Slope on the hillside is rather steep, varying between 70 <br /> and 300. Many intermittent drainages cut this side of Huntsman ridge, and <br /> several active springs (some as high as 11,000 feet) were observed in the <br /> study area, providing year-round sources of water. <br /> Each of the proposed drill hole sites is located in a clearing. Pad <br /> • #1 sits beside an intermittent drainage, approximately 1,000 feet below the <br /> ridge top; Pad #2 is located at the head of an intermittent drainage, only <br /> 400 feet below the ridge top; Pads #3, #4, and #5 occur on the tops of small <br /> ridges emanating from Huntsman Ridge. <br /> Access to the study area is gained by traveling south from Carbondale <br /> approximately 16.5 miles on Colorado 130 to the Coal Creek road (intersecting <br /> from the west) , which is followed approximately 7.5 miles to Mid-Continent's <br /> #4 mine. One then ascends Huntsman Ridge (via the drainage to the southwest), <br /> from which access to the study area is gained. (See map.) <br /> Geology/Soils <br /> The upper part of the Mesaverde Formation underlies the study area. <br /> These beds were deposited during the Upper Cretaceous period and consist of <br /> interlayered sandstone, shale, and coal beds (Tweto, Moench, and Reed 1978) . <br /> Large sandstone boulders are scattered throughout the study area, especially <br /> near the top of Huntsman Ridge. <br /> Soils in the study area are dark, shaley/clayey loams, formed in re- <br /> siduum from the underlying sandstone, shale, and coal beds. They are shal- <br /> low and fairly dry near the upper elevations of the study area, becoming <br /> • more moist lower on the ridge. <br /> 2 <br />
