Haystack Cave (upper levels)
Basic information
Sample name: Haystack Cave (upper levels)
Sample aka: 5GN 189

Country: United States
State: Colorado

Coordinate: 38.48° N, -107.17° W
Basis of coordinate: stated in text
Geography comments: NE1/4, SE1/4 of sec. 27, T49N, R3W"
there are "Two carbon 14 dates... based on bone apatite of unidentifiable fragments from levels 3 and 4 and 5 and 6", the first being 14, 935 +/- 610 B.P. and the second being "less accurate due to lesser amounts of available bone" and 12, 154 +/- 1, 700 B.P.
upper levels (1 to 3) are "disturbed" and possibly Holocene because no extinct fauna are present
Climate and habitat
Lithology: not described
Taphonomic context: bird accumulation, cave
Habitat comments: "a small volcanic lava tube"
"cultural remains are distinct only in the upper two levels (40 cm)... deposition of bone in the lower levels probably is due to natural rather than cultural processes... bone deposition probably resulted from carnivores using the cave as a den, rodents (especially woodrats) dragging bones into the cave and nesting there, and birds roosting there... carnivores... may have been the primary source of bone deposition"
Life forms: carnivores, rodents, ungulates, other small mammals, birds, lizards
Sampling methods: quarry, screenwash
Sample size: 156
Sampling comments: "All matrix was screened through one-quarter-inch screen"
Sample: 3403
