The area know as the rockpile was located where in Vietnam?

Answer 1

MR-I (Military Region I, also known as I Corps). Drive due west along Hwy 9 (also called Route 9 or QL 9) starting from Dong Ha/Quang Tri (Dong Ha & QT are next to each other). It'll be a dirt road after a few miles from Quang Tri; nearing the old Khe Sanh Firebase area the Rock-pile will be on the right, about a mile north of RT 9. Looks like a lone mountain peak and not a pile of rocks. All open area around it between the highway and the mountain. Attached to the Rockpile northward (behind it) are a chain of hills (mountains) that was called the "Razor-backs" by GI's. In the open area from the base of the mountain to highway 9, two or three miles west exactly on the south edge of the highway stood Firebase Vandergrift. Vandergrift took alot of rockets (122mm) from the Rock-Pile area...you could hear them coming.

Answer 2

The rockpile, also known as Thon Khe Tri, was located in the Demilitarized Zone (DMZ) of Vietnam, near the border with Laos. It was a rocky outcrop that provided a strategic vantage point for observing and controlling the surrounding area. The rockpile was heavily contested during the Vietnam War.
