The ground
The elevation model puts the pitch at 995 ft, on an upper slope. At 0.7° 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 166 ft above the lowest ground in that square, which lies 0.4 mi south and 71 ft below the high ground 0.4 mi west.
The nearest mapped water is an unnamed run 0.2 mi east. OpenStreetMap maps the channel but has no name for it. Treat any water from it before drinking.

When the Mason–Dixon line was resurveyed in 1900, some of the unused English boundary stones turned up as doorsteps and horse blocks in western Washington County.
Resetting the Mason–Dixon stones, 1900–1903 · 1900–1903 · about 1 mi from this site, at Mason-Dixon Line: Milestone No. 151
The forest's northern edge is the Mason–Dixon Line. Mason and Dixon ran it here in 1766–67, but their stone markers, cut in England from oolitic limestone, went no farther west than Sideling Hill, because wagons could not haul them on. West of Sideling Hill the line was marked by mounds of earth and stones and wooden posts, and over a century many were ploughed down, washed out or lost in fallen timber. In 1900 Maryland and Pennsylvania agreed to resurvey their common boundary with the help of the U.S. Coast and Geodetic Survey. The engineers were told to reproduce Mason and Dixon's line exactly, not to correct it, and to save every original stone they could. They found that some unused English stones had been left in western Washington County and had ended up as doorsteps, horse blocks and building stone; they recovered what they could and set them in gaps in the line. Where nothing old could be found they set new posts of magnesian marble from the Beaver Dam quarry in Baltimore County (the MHT forms call it Cockeysville marble), cut with P and M and the dates 1766 and 1902. The last was set in August 1903. Along the forest, stone 152 on Ragged Mountain is an original crown stone, carved with the Penn and Calvert arms and set in the 1767 mound; the 1909 report called it the westernmost of the old monuments then on the boundary.
What is left to see: Several stones stand beside public roads that cross the line north of the forest; most are on private land or in the woods. Look from the road, and leave the stones and the old mounds undisturbed.
“...some were deliberately injured or destroyed by ignorant farmers who seemed to feel a serious injury from the loss of the products of the little space of land occupied by them, and some were badly damaged, in a few cases even removed entire, by relic hunters.”

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.
