Introduction Metcalf Archaeological Consultants. Inc. (MAC) conducted a Class III cultural resource inventory for proposed seismic line 95B, eight drill hole sites, and access improvements. This inventory was completed for Cyprus Empire Corporation. Craig, Colorado. Surface ownership is predominantly private, but because the proposed project will develop federal minerals administered by the Bureau of Land Management (BLM), the project is considered a federal undertaking. In accordance with policies and regulations implementing the National Historic Preservation Act (Public Law 89-665), as amended, the cultural resource inventory was completed to locate, identify and evaluate any cultural resources that might be affected by the proposed undertaking. The inventory was completed by MAC archaeologist Carl Spath, Ph.D. on July 17 and 18 under the stipulations of BLM Antiquities Permit #039290, which expires on 22 September 1995. All field documentation, original records. and copies of this report are on file at the MAC office in Eagle. Colorado. The proposed project consists of approximately 13,500 feet of 300 foot wide seismic corridor, eight exploratory drill hole sites, and approximately 8400 feet of previously uninventoried access improvements. A 150 foot radius was surveyed around each staked drill location, for a survey area of approximately 1.6 acres. A 100 foot wide corridor was surveyed for proposed access improvements. The project area is located in T 6 N, R 91 W, Sections 18 and 19, and in T 6 N, R 92 W, Sections 12-14 and 23-24, Moffat County, Colorado (Figure 1). A total of about 125 acres was inventoried, mostly on private surface. Along the west half of the seismic corridor about 36 acres of state surface in sections 23 and 24, and 3.4 acres of federal surface in Section 23 surface were surveyed. The remaining 85.6 acres were private surface. The objective of this cultural resource inventory was to locate and record any cultural resources that might within the potential area of effect of the proposed project, and to provide recommendations of eligibility to the National Register of Historic Places (Register). Management recommendations for treatment of any discovered resources were to be made in accordance with their recommended Register evaluations and potential impacts. Environment Located in the northern portion of the Southern Rocky Mountains Physiographic Province (Thornbury 1965) the physiography consists of abroad area of rolling, dissected uplands west of the Yampa River Valley and northwest of the Williams Fork Mountains. The The terrain around the project area is an area of broad gently sloping ridges bounded by shallow gulches and draws containing intermittent drainages. The terrain becomes steeper to the east toward the Yampa River and Williams Fork Mountains. Project elevations range from about 6150' amsl near the Yampa River, to about 6500' near PEDS-15-alternate. The proposed drill hole locations are predominantly on ridgetops or gentle slopes. The proposed seismic line climbs west-southwesterly from the Yampa river Valley across deeply dissected upland ridge terrain.
