Although the elevations will be somewhat different, it is <br />elevation and dip of the sandstone channels, as well as the top and base of the Bowie <br />reasonable to assume that the E Seam contours in (Figure 17) also define general <br />Sandstone. The dip of the sandstone channels range from parallel to perpendicuIaz to the <br />dip of the E Seam. For the most part the sandstone channels dip 2-3° to the northeast. <br />Evaluation of Potential Groundwater Inflows <br />Associated with E Seam Mining, <br />West Elk Mine, Somerset, Co]orado <br />59 <br />February 24, 2004 <br />
