man Ridge. The rare areas of moderate terrain associated <br /> • principally with the southern part of the basin , suggest <br /> glaciation. So does the occurrence of tarn and kettle hole <br /> lakes , interrupted drainage, and moderately to poorly <br /> developed lateral and terminal morraines in the upper reaches <br /> of the Bear , Dutch, Oilwell and Coal Creek drainages . <br /> On the western side of the Huntsman Ridge , <br /> glacial activity has deposited thin gravel veneers and <br /> created areas of glacial till . <br /> The west side of Huntsman Ridge is also <br /> characterized by a number of landslide areas , due to the dip <br /> slope conditions and the unstable slopes of the Mancos <br /> Shale . The landslide areas have generally hummocky topo- <br /> graphy , and poor internal drainage . <br /> 4 . Regional groundwater information. <br /> a . Introduction <br /> Mid-Continent Resources , Inc . , assisted by <br /> the consulting services of Willard Owens and Fugro Rocky <br /> Mountain, Inc . , has evaluated groundwater characteristics of <br /> the Coal Basin and adjacent areas . See Willard Owens <br /> Associates , Inc . Coal Basin Hydrologic Report at appendix <br /> III-E-1. Data for the evaluation was obtained from the USGS <br /> and the United States Forest Service (USFS) , as well as from <br /> domestic wells , Mid-Continent ' s drill hole logs and geologic <br /> maps . The following describes the discharge, recharge , <br /> storage and transmissivity aquifer characteristics . Detail <br /> • <br /> 15 <br />
