Mason-Dixon Line Western Crossings

"Extending the Line" page

Welcome to the West Virginia Panhandle!

If the Mason-Dixon Line was extended to the Ohio River, it would run along the border of Marshall and Wetzel counties in West Virginia. Though no Mason and Dixon-related surveying was done beyond Pennsylvania's southwest corner, there are some who still call this the "Mason-Dixon Line" because of the Missouri Compromise of 1820 which refers to a division between free and slave states.

So late in 2006, Colleen Nelson and I undertook an expedition to the place where this line meets the Ohio River.

Thanks to Tom James for being our terrific guide!
