As stated in the attached Memorandum from Dr. Jim <br />Pendleton, this report contains a straight forward rendition of the survey data for Mountain Coal <br />Company's numerous subsidence monitoring points. With the exception of the visual monitoring <br />discussion contained in the report, the brief cover letter discussion and detailed data report are <br />acceptable in regards to monitoring observations. However, please indicate the location of <br />cracking and "scars" on the subsidence map. Also, please provide indications of crack extent, <br />date of first observance, and notes concerning subsequent "healing". Please submit revised report <br />maps and text as appropriate. <br />If you have any questions please contact me of Dr. Jim Pendleton. <br />Sincerely, <br />Michael P.
