The Rockpile



The Rockpile (MGRS XD979559), known in Vietnamese as Thon Khe Tri, is a karst rock outcropping near the former South Vietnamese DMZ. It rises to an elevation of 240 m MSL, about 210 m above the surrounding terrain. Its relatively inaccessible location, reached only by helicopter, made it an important United States Army and Marine Corps observation post and artillery base from 1966 to 1968.
