2023 Cultural Resource Site Assessments for Collom Expansion Project Colowyo <br />Tetra Tech June 2023 12 <br />For Official Use Only: Disclosure of Site Locations Prohibited (43 CFR 7.18) <br /> <br />Figure 7. Site 5MF.3996, slump overview, facing southeast. Taken by E. Shikrallah on <br />5/17/2023. <br />5MF.4003 – Historic Homestead and Prehistoric Lithic Scatter, Needs Data <br />Site 5MF.4003 was originally recorded in 1995 by Metcalf Archaeological Consultants for the <br />Colowyo Coal Company Lease and Exploration Areas: Class III Cultural Resource Inventory <br />project. The site includes a historic homestead and an open prehistoric camp situated along the <br />banks of Wilson Creek. The prehistoric cultural material reported included 100+ white chert <br />tertiary flakes, numerous HAR fragments, three manos, one quartzite flake, three obsidian flakes, <br />a chert endscraper, and a utilized flake. The historic portion of the site consists of three buildings, <br />an underground storage structure, a corral, and a surface trash scatter. Building 1 is a log <br />outhouse, Buildings 2 and 3 are both log structures, and Building 4 is a stone dugout with uncut <br />stone walls and an earthen roof. The artifact scatter primarily consists of building materials such <br />as logs, lumber, brick, cement, corrugated metal, and asphalt/tar paper in addition to <br />miscellaneous trash including utensils, stove parts, nuts, bolts, buckets, wagon/car parts, buttons, <br />fabric, leather, and barrels. The site has been revisited twice since the original recording. It was <br />revisited in 2005 by TRC as part of the Collom Mine Expansion Class III Inventory project and in <br />2015 by Tetra Tech as part of the Collom Mine Expansion Site Assessment project. In 2005, TRC <br />noted that the prehistoric component appeared to be in a similar condition as when it was recorded <br />in 1995. New material identified included approximately 15 opaque white chert flakes, <br />approximately ten pieces of HAR, and two manos. They stated that the historic component <br />seemed unchanged at the time of survey. <br />In 2015, Tetra Tech revisited the site as part of the Collom Mine Expansion Site Assessment <br />project. The historic component was found to be in worse condition than when it was previously <br />recorded in 2005. Buildings 1 and 2 had been demolished into a single pile by an unknown <br />disturbance during an unknown activity. A large area of vegetation removal appeared to have
