Class III Inventory, Colowyo's Collom Mine Project 231 <br />• <br />6.1.58 Site 5MF6116 (RR -6) <br />Site Tyne Cairn <br />Legal Location Section 23, T4N, R94W <br />Landowner Private <br />Site Dimensions 2 x 1 m <br />Site Description Site 5MF6116 is a collapsed cairn of unknown origin located on a low <br />northwest - facing hill on the west side of a major northeast- trending ridge east of Morgan Gulch <br />(Figure 6.139). The low hill has an elevation of 6,911 ft (2,106 m), and the cairn is in a midslope <br />position between the crest of the ridge to the east and Morgan Gulch to the west (Figure 6.140). <br />Exposures of sandstone bedrock are common throughout the area. On -site sediment consists of <br />residual sandy clay and bedrock. The vegetation community consists of scattered sagebrush, <br />rabbitbrush, sparse low bunchgrasses, and few forbs. Impacts to the site include erosion, livestock <br />(� trampling, and neglect. <br />The cairn (Feature 1) consists of approximately 50 unshaped tabular sandstone slabs readily available <br />in the immediate area (Figure 6.141). It has collapsed uphill and covers an area roughly 1 x 2 m in <br />size. The cairn bad an estimated original height of 4 ft (1 m). The basal remnants still in place are <br />not well sodded in, which suggests that it does not have great time depth and may be historic in age. <br />Although its location does not coincide with section lines or corners, the cairn appears similar to <br />other historic cairns in the project area that do reflect land locations. These considerations form the <br />basis for recording the cairn as a historic construct, although this assessment is conjecture. No <br />artifacts were recorded in association with the cairn. <br />• <br />The site was not tested owing to the nature of the site and its location on residual sediment and <br />bedrock. <br />47599 TRC Mariah Associates Inc. <br />
