The notes do not indicate the surveyor calculated an elevation for PT A from the raw data. <br />Further review of the data in the subsidence file indicate subsidence survey information for a <br />control point "A"listed under the heading East Panel Subsidence Markers. Control Points. The <br />data listed for this point for August 1994 is as follows. <br />Point Date Northin Eastin Elevation <br />A Au ust 1994 ]696.21 -95235.88 7116.72 <br />Review of Map 17, Subsidence Points, received October 6, 1995, indicates the point labeled "A" <br />is slightly west of the 3rd North mains, some 7500 feet east-southeast from the First North <br />workings. This map clearly and accurately depicts a point "A" at the northing and Basting <br />coordinates listed. Note that the elevation listed for the Terry Survey conducted January 8, 2001 <br />for PT A is also 71 16.72, identical to the August 1994 elevation. I believe that this is the point <br />that is being referenced by Mr. Terry when he states under the 1/8/2001 footnote "PT A was used <br />as the benchmark (E1r71 16.72)". However, without a map or sketch from the January 8, 2001 <br />survey, it is not clear where a~ of the points are located. Although it can probably be accurately <br />assumed, I believe this situation warrants accuracy and elimination of any confusion, speculation, <br />or ambiguity. In addition to the survey data, a map or sketch clearly rndreatirrg the location of <br />the four panrts included in the Terry survey is necessary. <br />CC: Walton Morris, attorney <br />S[eve Brown, AG office <br />
