[Various (1967)] At Pickle Hill, 65% of all artifacts were whole, fragmentary, or unfinished projectile points. Scrapers, such as those found at Pickle Hill, are usually assumed to have been used in working hides, but a more likely function in view of their small size may have been woodworking (Ritchie, personal communication). Gouges and other ground stone implements may have served to chop trees, cut poles for houses, or carve dugout canoes. As previously suggested, the anvilhammerstone may have functioned partly as a rest for chipping proje ctile points. Hammerstones were probably multi-purpose tools. Whetstones could have been employed in shaping ground stone woodworking tools, but their function in the culture remains problematical, as is the case with so many artifacts from archeological contexts. Radiocarbon dates from the Bent site have placed the River component there at about 1350 B. C. and 1930 B.C. (Ritchie 1965: 126). The younger date is regarded as less acceptable. This interpretation receives considerable support from a date of 1760 B.C. ± PLATE 2. PICKLE HILL SITE ARTIFACTS.
