These wells will <br />be used to establish baseline water table elevations as they exist <br />on the ranch now, and to detect changes in the water table elevations <br />which may occur after mining operations commence, <br />Enclosed is a copy of the 1" = 200' aerial photo on which I have <br />marked approximate locations of the wells. As we discussed in the <br />field, I have numbered these wells 9 through 17, wells 1 thrcugh 8 <br />being those drilled in 1974• <br />Also enclosed is a table summarizing depth of overburder, depth <br />to shale and depth of casings for these 9 wells. <br />We understand that you will measure the water levels until such <br />time as we hear differently from you, <br />If you have questions concerning this, please call, <br />Very truly yours, <br />W, W, WHEELER AND ASSOCIATES, INC, <br />Kurt A.
