Mined Land Reclamation October 3, 1985 Page 2 <br />Station U-8 was set within 207 feet east, and 99 feet south <br />of the requested coordinates. This position was chosen so <br />that reference stations D-11, D-12 U-AI and U-T2 could be <br />seen. In addition, new station U-11 could be seen. <br />Station U-10 was set within 21 feet east, and 5 feet north of <br />the requested coordinates. The terrain was extremely steep. <br />Oak Hrush and Euck Erush was very dense. The final location <br />was selected so that reference stations D-il and D-12 could <br />be seen through the timber. No other stations can be seen <br />from U-10. We left a 510.00 prism on Station U-10 so it <br />would not be necessary to return to it again. It is not <br />possible to occupy U-10 with an instrument. All monitoring <br />will have to be accomplished from D-11 and D-12. U-10 is <br />located on a dormant landslide. The area is well vegetated <br />and does not show evidence of slipping for the past several <br />years. I am certain, though, that the area will slide again <br />simply because it is very steep, and not due to mining <br />activity. <br />Station U-11 is located approximately 150 feet west of the <br />center of a drainage channel. It is located on a steep brush <br />covered slope at a paint 495 feet west, and 215 feet north of <br />the requested coordinates. The final location was chosen so <br />the point can be seen from D-10, D-11 and U-8. The soils in <br />which U-il was set appeared to 6e deep, loose, moist soils <br />with a large quantity of organic material. I anticipate some <br />apparent movement of U-11 due to our inability to establish a <br />stable station. <br />A description of each sation is: <br />U-8: A ~-inch diameter steel pipe with a 5/8-inch threaded <br />bolt to accommodate the survey instrument. It is painted <br />orange and marked U-8. <br />U-10: A 40-inch length of 1-inch iron pipe driven into the <br />ground 0-inches (it could not be driven further>, with a 10- <br />feet lonq•length of 1 1/S-inch red and white steel range pole <br />set over the pipe. A prism is secureley wired to the top. <br />The range pole was fixed to the pipe by drilling a hole 1- <br />foot above ground and setting a nail for a pin. <br />U-li: A b0-inch length of I-inch steel pipe was driven to <br />ground line, earth was removed and the pipe driven further. <br />It would not became stable. Other sites were not available <br />because I wanted to be able to see U-IS from a minimum of 3 <br />other stations. <br />
