-2- <br /> These breaks were all parallel to the strike of underlying <br /> longwall panels 101/1 2 (B bed) and 208 (M bed ) . They were <br /> extremely limited in �ateral extent and occurred in a single <br /> isolated area no more than 50 ft by 200 ft . No offset was <br /> noted on any of these breaks . Smooth edges and in-wash <br /> mending indicates the e are older cracks ; this specific area <br /> had not been previously detected. A single break down and <br /> away from the ridge t p gave the appearance of having <br /> occurred this year (g een plants in dirt clods had fallen <br /> into the crack) . Thi feature could be traced for a couple <br /> of hundred feet, from the meadow to the ridge line . Minor <br /> offsets were noted in a few places. Mending by in-wash of <br /> soil material was not d to be underway. <br /> After discovery of th se breaks the rest of the meadow was <br /> examined extensively, albeit not exhaustively. No <br /> additional cracking o other potential subsidence features <br /> were observed. <br /> The cracks described �n the fall of 1988 had not enlarged, <br /> and in fact only portions of them could be found, much of <br /> their original extent having been filled in by surface wash <br /> or frost heaving . Th� pond located in the ancient slump <br /> block between the larger crack and the nearest mined-out <br /> area was full , again no additional cracking <br /> toward these old work;ndicating <br /> . <br /> The area will be reexamined during the 1991 summer field <br /> season. <br /> If you have any questions or require any further <br /> information, please s advise . <br /> Very truly yours, <br /> Bruce A.
