A file search of the Colorado Inventory of Cultural Resources by the Colorado Historical Society <br />revealed no cultural properties in the proposed impact area. These results are presented in <br />Exhibit 7, Archaeologic Information. <br />The intensive field investigations recorded no significant cultural resources. The only <br />phenomenon of cultural origins observed in the area was a stock pond, located in the drainage <br />bottom immediately north of the highway (Figure 2, Regional map Showing Locations of Project <br />Area). This feature consists of an earthen dam piled in a curvilinear shape across the width of <br />the drainage. A small pond (now dry) is impounded behind this embankment. It is considered to <br />be of fairly recent age. <br />No significant cultural resources were observed on the PPA. Though the likelihood of <br />cultural resources being found in this area is greater than for the RDA, hat possibility was <br />negated by deposits of underground development waste. <br />No cultural resources were recorded in the proposed project area. Consequently, no <br />further archaeological work is considered to be necessary in those localities and clearance is <br />recommended. <br />2.04.5 General Description of Hvdrology and Geology <br />2.04.5 (la, b and c) <br />A thorough description of the geology and hydrology, including surface and <br />groundwater systems, water quality and water quantity within the proposed permit area and <br />region are contained within the following sections of 2.04.6 and 2.04.7. All pertinent <br />information on the geology and hydrology, as set forth by the regulations, are made available to <br />the Division. <br />Geologic and hydrologic maps of the mine plan area (Map 5— Regional Geology, Map <br />6— Surface and Bedrock Geology (Refuse Area) and Map 8— Regional Hydrology) present <br />the baseline conditions in the proposed permit area. Due to the proximity of the Golden Eagle <br />and New Elk Mines to each other, historical baseline data for both mines have been considered <br />in defining the geologic and hydrologic environments. <br />2.04.5 (2) <br />Approved hydrological modeling techniques have been utilized as part of this permit <br />application and data used in modeling is made readily available within the document in 2.04.7. <br />Coal seam correlations, cross - sections, structure maps, interburden maps, overburden maps and <br />isopach maps were generated by the use of Carlson's SurvCADD software which is commonly <br />used in the coal mining industry. <br />TR56 <br />2.04 -8 Revised 1 /10 /11 <br />
