Limited - Results Archaeological Survey Form (Page 4 of 8) <br />IV. ENVIRONMENT (cont) <br />21. Ground Visibility: Surface visibility is generally good and averaged 40% in the natural <br />environments found in the east half of TCW009, all of TCW010, 11 & 12. In the CRP portion of <br />TWC009, and areas next to drainages, visibility decreased to around 10% or less. TCW008 is in <br />the floodplain of Fish Creek and visibility was extremely poor (0 %) due to thick grass growth. <br />The waterline /pipeline segment is also near 0% visibility due to the thick vegetation resulting from <br />the damp nature of the environment. <br />22. Comments: Special attention was paid to areas of exposed soils and subsurface contents in <br />cut banks, eroded areas and rodent backdirt piles. The waterline /pipeline segment follows a <br />newly constructed road that afforded good views of subsurface contents. \ <br />V. LITERATURE REVIEW <br />23. Location of File Search: OAHP - Compass online database; GLO records online <br />Dates: 04/12/2012 <br />24. Previous Survey Activity - In the project area: The core hole drill sites and 300 ft of the <br />waterline /pipeline route have not been previously surveyed. The remaining portions of the <br />waterline /pipeline were surveyed during the West Mine Subsidence block survey which covers <br />portions of Sections 22, 23, 24, 25, 26, 27 in T5N R87W and Sections 17, 18, 19, 20 in T5N <br />R86W (O'Brien 2007). <br />In the general region: In addition to the West Mine Subsidence block survey (O'Brien 2007), six <br />previous inventories have been conducted within sections 27 and 35 (Table 1). <br />25. Known Cultural Resources - In the project area: No previously recorded archaeological sites or <br />isolated finds are located within the project boundaries. The 1882 & 1915 GLOs reveal no <br />historic features within the protect areas. <br />In the general region (summarize): Three cultural resources have been recorded within the two <br />sections. All have been evaluated as not eligible and are more than '/4 mile from any of the <br />survey areas. The 1915 GLO shows a historic fence line in the northern half of section 35 and <br />an irrigation ditch in the southern portion of section 27. No evidence of either of these features <br />was encountered during this inventory. <br />
