Box .161. <br />Silt Co. 81652 , <br />i <br />Re: Subsidence Monitoring <br />I certify that on February 28, 1990 I conducted a field <br />survey to monitor the position of Subsidence Monument No. 2. <br />and Monument No. 8. Listed below are the results of that <br />survey: <br />North Coordinate East Coordinate, Elevation <br />Monument #2 8466.260 10263.457 6753.16 <br />Monument #8- 81'18:448 1025.202 6883.29 <br />i <br />The survey is based on coordinates of N 8725.513, E 8958.266 <br />at the backlight point (Rebar & Cap) named Mine. This point <br />is also the benchmark for vertical control having an <br />elevation of 6347.00. Coordinates for the setup point (iron <br />stake near tire) are N 8683.647, E 8275.055. <br />This survey meets or exceeds Second Order, Class II survey - <br />standards. <br />/.~~~~~ <br />_, Richard L..
