MCC's B-Seam longwall panel directly to the south in Section <br />20 extended to only l,(00 feet of the Section 17 south line and that would be too fa3 <br />away to have impacted the crack area. <br />Therefore, we have a unique situation where to the north, two seams (B and C) were <br />mined to a bamer pillar directly beneath the crack location. To the south, the F-Seaul <br />was mined to witiurt IOC to 200 feet of the crack. C-Seam mining, to the south, probably <br />also had an impact on the site. In short, we had two seams to the north and at least one <br />to the south which, when [Wined, in effect lowered the strata against a rigid barrier pillar <br />in two coal seams. The steep slope (approximately 3R degrees or 7S degrees) probably <br />also had an effect on widening the cracks. <br />CDMG's safety concerns can be allayed when one considers the conditions at the site, <br />which is inaccessible, from a practical standpoint. To reach the Site. a person would face <br />a steep climb up 500 feet through thick oak brush. The sandstone cliff below the crac6~ <br />can be scaled with difficulty in only a few places. From above, dte descent and <br />negotiation of the sandstone cliff above is equally difficult. Any person who negotiated <br />the access would certainly be expected to avoid stttmbling over the crack. <br />I saw no zvidencz of livestock activity on the ridge or the slope above the bottom of Lone <br />Pine Gulch. Access to the area of the crack would be diffictilt for domestic livestock. <br />Any that did reach the site would find the crack much less of a hazard than the cliffs, <br />landslide cracks, and steep slopes of the area. <br />Deer utilize the area, but they and other wildlife would have little problem in avoiding <br />the crack. The crack would likewise be less of a hazard to them than the cliffs, landslide <br />cracks, and natural terrain they nomtally traverse <br />I offzr no suggestion on sealing or covering the crack because it does not pose a concept <br />and it is healing itself. <br />831-U32~130cblwetl-mem jr <br />
