Basic information
Sample name: North Creek Shelter (Paleoarchaic)

Reference: J. C. Janetski, M. L. Bodily, B. A. Newbold, and D. T. Yoder. 2012. The Paleoarchaic to Early Archaic transition on the Colorado Plateau: the archaeology of North Creek Shelter. American Antiquity 77(1):125-159 [ER 3138]
Country: United States
State: Utah

Coordinate: 37° 46' N, 111° 36' W
Basis of coordinate: based on nearby landmark
Geography comments: "on the west edge of Escalante Valley... at the base of a south-to-southwest facing sandstone cliff" close to the origin of the Escalante River (coordinate based on Escalante)
Paleoarchaic levels are IIg, IIIb, and IIIe, whereas Early Archaic levels are Va and Vt
there are two conventional dates on IIa of 9960 +/- 30 and 9800 +/- 50 ybp, one on IIIa of 9690 +/- 60 ybp, and one on IVa of 9510 +/- 80 ybp, so the latter two bracket the Paleoarchaic fauna
Climate and habitat
