2.04.6 GEOLOGY DESCRIPTION <br />The following discussion focuses on the geology of the Southfield mine <br />area. In the Southfield loadout area, there will be minimal disturbance <br />of in-situ materials since the loadout facilities are constructed on fill <br />material which will remain following reclamation. Accordingly, the <br />discussion of loadout area geology is limited to stratigraphy of the first <br />25 feet below the surface. <br />With respect to the Southfield mine area, the geology of all areas to be <br />disturbed by mine operations is described down to and including the <br />stratum below the lowermost coal seam to be mined. As discussed in <br />Section 2.05, Operation and Reclamation Plan, no aquifers have been <br />encountered in underground mine workings or boreholes completed to depths <br />in excess of 160 feet below the lowermost Red Arrow coal seam. <br />Location <br />The Southfield Mine is located approximately 8 miles south of Florence, <br />Colorado on County Road 92. The Southfield loadout facilities 'are located <br />1.5 mile west of Florence, Colorado along County Road 79. The locations <br />of both mine and loadout facilities are shown on Figure 1, General <br />Location. <br />To o ra <br />The configuration of both the mine and loadout areas at the time of the <br />original Southfield permit application (1981) is shown on the Mine Area <br />Pre-mining Topography Map (Map. 6), the Mine Area Pre-Mining and Post- <br />Mining Cross-Sections Map (Map 7), and the Loadout Area Surface and <br />Groundwater. Hydrology Map, (Map 13). <br />Topography of the Southfield mine area is typical of the Canon City Coal <br />Field. The area can be characterized as a high plains mesa dipping gently <br />to the east - northeast. This mesa feature is dissected by several <br />
