Campsite 83
1,034 ft upper slope
Site 83 is one of the primitive, first-come campsites scattered through Green Ridge State Forest in western Maryland. It sits at 1,034 ft on an upper slope, with Fifteenmile Creek 0.5 mi west. The drive in is rated “Gravel road”.
The ground it sits on
The elevation model puts the pitch at 1,034 ft, on an upper slope — at 1.6° the ground is near enough level that it does not meaningfully face anywhere.
Within the 1.2 km square sampled around it, the site stands 413 ft above the lowest ground in that square, which lies 0.5 mi northwest and 155 ft below the high ground 0.5 mi northeast.
The nearest mapped water is Fifteenmile Creek, 0.5 mi west.
What the ridges do to its light
The tallest ground on this site's horizon stands 5.5° above level, to the northeast.
On the March equinox direct sun reaches the pitch at 7:30 am and leaves it at 7:22 pm: 11 h 54 m of it, against 12 h 12 m of daylight on an open horizon.
The ridges cost it under twenty minutes that day — for this forest, an unusually open sky.
Across the year the pitch runs from 14 h 30 m of direct sun at the June solstice down to 8 h 56 m at the December solstice.

Gravel road
Forest gravel. Fine in a car, taken slowly.
You arrive on an unnamed spur, which OpenStreetMap classes as a forest track.
0.6 mi of unpaved driving stands between the last pavement and the site.
The steepest stretch of that final approach measures 12.9% on the elevation model, climbing 221 ft in total.
The pitch opens directly off the road — no carry.

Provenance
Everything on this page is derived from open data at build time. None of it is anyone's opinion, and none of it was measured on foot.
- Elevation, landform, slope, aspect, contours, the horizon profile and the steepest grade on the approach come from the USGS 3D Elevation Program (3DEP), read from terrain-RGB tiles at zoom 14.
- Roads and watercourses come from OpenStreetMap contributors, licensed ODbL.
- Sun times are computed from the NOAA Solar Calculator equations against that measured skyline — when the sun clears the ridge, not when an almanac says it rises. Figures are for 2026; they shift by a minute or two from year to year.
- Campsite coordinates come from the Maryland Department of Natural Resources campsite GIS layer.
- Character tags and field notes come from campers, and are the only thing here that is a judgement rather than a measurement.
- Availability comes from nowhere, because there is no source for it. See above.
Greenridge is an independent community project. It is not affiliated with the Maryland Department of Natural Resources or any government agency, and the forest's own rules always win.
