ends. Surface sediment is brown loam with some small gravels present and probably consists of a <br />mix of aeolian deposition, residuum and slopewashed sediments. <br />P1 P2 <br />2 cm <br />Figure 3. 5RT2699 projectile points. <br />tertiary flakes. <br />Artifacts at site 5RT2699, which <br />measures 34 in N/S x 11 in E/W, include one <br />complete projectile point (P 1), one projectile <br />point base (P2) and three flakes. Both <br />projectile points (Figure 3) are white chert. <br />The complete point has an expanding base <br />with deep corner-notching and a serrated <br />blade. The point type likely dates to the <br />Late Plains Archaic. The projectile point <br />base is an indented, stemmed variety similar <br />to McKean types of the Middle Plains <br />Archaic. The flakes are white chert, dark <br />brown chert and gray quartzite. All three are <br />Eligibility and Management Recommendations. This site may retain integrity. While <br />only five artifacts were noted on the surface, they consist of two projectile points and three flakes <br />of different material types; the projectile points appear to be associated with two different time <br />periods. The five artifacts which make up the site are contained within a small area in a cultivated <br />field and are likely somewhat out of context due to farming activities. However, ground visibility <br />was excellent in the vicinity with no nearby evidence of other cultural material spread across the <br />field; these artifacts appear to be discrete. It is possible that cultivation reached deeper in this <br />specific location than in other parts of the field and disturbed a cultural level buried beneath the <br />plow zone. If this is true, a cultural level may remain largely intact, disturbed only at the location <br />of these few artifacts, making it possible that the site retains integrity. Deposition of unknown depth <br />appears to be present; no cobbles or evidence of residual sediments were observed in the field. <br />Because it is possible that the site may retain integrity and may preserve a continuous, buried and <br />datable cultural level beneath the plow zone, MAC recommends this site as needs data. If the site <br />will be subjected to physical, disturbance from mine facilities, testing and/or data recovery should <br />occur. Assessment of potential effects from subsidence will be evaluated as part of a recommended <br />site condition monitoring program for the mine. Testing or data recovery may be triggered under <br />this program if the potential for site degradation from subsidence is observed during the monitoring <br />program. <br />5RT2731 (MM7275) <br />Site Description. This newly recorded, prehistoric lithic scatter is located about four miles <br />south of the Yampa River in a narrow valley. The site is situated near the base of a small hill on a <br />slight northeast-facing slope. The steeper slopes of Hillberry Mountain are about 1.5 miles to the <br />southwest. The site, measuring approximately 66 in N/S x 66 m E/W, sits in a broad, shallow <br />drainage basin and is generally bounded on the north by an arroyo with flows east/northeast to its <br />confluence with Grassy Creek. In addition, two shallow drainages flow northeast through the site <br />near its western and eastern edges. All of these subsurface exposures were carefully inspected for <br />evidence of a buried cultural' level or buried cultural materials. The surrounding area is vegetated <br />29
