2023 Cultural Resource Site Assessments for Collom Expansion Project Colowyo <br />Tetra Tech June 2023 10 <br />For Official Use Only: Disclosure of Site Locations Prohibited (43 CFR 7.18) <br /> <br />Figure 5. Site 5MF.1652 overview, facing north. Taken by E. Shikrallah on 5/16/2023. <br />5MF.3996 – Prehistoric Camp Site, Needs Data <br />Site 5MF.3996 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 recorders reported the site as containing three areas of burned bone and charcoal <br />which were eroding out of the eastern and western cutbanks of the West Fork of Jubb Creek. The <br />site has been revisited since the original recording. It was revisited in 2005 by TRC as part of the <br />Collom Mine Expansion Class III Inventory project and in 2015 by Tetra Tech as part of the Collom <br />Mine Expansion Site Assessment project. The datum was not relocated during either revisit; <br />however, TRC discovered eight large mammal bones in addition to light staining and a single <br />piece of charcoal. <br />In 2015, Tetra Tech revisited the site as part of the Collom Mine Expansion Site Assessment <br />project. During the revisit, none of the previously reported charcoal, stained sediments, or charred <br />or uncharred bone were observed at the site. The site had been overgrown and the road had <br />been unused in recent years with significant vegetation growth within its grade. One vertebra and <br />one ilium of a medium sized ungulate, likely a deer, were found in the southern end of the site. <br />The bones were unmodified, and likely due to a natural death and not associated with any <br />potential cultural manifestation. No staining was identified, and it was still undetermined whether <br />the site was cultural or natural in origin. The eastern cutbank appeared to have been heavily <br />impacted by cattle grazing activities evidenced by hoof prints, trampled vegetation and manure <br />piles. No evidence was observed that the cattle grazing impacts had adversely affected any <br />reported cultural manifestations. Overall, site integrity remained fair. <br />In 2019, Tetra Tech revisited the site as part of the second round of assessments. The site <br />condition had not changed since the 2015 revisit. The site had not been adversely affected by
