2.04.4 Cultural 6 Historic Resource Information <br />• There are no cultural or historic resources listed on <br />the National Register contained within, or adjacent to, <br />Sunland Mining Corporation's permit area. <br />As is detailed elsewhere in this application, eventual <br />subsidence, if it occurs at all, is estimated to be minor. <br />It was calculated that the maximum subsidence over the <br />Lower Pinnacle seam in fault blocks 1 b 2 will probably be <br />between 10 and 39 inches, and that the average over the <br />subsided area would be somewhere between 5 and 28 inches, <br />with the higher figure more likely to be near the outcrop <br />(which is overlain by a very steeply sloping hillside). In <br />fault block 3 where eventually 3 seam mining is being <br />considered, it is estimated that the maximum subsidence <br />will probably be between 12 and 67 inches (based on <br />extraction of all three seams). The type of subsidence <br />expected would be the gentle, trough type, as opposed to <br />the sink hole or pot hole type subsidence experienced in <br />shallower cover where competent roof material is not <br />present. In all likelihood, if subsidence did occur, it <br />would be toward the low side of the above figures. It is <br />our opinion that any subsidence would have negligible <br />effect on cultural resources, especially since none have <br />been identified. <br />During the summer of 1977, Dr. Phil Born of the <br />Historical Museum and Institute of Western Colorado <br />conducted an archaeological survey of the surface areas <br />overlying Sunland Mining Corporation's leases. This survey <br />revealed no evidence of archaeological significance. The <br />cultural resource inventory report submitted to the BLM by <br />the museum (see accompanying report), says in summation: <br />"No evidence of occupation or use of any of the three areas <br />covered by this cultural resource inventory was found. <br />...One must conclude that nothing of recoverable <br />archeological or historical value lies in these areas... <br />and there is nothing in the vicinity to suggest the <br />probable presence of cultural materials lying below the <br />lower level of the root structures. In the absence of any <br />findings of lithic materials, charcoal stained earth, <br />hearths, fire burned stones, bone implements, or any other <br />artifact of pre-historic occupation or use of the area, no <br />mitigating measures are recommended." <br />• <br />!4 <br />
