[Herbert C. Kraft et al. (1994)] From 30 to 40 cm came uncarbonized bark and oak (Gary Crites, personal communication 1993). Surprising was the absence of American Beech. Wood Charcoal Charcoal was rare in the portion of the site most recently excavated and was usually scattered in the upper levels, suggesting an Historic Period burn. Unfortunately, most of the charcoal pieces were too small, too mineralized, or too few for identification even to the family level. Herein may lie an explanation for the Table 5. Dogan Point Radiocarbon Ages (Little 1994) 34 Spring 1994 No. 107 Radiocarbon Dates difference in collagen content is slight, but the results show that our archaeological bone had lost 80 percent of its collagen [Brennan 1981:50). Twenty-one radiocarbon dates have been run on Dogan Point samples (Figure 5, Table 5). Seventeen dates were derived from single oyster valves, three were from charcoal, and one came from antler collagen. Charcoal Collagen Although there were at least six hearths and one firereddened area identified by Brennan and one from Square 1 Levels 8-9 in the most recent work, charcoal of sufficient quantity for dating by conventional means was rarely encountered. Charcoal not associated with hearths was abundant in the upper 20 cm of squares excavated in the northwestern portion of the site. Coal was also found in these levels. In three cases charcoal was submitted for dating with raw dates ranging from 735 ± 30 rcy to 310 ± 65 rcy. Only the 735 ± 30 date is potentially acceptable.
