Sun and shade

Hours of direct sun

NESWN 11:00 am · on the pitch
The horizon around site 35, east on the left, south in the middle, west on the right, with the sun's path on 22 October: amber where it reaches the pitch, dashed where the ridge hides it. The fainter arcs are the other dates the site’s 360 view shows. Its highest ridge stands 4.3° above the horizontal to the southeast. Sampled 144 times out to 9 km from the USGS elevation survey. Every sun time on this page is computed against this line.

Hours of direct sun on the pitch by month; the grey behind each bar is the full day the almanac gives with no ridges in the way.

The tallest ground on this site's horizon stands 4.3° above level, to the southeast.

On the March equinox direct sun reaches the pitch at 7:40 am and leaves it at 7:18 pm: 11 h 40 m of it, against 12 h 12 m of daylight on an open horizon.

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

The ground

The elevation model puts the pitch at 1,024 ft, on an upper slope tilted about 4.9° to the west.

Within the 1.2 km square sampled around it, the site stands 145 ft above the lowest ground in that square, which lies 0.4 mi north and 86 ft below the high ground 0.5 mi southeast.

The nearest mapped water is Deep Run, 1.1 mi southeast.

Where these numbers come from

Provenance

Most of this page is computed from public data; the lines marked Community come from campers. The computed data was last rebuilt from its sources on 28 September 2026.

  • 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 its elevation tiles.
  • Roads and watercourses come from OpenStreetMap contributors, licensed ODbL, as mapped at that rebuild. A road can wash out or close after it.
  • Sun times are when the sun clears that measured skyline, computed with the NOAA Solar Calculator equations. They are for 2026 and shift by a minute or two from year to year.
  • The pin comes from the Maryland Department of Natural Resources campsite GIS layer.
  • Evenings here are the same sun times, on four dates of the year: when the sun drops behind this pitch's measured skyline, against the open-horizon sunset.
  • The modeled view and the 360 are rendered from a 3D model of the forest, from the pitch, through a whole day in each of five seasons. The ground is the same elevation data plus lidar. Tree heights come from lidar; the species mix and tree form come from US Forest Service inventory plots in Allegany County, so no tree here was surveyed individually. The tent, table and fire ring are the same stand-ins at every site. When a photograph from the site, ours or one a camper sends, shows the model is wrong about where the pitch is or what the ground is like, the model is corrected and the 360 is rendered again. How the 360 is made.
  • Character tags and field notes come from campers. They are judgements rather than measurements.
  • Availability is not on this page because nothing publishes it. The app shows what the last photograph of the sign-up sheet said, and how old that photograph is.
