Basic information
Sample name: Charlie Lake Cave (Zone IV)
Sample aka: HbRf 39

Reference: J. C. Driver. 1988. Late Pleistocene and Holocene vertebrates and palaeoenvironments from Charlie Lake Cave, northeast British Columbia. Canadian Journal of Earth Sciences 25:1545-1553 [ER 3152]
Country: Canada
State: British Columbia

Coordinate: 56° 16' 35" N, 120° 56' 15" W
Basis of coordinate: stated in text
Geography comments: "a small cave and an external filled gully... on the north side of Stoddart Creek, which drains Charlie Lake, northwest of Fort St. John"
there are three accepted radiocarbon dates on Zone IV ranging from 4270 +/- 160 to 1400 +/- 400 BP, plus an older date out of stratigraphic position
Climate and habitat
Lithology: sandstone
Habitat comments: "the gully contains at least 4 m of fine sediments and sandstone fragments from which artifacts and fauna have been recovered" so this is not a cave fauna per se
Zone IV "is a relatively homogeneous, thick, highly organic sediment. Granulometric characteristics are similar to those of IIb" and II is dominated by sands, so this is presumably a sandstone
"The general paucity of artifacts argues for very brief periods of human use" so "most of the fauna was not deposited as a result of human use" and the assemblage includes species that "certainly lived and died at the site", were "deposited as dismembered prey items", and "were deposited in owl pellets"
no details are given about the artifacts and Fladmark et al. (1988) detail a small lithic assemblage entirely from Zone IIa, so it is possible that none are present in this zone
