Primitive site · Green Ridge State Forest, Maryland

Campsite 37

974 ft east-facing ridge crest

Site 37 is one of the primitive, first-come campsites scattered through Green Ridge State Forest in western Maryland. It sits at 974 ft on an east-facing ridge crest, with White Sulphur Pond 0.8 mi northeast. The drive in is rated “High clearance”.

Lay of the land

The ground it sits on

The elevation model puts the pitch at 974 ft, on a ridge crest tilted about 8.2° to the east.

Within the 1.2 km square sampled around it, the site stands 202 ft above the lowest ground in that square, which lies 0.5 mi northeast.

The nearest mapped water is White Sulphur Pond, 0.8 mi northeast.

Sun and shade

What the ridges do to its light

The tallest ground on this site's horizon stands 4.5° above level, to the west.

On the March equinox direct sun reaches the pitch at 7:34 am and leaves it at 6:58 pm: 11 h 26 m of it, against 12 h 12 m of daylight on an open horizon.

That gap — 46 min — is what the ridges take, and it is rarely taken evenly off both ends of the day.

Across the year the pitch runs from 14 h 22 m of direct sun at the June solstice down to 8 h 46 m at the December solstice.

Direct sun on the pitch, 2026. “Open horizon” is what the same day would give with no ridges in the way.

Getting there

High clearance

Clearance genuinely needed — not a road for a low car.

You arrive on an unnamed spur, which OpenStreetMap classes as a forest track.

3.6 mi of unpaved driving stands between the last pavement and the site.

The steepest stretch of that final approach measures 25.6% on the elevation model, climbing 244 ft in total.

The pitch itself sits 140 ft from that road, which is how far the cooler gets carried.

Where these numbers come from

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.
