MCC's B-Seam longwall peael directly to the south in Section 20 extended to only 1,100 feet of the Section 17 south line and that would be too far away to have impacted the crack area. ~ Therefore, we have a unique situation where to the north, two seams (B and C) were mined to a barrier pillar directly beneath the crack location. To the south, the F-Seam was mined to within 100 to 200 Feet of the crack. C-Seam mining, to the south, probably also had an impact on the site. In short, we had two seams to the north cad at least one to the south which, when mined, in effect lowered the strata against a rigid barrier pillar in two coal seams. The steep slope (approximately 38 degrees or 78 degrees) probably also had an effect on widening the cracks. CDMG's safety concerns can be allayed when one considers the conditions at the site, which is inaccessible, from a practical standpoint. To reach the site, a person would face s steep climb up 500 feet through thick oak brush. The sandstone cliff below the sack can be scaled with difficulty in only a few places. From above, the descent cad negotiation of the sandstone cliff above is equally difftcult. Any person who negotiated the access would certainly be expected to avoid stumbling over the crack, I saw no evidence of livestock activity on the ridge or the elope above the bottom of Loae Pine Gulch. Access to the area of the crack would be difficult for domestic livestock. Any that did reach the site would find the crack much lass of a hazard then the cliffs, landslide cracks, and steep slopes of the area. Deer utilize the area, but they cad other wildlife would have little problem in avoiding the crack, The crack would likewise be less of a hterard to them than the cliffs, landslide cracks, and natural terrain they normally traverse. I offer no suggestion on sealing or covering the crack because it does not pose a concern and it is healing itself. Ir I •U32~ t)(ICE~well•mem j.
