Twenty-three specimens are classified as side scrapers. In general, as with discoidal scrapers, it is hard to draw a line between these and utilized flakes. An arbitrary division was made because, when the material was laid out, some specimens consistently showed more regular work or flaking than others. The largest of these is 2½ × 1 inch, the smallest 1¼ × 1 inch. In general, they are long flakes with considerable flat flaking and/or retouch along one face, usually on only one edge. Quartzite and crypto-crystalline quartz were about equally popular.
Discoidal Scrapers ([Fig. 35])
Twenty-five artifacts are classified as discoidal scrapers. Again, as noted in the case of side scrapers, the dividing line between some of these and certain utilized flakes is somewhat arbitrary. Generally these artifacts are steeply flaked, by percussion, on both faces and all edges, giving them a rather rounded appearance. The largest is 2½ × 2¼ inches, the smallest ¾ × 1½ inch. Quartzite and flinty materials show about equal usage.
Serrated Scrapers ([Fig. 37])
There are 21 serrated scrapers. These are usually serrated on one edge only, but other sides often show secondary usage. The serrations appear to have been made in the course of the primary flaking, by blows dealt at intervals, with the remaining protrusions left instead of being chipped off. Some with steep sides would have been useful as scrapers, but several small thin specimens could have been used as saws. Flinty materials were preferred. The largest is 2 × 1¼, the smallest 1 × ¾ inches. From the ethnographic data ([see below]) it is interesting to note that the Ute used serrated scrapers for taking the hair off hides.
“Uncompahgre” Scrapers ([Fig. 36])
Six complete and one broken artifact are included in this category. They conform in general to Wormington and Lister’s (1956) description of those found at the type locality. Those at LoDaisKa are smaller. Specifically they are flakes, usually triangular, although one is rectangular. One edge is flaked on one face alone, one or more edges are flaked on both faces. The butt, generally the striking platform of the flake, is usually unflaked and thick. They appear to have been serviceable without hafting, and are probably a multiple purpose tool, possibly with a specific combination of uses. The largest is 2 × 1¾ inches; the smallest, 1¼ × ⅞ inches. All but one are quartzite.
Hafted Scrapers
One artifact was found that could be described as a hafted scraper. It is 1 × 1¼ inches, with a semicircular working bit, straight barbs, expanding stem, narrower than a blade, and a rounded base. It could have been made from a type H projectile point.
