河北阳原泥河湾盆地的籍箕滩旧石器时代晚期旷野遗址群于上世纪80年代被发现并系统发掘,目前,曾出土了丰富的细石叶制品及动物碎骨的第2地点（T2）由于后期工程建设的原因已不复存在,原记录中的第1地点（T1）、第3地点（T3）也均受到了不同程度的人为破坏或自然力侵蚀。为探明遗址堆积保存状况,工作队对遗址第1、3地点进行了复查及剖面清理,分别发现了密度较大的石制品遗存。对第1地点和第3地点的光释光和¹⁴C测年结果表明,该地有人类活动遗迹的堆积物形成年代为距今16000余年至全新世初期,与河对岸虎头梁遗址群中的马鞍山、于家沟相当,表明了当时古人类的活动范围同时覆盖了桑干河南北两岸。

Jijitan site, which is located in Nihewan Basin, Heibei Province in northern China, was discovered in the 1980s. Three localities were documented, among which Locality 2 (T2) yielded the most specimens, including lithic artifacts and animal bones. Due to modern dam construction, Locality 2 was totally destroyed and no archaeological deposits preserved. Localities 1 and 3 are partly preserved, although badly destroyed by natural agencies and modern human activities. In our project, Localities 1 and 3 are re-examined, and a high density of lithic artifacts unearthed. OSL and Radiocarbon dating indicate that the anthropogenic deposits of Localities 1 and 3 were accumulated from about 16000 years ago to the early Holocene, which overlaps with the Hutouliang site complex on the opposite side of the Sanggan River. This result indicates that, during this time period, ancient humans occupied a vast area along the Sanggan River, and the population was fairly large.
