Sun and shade

Hours of direct sun

NESWN 10:18 am · on the pitch

The horizon around site 100, east on the left, south in the middle, west on the right, with the sun's path on 24 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 8.2° above the horizontal to the northeast. 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 8.2° above level, to the northeast.

On the March equinox direct sun reaches the pitch at 7:20 am and leaves it at 7:24 pm: 12 h 6 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.

Lay of the land

The ground

The elevation model puts the pitch at 1,211 ft, on an upper slope. At 2.8° the ground is level enough that it does not face anywhere in particular.

Within the 1.2 km square sampled around it, the site stands 315 ft above the lowest ground in that square, which lies 0.5 mi southeast and 374 ft below the high ground 0.5 mi northeast.

The nearest mapped water is an unnamed run 0.1 mi southeast. OpenStreetMap maps the channel but has no name for it. Treat any water from it before drinking.

What happened near here

Many of the oldest farmhouses around Green Ridge are log, and most of the logs are hidden under later weatherboard, insulbrick or asbestos shingle.

Log houses and the families who farmed the ridges · 1780s–1910s · about 1.5 mi from this site, at Hose Log House

Before the forest there were farms, most of them small. The Maryland Historical Trust's surveys of the 1970s–2000s recorded dozens of farmhouses in and around Green Ridge, and the oldest of them are log. Along Maniford Road and Town Creek stand the Athey house of about 1804, a one-room log house on a farm the Atheys worked for nearly a century; the McLaughlin house of about 1815, recorded as one of the finest two-story log houses in the county; the Wigfield house of about 1820, set directly on the ground without a foundation; the Amick 'saddlebag' house of about 1825, two log pens sharing one stone chimney; and the Hose house of about 1834. On Town Creek a sandstone chimney is all that stands of a stone house built in 1787. Log building went on for a century because timber was close at hand. Barney and Samuel Shipley each built a log farmhouse within a mile of the Pennsylvania line after buying land in 1881, and the Whorton and Carder houses date from the 1890s. Most were later covered in weatherboard, insulbrick or asbestos shingle, so the logs survive out of sight. The surveys keep the names: David Mann, a Pennsylvania-born farmer who had twenty-two children; George W. Hymes, who built his own house, windows included, at seventeen in 1910; and the Lashleys, whose farm near Flintstone was paid for in 1783, its survey records, 'with slaves'.

What is left to see: Most of these houses are private and several are posted; see them only from the public road. The log house near Kasecamp Road is on state land but was deteriorated and boarded when surveyed; do not enter.

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.
What happened near here comes from published history: Maryland Historical Trust survey forms, Maryland DNR, the National Park Service and the C&O Canal's historians, and the records themselves. Each story lists its own sources; a story appears only when one of its catalogued places is within about two miles, and the distance is measured, not estimated. All the history sources.
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.
