Comments
FdOt-1, Anderson: This site was discovered in a gas pipeline right-of-way. Tests A and B yielded materials attributable to Old Women's, Avonlea, Besant, Pelican Lake, Hanna, and Mummy Cave occupations that may well span the last half of the Holocene. Quigg (1984: 152) notes that "the cultural material appeared to be vertically dispersed throughout the profiles of each unit with the exception of one well-defined occupation floor in Test B." Four dates, consisting of gelatin and apatite fractions of two samples of bone, are assigned to this well defined occupation which is attributed to the Mummy Cave complex. Quigg (1984: 156) comments on the dates: "One can see that the two apatite dates are only 25 radiocarbon years apart, while the gelatin dates are 735 radiocarbon years apart. ... Suffice to say that the four dates come to an average age of 2775 B.C. Although there appeared to be some weathering of the faunal remains in this Bitterroot occupation, I see no substantial reason to reject this age for this particular occupation." The cultural affiliations of GX-6128, GX-6131, and S-1894 have not been reported.
