Class III Inventory, Colowyo's Collom Mine Project 91 <br />• <br />6.1.19 Site 5MF6077 (NF -22) <br />Site Tyne Prehistoric lithic scatter <br />Legal Locatio Section 13, T4N, R94W <br />Landowner Private <br />Site Dimensio 77 x 66 m <br />Site Description Site 5MF6077 is a prehistoric lithic scatter located at 6,640 ft (2,024 m) on the <br />southeast - facing slope of a northeast - trending ridge (Figure 6.40). The site is on the west side of <br />Collom Gulch and southwest of the mouth of the gulch and the confluence of Collom and Little <br />Collom Gulches. Axial Basin is located to the north. The general area has numerous <br />northeast- trending ridges and gulches, as well as exposures of bedrock and coal seams (Figure 6.41). <br />On -site sediment consists of shallow intermixed aeolian silty sand and colluvium with gravel and <br />( eroding bedrock detritus. The vegetation community consists of sagebrush, rabbitbrush, cheatgrass, <br />various low grasses, and various forbs. Impacts to the site include extensive slopewash, <br />downcutting, and livestock grazing. <br />• <br />The lithic scatter consists of one projectile point, three bifaces, one flake tool, one multidirectional <br />core, 22 flakes, and one groundstone tool. The projectile point is a small corner - notched specimen <br />missing the distal portion and the stem (Figure 6.42). The extant portion measures 20P x 14 x 4 mm <br />and is made of fossiliferous chest. The blade is triangular in plan view and biconvex in cross section <br />and exhibits random flaking. The shoulders are sharp to somewhat downswept. One of the bifaces <br />is a complete blank made of fossiliferous chert that measures 4.1 x 2.4 x 1.6 cm. The absence of <br />usewear suggests that the blank is a manufacturing stage. The other two bifaces are indeterminate <br />bifaces. One is a medial /lateral portion that measures 2AP x 2.3P x 0.6 cm that is made of opaque <br />chert. It appears to have a large unrefined notch but is too incomplete for accurate analysis. The <br />second indeterminate biface is a distal tip from an early stage biface made of semitranslucent chert. <br />The artifact measures 2.51? x 2AP x 0.4 cm. The flake tool is a retouched and utilized complete <br />quartzite tertiary flake that measures 2.6 x 2.6 x 0.4 cm. The dorsal surface has been retouched to <br />47599 TRC Mariah Associates Inc. <br />■ <br />
