Limited - Results Archaeological Survey Form (Page 3 of 6) <br />IV. ENVIRONMENT <br />18. General Topographic Setting: The project area is located at the southern end of Twentymile <br />Park, immediately northwest of Fish Creek. The town of Oak Creek is 12 miles southeast of the <br />project area via CR27 and CR37. Both core hole locations are in areas that have been <br />previously impacted via Conservation Reserve Program (CRP) activities. <br />Current Land Use: Livestock grazing and limited hunting. <br />19. Flora: The project area is heavily vegetated with tall grasses and (orbs, with a limited amount of <br />low sagebrush. <br />20. Soils /Geology: Surface sediments are predominantly aeolian in nature and consist of a dark <br />brown clayey loam with few gravels and cobbles. Subsurface geology is composed of <br />sandstone, shale and major coal beds of the Williams Fork Formation which are sedimentary and <br />igneous rocks from the Early Tertiary and Late Cretaceous Age (Tweto 1979). <br />21. Ground Visibility: Surface visibility was poor, averaging around 20 %, due to the thick grass <br />cover. There were several areas affording views of the subsurface contents via animal trails, <br />small eroded areas, and rodent back dirt piles. <br />22. Comments: <br />V. LITERATURE REVIEW <br />23. Location of File Search: OAHP - Compass online database and BLM Little Snake FO <br />Dates: 09/07 & 09/09/2011 <br />24. Previous Survey Activity - In the project area: No previous cultural resource inventories are <br />located within the current project area. <br />In the general region: Two previous inventories have been conducted within the two sections where <br />the drill locations are located. Both of these where performed by Metcalf Archaeology. In <br />section 34, a portion of a seismic line was inventoried in 2004 (BLM 54 -1 -04) and in section 27, a <br />portion of the Cow Camp subsidence project was inventoried in 2008 (BLM 54- 1 -08). <br />25. Known Cultural Resources - In the project area: No previously recorded archaeological sites or <br />isolated finds are located within the project boundary. <br />In the general region (summarize): There are two isolated finds recorded within section 34, but these <br />are over a '/4 mile away. <br />
