Basic information
Sample name: Smith Creek Canyon (Reddish-brown Silt)
Reference: J. I. Mead, R. S. Thompson, and T. R. Van Devender. 1982. Late Wisconsinan and Holocene fauna from Smith Creek Canyon, Snake Range, Nevada. Transactions of the San Diego Society of Natural History 20(1):1-26 [ER 3216]
Geography
Country: United States
State: Nevada
Coordinate: 39.34° N, -114.16° W
Coordinate basis: based on nearby landmark
Time interval: Late Pleistocene
Ma: 0.02865
Age basis: radiocarbon (uncalibrated)
Geography comments: "opens into the Lake Bonneville playa in the Snake Valley" (coordinate based on North Fork Smith Creek)
Bryan (1979) reported "a collagen date of 28,650 +/- 760 years B.P." but Velastro (1977) claimed it was on charcoal, which is absent in the layer; the current authors believe it to have been on "bone scraps" (presumed to be uncalibrated because the error is symmetrically distributed)

Environment
Lithology: siltstone
Taphonomic context: aeolian deposit,bird accumulation,cave
Habitat comments: "of probable eolian deposition, although it is just as likely that water from a nearby ceiling conduit may have caused the erosion of the first stratigraphic unit and at least a partial deposition of the Reddish-brown Silt. This unit" is "partially a raptor accumulation"
Methods
Life forms: bats,carnivores,rodents,ungulates,other small mammals,lizards,snakes,frogs,fishes
Sampling methods: quarry
Sample size: 273 specimens
Sampled by: A. L. Bryan
