Blasterz have puzzled over this one, but reading the NGS Datasheets it is clear that they are referring to the SAME DRESSED STONE MONUMENT that was set in 1849 next to an original 1765 Mason-Dixon stone.
Whatever. We will simply waymark this as JU3840 and call it good.
The two historic stone monuments are nestled together inside a tall wrought-iron fence in a creepy overgrown brambley area in back of an apartment complex in Elkton MD.
