The end scrapers are divisible into three categories. The first form is
a flat scraper, generally triangular to oval in outline. The working
end is often thin. There are a few true snub-nosed scrapers in this
category. The second type is generally fan-shaped with a wide thin bit.
The opposite end usually tapers to a sharp edge which could have had
secondary use as a cutting tool. The third variety includes rougher
forms, though there are a few well made specimens. All have a distinct
keel. There are 31 of the first type, the smallest ½ × ⁷/₁₆; the
largest 1¼ × 1½ inches. Of the second group there are 17 specimens, the
smallest 1¼ × ¾; the largest 1½ × 1¼ inches. There are 10 of the third
form, the smallest 1 inch square, the largest 2½ × 1½ inches. Seventy
percent of the scrapers are of crypto-crystalline quartz.
