Class Iff Inventory, Colowyo's Collom Mine Project 121 <br />s <br />4 <br />Landowne Private <br />Site Dimensio 113 x 50 m <br />Site Description Site 5MF6086 is a large and diffuse open camp located on the lower slope of the <br />north end of a northeast- trending ridge between the mouths of Morgan and Collom Gulches <br />(Figure 6.62). It lies at an elevation of 6,600 ft (2,012 in), and the end of the ridge overlooks a broad <br />drainage basin to the north (Figure 6.63). Surface sediment consists of fine- grained silty sand with <br />eroding sandstone gravel and cobbles. The vegetation community consists of scattered sagebrush, <br />rabbitbrush, cheatgrass, low grasses, various forbs, some prickly pear cactus, and one juniper. The <br />site has been impacted by slopewash and grazing. <br />The artifact assemblage consists of one multidirectional core, 29 flakes, and one metate fragment. <br />The core is made of banded chert, exhibits 17 flake scars, and measures 4.5 x 3.4 x 1.8 cm. The <br />debitage assemblage is dominated by 27 tertiary flakes. The remainder consists of one primary flake <br />and one secondary flake. White opaque chert is the most common material type with 16 flakes, of <br />which 14 flakes are tertiary, with one primary flake and one secondary flake. The remainder of the <br />assemblage consists of five opaque chert tertiary flakes, five quartzite tertiary flakes and three <br />banded chert tertiary flakes. The metate fragment is made of sandstone and measures 8.4P x 5.OP x <br />2.9 cm. The fragment is a portion of a unifacially ground metate face with light pecking on the <br />ground surface (Figure 6.64). <br />Testing Results Two shovel tests were excavated at the site in locations that appeared to have <br />potential for sediment depth. Shovel Test 1 was placed above the terrace edge in the eastern part of <br />the site. Shovel Test 2 was placed in an upslope location in the western part of the site and in <br />relative proximity to a fenceline that bounds the site. Sediment encountered in both shovel tests <br />consisted of consolidated sandy silt to a depth of 35 cm below ground surface. Underlying this strata <br />was consolidated clay residuum. No subsurface cultural deposits were identified in the shovel tests. <br />47599 <br />TRC Mariah Associates Inc. <br />
