Mason-Dixon Line Western Crossings



Markers I've visited along the Mason-Dixon Line

Though my initial research was not aimed at finding stone markers on the Mason-Dixon Line, I've been fortunate enough to uncover quite a few -- 32 is my current total (November, 2008). Below is a brief description of where I've been on The Line. Note that these stones were placed either by Mason and Dixon or those who followed during resurveys or related surveys. No "highway" markers are included in the count.


1. Intersection of Tangent Line and Transpeninsular Line. The stone that marks the southwest corner of Delaware. The western border of Delaware (the Tangent Line) is part of the Mason-Dixon survey. The smaller stones were placed by earlier surveys. See the page dedicated to this location here.

NOTE: See my page of the eastern end of the Transpeninsular Line at Fenwick Island, Del. This line, Delaware's southern border, is not a part of the Mason-Dixon Line, though Mason and Dixon certified its accuracy.

2. Pa. Route 163 (Mason-Dixon Road) near Interstate 81. This marker lies along the highway just across from the exit ramp of I-81 north.

3. Along the railroad tracks off Pa. Route 163. A broken marker along a fence line and at the edge of railroad tracks in the village of Mason and Dixon, Pa.

4. Mason-Dixon Crownstone (USGS Stone No. 105). This beautiful stone bearing the Calvert family and the Penn family arms lies on private property just east of the end of Pa. Route 163 at The Line. Thanks so much to the kind property owner who gave us passage to photograph the stone.

5. Warfordsburg, Pa. This Mason-Dixon marker lies to the east side of a secondary road just to the east of Interstate 70. There is a nearby gas line station and a broken state line highway marker.

6. Pa. Route 26. The Route 26 marker lies on the east side of the road north of Piney Grove, Md.

7. Pa. Route 96/Md. Route 35. Stone lies in a churchyard at Ellerslie, Md.

8. Pa. Route 160/Md. Route 47. This stone lies perilously close to the highway and an intersecting secondary road.

9. Delbrook Lane. The stone lies at the edge of a treeline in a field about a mile west of Pa. Route 160.

10. Hetrick Road (Md.)/Resh Road (Pa.). I'm kneeling at this somewhat hidden marker close to the road north of Hi Point, Md. off the National Road, and north-northwest of Grantsville, Md.

11. Glover Road (Pa.)/Smearman Road (Md.). A curious and friendly kitty crosses The Line along this narrow blacktop road just to the west of Friendsville-Addison Road.

12. The National Road. Where historic U.S. Route 40 crosses the Mason-Dixon Line.

13. Behind Dixie Motel. A pile of stones surrounds this marker in the woods off U.S. Route 40. The rock mound likely is an original. The motel is in Somerset County, Pa.

New! 14. Mill Run Road. A stone I missed on a previous visit that's actually very easy to find. This marker is a few yards east of Mill Run Road near the intersection with Frazee Road. This area is just to the east of the Youghiogheny Lake.

15. The Sinclair Stone. This marker was placed on the Mason-Dixon Line by Cephas H. Sinclair during the 1883-85 resurvey. It was meant to mark the spot where Maryland, West Virginia and Pennsylvania meet, but it is too far east.

16. The Tripoint Stone. Just west of a large powerline, this is the official spot where Maryland, West Virginia and Pennsylvania meet.

17. The Michler Stone. Placed by Nathaniel Michler at what was thought to be the Tripoint, but this one is too far west. This stone is a few feet to the east of Pa. Route 281 and W.Va. Route 26.

18. Wirsing School Road. This stone lies in at the edge of a treeline in a rural area to the southeast of Pennsylvania's Quebec Run Natural Area. Looking west in this view, with West Virginia on the left.

19. Skyline Drive. Behind a Columbia Gas Co. remote location, this stone recently was set in concrete to thrwart attempts at stealing it. Many thanks to Ray Griffith and his son Brian for providing me access to the marker. Pennsylvania is to the right in this shot.

20. Route 857. The marker is the first at foot of Chestnut Ridge. It lies on a slight wooded slope between two dirt lanes. Someone has decorated it with a ribbon.

21. Bunker Hill Road. This stone is just south of the road in the woods and east of Lake Lynn Dam. The road is visible through the trees behind me; it skirts The Line in this area.

22. Mine Road. A fenced cow pasture surrounds this marker, which is not plotted on most topo maps I?ve seen. First stone west of Lake Lynn Dam. A family of friendly bovines live here. New! A more recent closeup photo of the stone, taken in Nov. 2008, when the cows were not guarding the pasture.

23. Davidson. The woods hide this unusual marker hidden behind a home in Fayette County, Pa.; southeast of Point Marion.

24. New! U.S. Route 119/Point Marion. Hidden in the woods just to the east of U.S. Route 119 not far from Point Marion, this stone is the first I've found heading east that was set in 1885. To the west, all stones were set in 1883. Looking south in this view toward West Virginia.

25. Old Taylorstown Road. This stone may have been moved from its original location to save it from strip mining. It lies just to the east of Old Taylorstown Road (W.Va.)/Matthews Road (Pa.) on the property of Warren Lilly.

26. Mount Morris. Next to a telephone pole near the top of a hill on property owned by my friend Bill Strosnider. Bill operates Mason-Dixon Woodworks; if you meet him at a craft show, I highly recommend his work.

27. Brown's Hill. The historic site where the Mason and Dixon survey (but not The Line) were stopped by Indians in October, 1767.

28. Blacksville, W.Va. This marker lies west of the small town a few feet behind a Consolidated Coal Co. sign in a small patch of woods.

29. Hacklebender Run. A difficult-to-find marker near the top of a ridge; Chad Hahn kindly took me to this marker on his family's property. It lies just to the southwest of the intersection of Wilson Road and Hacklebender Run Road in Greene County, Pa.

30. Turkey Hill Road. Residents Jimmy Rizor and John Neeley directed me to this stone lies in a line of trees along a fence line on a hill above the road; southwest of the village of Ned, Greene County, Pa.

31. Penultimate Stone. The last stone before The Cornerstone visited with John Neeley. This stone is accessible off Young Road and the last driveway in Pennsylvania before the western border, the Ellicott Line.

32. The Cornerstone. The monument at Pennsylvania's southwest corner. At 5 degrees in longitude from the Delaware River, this is the spot Mason and Dixon were trying to reach; hence, this can be considered the end of the Mason-Dixon Line. In this photo added March 6, 2008, a hiker can see how the Cornerstone would look when you reach the end of the Mason-Dixon Line. Note the "WV" and the "P" on the face of the stone. Finally, here is a view of the Cornerstone as seen from the southwest, obviously in West Virginia. The Cornerstone also markers the border of Marshall and Wetzel counties in West Virginia.



Missing markers: I continue to learn of markers once placed on The Line that were moved or destroyed. Here are two such instances:

The marker between Hero and Jollytown, northeast of the Mount Tabor Church, W.Va., is said to have been destroyed by vandals. The marker was at 39 degrees, 43 minutes 16 seconds north; 80 degrees 20 minutes 21 seconds west. A member of the family that owns the property gave me this sad news in 2005.

Neil "Chissy" Chisler, who owns the auto repair business just inside Pennsylvania at Macdale, W.Va., told me the story he heard of a farmer who pulled out one of the two markers east of Brave, Pa. As the story goes, the farmer apparently did not like the stone sitting in the middle of his field. The stone is said to be on the site, but not in its proper position which, I believe, is at 39 degrees, 43 minutes 16 seconds north; 80 degrees 15 minutes 04 seconds west.
