy of the past is not a museum piece but a quiet, steady pulse beneath the feet of those who walk these paths today.

Detailed location data for Derrick City includes the ZIP code (16701, 16727), telephone area code (215, 223, 267, 272, 412, 445, 484, 570, 582, 610, 717, 724, 814, 835, 878), county seat of McKean County (Smethport), and school district assignment.
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.
