Shortlist · Green Ridge State Forest, Maryland

Campsites with the most open sky

22 of the 99 campsites with a page qualify.

In a ridge-and-valley forest the thing between you and the stars is usually the ridge. These are the pitches with the least of it in the way: the sky above them is open almost to the horizon in every direction.

The app draws the measured skyline behind the night sky for whichever site you open.

Independent, free, and built by campers. Not a DNR service.

Booking
None. Sites are first come, first served.
Fee
$10 a night for a standard site, $20 for a group site, paid at headquarters. Maryland DNR.
Check in
Sign the sheet at headquarters when you arrive, then go to the site.
Is it free tonight?
This page cannot know. The app shows what the sign-up sheet last showed, with the photo's age.
What put a site on this list

97 per cent or more of the sky above the pitch is clear of the skyline — the top quarter of the forest, where the median site is 94.5 per cent.

The test
Open-sky fraction 0.97 or higher, from the horizon profile measured around each pitch.
Where it comes from
The skyline is traced from the USGS 3DEP elevation model in every direction from the pitch, and the open fraction is the share of the hemisphere left above it.
What it does not mean
This is horizon openness, not darkness. It is how much sky the land leaves you, measured off a terrain model. Nobody has metered sky brightness at these sites and no Bortle class is claimed. The model sees ground, not trees: a pitch under a closed canopy still counts as open sky here.

The other shortlists

Every list is built from the same data, and a site can appear on several of them.

Where these numbers come from

Provenance

This list is generated from open data at build time, not compiled by hand. Nothing on it is a recommendation: it is a test, run over every campsite, with the test written at the top of the page so you can disagree with it.

  • Elevation, landform, slope, the horizon profile, sun times and the steepest grade on the approach come from the USGS 3D Elevation Program (3DEP).
  • Roads, surfaces and watercourses come from OpenStreetMap contributors, licensed ODbL.
  • Campsite coordinates and sections come from the Maryland Department of Natural Resources campsite layer.
  • Pitch tags — room for a trailer, secluded, a view — 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.

Independent, free, and built by campers. Not a DNR service. Greenridge is not affiliated with the Maryland Department of Natural Resources or any government agency, and the forest’s own rules always win.
