Introduction 5RT132 is a relatively large chipped and ground stone scatter covering an area of about 25,000 m at an elevation of 2268 m {7440 ft) in low mountainous terrain south of Hayden, Colorado (Figure 1). The site was originally recorded by personnel from Western Cultural Resource Management (WCRM) during a 1979 survey for Peabody Coal Company's Seneca II-W mine expansion. Testing for National Register eligibility was recommended by WCRM. Mapping and non- collecting surface analysis occurred during survey. Testing of the site occurred on August 17 and 18, 1989. Metcalf Archaeological Consultants, Inc. (MAC) was contracted by Peabody Coal Company (Peabody) to test the site for basic National Register of Historic Places eligibility and, if appropriate, to design a data recovery or mitigation plan. This testing showed that surface artifacts are relatively abundant, but that intact remains are limited to a very small area. The site is evaluated as not eligible for the National Register of Historic Places {NRHP). The site is on private surface with Bureau of Land Management-managed minerals beneath. For cultural resources review, the BLM, Office of Surface Mining (OSM) and State Historic Preservation Office (SHPO) are involved. Because of land ownership, no federal antiquities permits apply. A work plan was discussed with BLM Little Snake Resource Area archaeologist Brian Naze and OSM archaeologist Foster Kirby prior to fieldwork,__ __ _ _ _ Environment The general environment of the study area surroundings has been described in detail by LaPoint (1987) and only a summary is needed here. 5RT132 is located in the northern foothills of the Williams Fork Mountains toward the northern end of the Southern Rocky Mountains (Thornbury 1965)• The area is drained by the Yampa River, a major tributary of the Green River. 5RT132 is situated along both flanks of an unnamed tributary of Dry Creek, a stream which joins the Yampa at the town of Hayden, Colorado. Local geology is dominated by two formations, the Pierre shale and the coal-bearing Iles Formation. The site lies on• the Pierre shale, and its thin mantle of surface soil derives from this parent material. Thus the soil is quite clayey, and is quite variable in the degree of soil development and in the thickness of preserved Holocene soil. The site lies within the Mountain Shrub vegetation zone with aspen grove, serviceberry and scrub oak all present within the site boundaries. Understory cover is quite variable and includes grasses, sagebrush and various forbs in addition to large patches of barren ground. The site surface could be characterized as highly disturbed. Disturbing agents include deep channel incision and extensive hill slope erosion, historic stock pond construction, game end stock trails and burrowing. No mining-related impacts ere evident.
