Class III Inventory, Colowyo's Collom Mine Project 87 <br />• <br />Landowner Private <br />Site Dimensions 440 x 200 m <br />Site Descripti Site 5MF6076 is a prehistoric open camp located on a ridge spur at the north end <br />of a northeast - trending ridgeline (Figure 6.37). The site lies at 6,680 ft (2,036 m) and overlooks the <br />mouth of Morgan Gulch to the west and Axial Basin to the north. On -site sediment consists of <br />shallow sheet deposits overlying and intermixed with eroding sandstone gravel and bedrock detritus. <br />Exposures of bedrock occur throughout the ridge spur in general and within the site proper <br />(Figure 6.3 8). 'The vegetation community consists of sagebrush, rabbitbrush, cheatgrass, low grasses, <br />and various forbs. Impacts to the site include vehicular traffic along a two -track road that passes <br />through the site along the crest of the ridge spur, erosion, and livestock trampling. <br />The open carne consists of one eroded hearth (Feature 1) and a scatter of flaked stone artifacts. <br />Feature 1 consists of the very poorly preserved remains of a hearth located in the two - track road at <br />the north end of the site. The feature consists of charcoal - stained sediment that measures 63 x <br />43 em. An unspecified number of heat - altered rock fragments were noted in and around the staining. <br />The feature has been heavily impacted by vehicle traffic and cattle grazing. <br />The flaked stone artifact assemblage consists of one projectile point, two bifaces, two flake tools, <br />and 207 flakes. The projectile point is a nearly complete stemmed specimen that compares favorably <br />with McKean stemmed types (Figure 6.39). It measures 34 x 21 x 5 mm and is missing one corner <br />of the hafting element. The randomly flaked blade is triangular in plan view with slightly expanding <br />margins and is biconvex in cross section. The straight stem is 11 mm in length and 14 mm wide. <br />The extant portion of the base appears flat. The specimen is made of mottled opaque chert. The two <br />bifaces appear to be manufacturing stages. One is made of gray opaque chert. It is finely flaked and <br />measures 1.9 x 1.3 x 0.3 cm. The second biface is a preblank made of white opaque chert that <br />measures 3.2 x 1.7 x 0.6 cm. <br />• <br />47599 TRC Mariah Associates Inc. <br />
