资源简介：
The Mark Twain site (48SW13992) exhibits evidence of at least three occupation
components. The oldest component includes three hearths, two of which were excavated into the
regolith immediately above bedrock. Feature 3 yielded a radiocarbon age of 4410 ± 50 B.P. (2
Sigma 5280-5170 B.P., 5130 - 5100 B.P., and 5080 - 4860 B.P.). Features 3 and 4, both from this
occupation, were sampled for pollen (Table 1). The middle occupation is represented by Feature
5, a basin-shaped hearth, that yielded a radiocarbon age of 2040 ±. 50 B.P. (2 Sigma 2140 -1860
B.P.). Feature 1, a basin-shaped hearth, and a metate represent the upper components. Feature
1 yielded a radiocarbon age of 1260 ± 60 B.P. (2 Sigma 1290-1060 B.P.). Pollen analysis was
undertaken on four hearths representing three occupation components and a metate wash,
representing the upper most occupation to identify any plants that might have been processed in
or near these hearths or using this metate.
