Context
basin-shaped hearth, 7 m north of the hearth dated by I-5449, in the same stratigraphic position. Hearth 4A, one of 4 dates from this hearth. This plus one other are statistically contemporaneously at ca. 7955 +/- 55 BP. Not clear why one date is over 1000 years older. A much younger date is probably the result of krotovina. The 2 contemporaneous dates are the most acceptable. The hearth stain, very reddish black, occurred at the top of Stratum 3, the same stratigraphic position as Hearth A-1 excavated by Benedict (1985). Densely packed with charcoal, 3 flakes. Two of these match description of material identified in Benedict's Workshop A
