1994年4月,贵州仁怀县云仙洞风景区筹建组在县城东门河开发云仙洞的施工中,发现一石灰岩溶洞内的地层断面上有陶器、石器等包含物,立即报告县文管所及省文物考古研究所。经调查确认,这里为一处洞穴遗址。随后,省、县文物部门联合进行了抢救性清理。 In April 1994, the construction team of Yunxian Cave Scenic Area in Renhuai County, Guizhou Province, developed the construction of Yunxian Cave at the Dongmen River in the county and found that there were pottery, stoneware and other inclusions in the stratigraphic section in a limestone cave and immediately reported to the county administrative office And Provincial Institute of Cultural Relics and Archeology. After investigation confirmed that here is a cave site. Subsequently, the provincial and county cultural relics jointly conducted a salvage clean-up.
