Site 8, has been identified by Van Den Berg as a quarry site. Site 8 is known locally as Huay Luang and comprises five areas where partially completed jars are located on the slopes of the mountain.
The area exhibits evidence of heavy bombardment from the war in Laos with numerous craters apparent among the partially completed jars and rock faces which bear chisel scarring. Preliminary identification of the rock suggests that this mountain is the source of both the Site 2 and Site 3 jars.
In 2023 Plain of Jars Archaeological Research Project members visited Site 8 and deployed a UAV LiDAR to map the quarry. Results of this mission are pending.
