Landslide and Hillslope Deposits <br /> • The dip slope conditions present on the west side of <br /> Huntsman Ridge and the naturally unstable slopes of the Mancos <br /> shale have resulted in a number of mapped and apparent <br /> landslides within the Coal Basin Mine adjacent area. The <br /> locations of these landslide features are shown on <br /> � —17 Landslidesin the Mancos shale and, in general, <br /> all landslides are characterized by a hummocky topography <br /> and poor internal drainage. Seeps and springs are prevalent <br /> but do not necessarily represent a potential water supply. <br /> The spring present in the SE/4, Section 14, T. 10 .S , R. 90 .W, <br /> is probably a seep in a landslide deposit as indicated by <br /> the topography of the area. <br /> • Glacial activity has resulted in -the deposition of a number <br /> of gravel veneers and areas of glacial till on the western <br /> Z-x. ,4j� ZIP- C- f <br /> slopes of Huntsman Ridge, (Sees--I) . These <br /> glacial deposits probably have sufficient porosity to store <br /> water and probably become water saturated during spring <br /> runoff. However, these deposits are thin, limited in lateral <br /> extent and are not considered a significant aquifer within <br /> the- mine plan and adjacent area. <br /> 23 <br /> - !I <br />
