Geography comments: "The Yujiagou site is located in a small valley about 500 m northeast of Hutouliang Ridge, within the Nihewan Basin, an intermontane depression surrounded by the Xiong'er Mountains in the north and an extension of the Heng Mountains in the south, covering an area of roughly 1849 km2".
"Eight bone samples from layers 2–5 were radiocarbon dated. These dates could be divided into two ranges: layers 2 and 3a date from c. 10, 373 to 8406 cal. BP, and layers 3b, 4 and 5 date from ca. 16, 023 to 13, 855 cal. BP.

Environment
Lithology: siltstone

Taphonomic context: human accumulation

Archaeology: bone tools, ceramics, stone tools, other artifacts

Habitat comments: "Fieldwork conducted at Yujiagou revealed a stratigraphic section with a total depth of approximately 8 m, comprising seven archaeological layers numbered 1 to 7 from top to bottom".
"The sequence consists mainly of loess silt in layers 1–4; Layer 4 comprises a dense brown-gray loess silt with rust-like sediments".
"Numerous lithic artifacts, bone and antler tools, ceramics, and ornaments were recovered during the excavations. The lithic assemblage is indicative of a micro-blade industry characterized by the presence of wedged-shaped micro-blade cores".
"Humans were the primary agents of the accumulation and modification of the bone assemblages; non-human biotic agents had a low impact on the formational history of the faunal assemblages from Yujiagou".

Methods
Life forms: ungulates, birds

Sampling methods: quarry, screenwash

Sample size: 81 specimens

Years: 1995 - 1997

Net or trap nights: 0

Basal area status: not applicable

Sampling comments: "From 1995 to 1997, the Hebei Province Cultural Relics Bureau and Peking University conducted systematic excavations over a 120 m2 area. The investigators employed a meter-square grid and dug in 5 cm spits to maintain provenience control. Sediments were dry- and wet-screened to retrieve microfauna and smaller artifacts".
