Section 785.19 (c) Continued. <br /> <br />Bush Draw is an intermittent stream valley which drains 4.8 square <br />miles. Stream-laid deposits were found on the surface and in <br />backhoe pits in the draw along the valley bottom. A narrow flood- <br />plain is present in the draw, except in several locations where the <br />valley narrows and the stream channel is bounded on both sides by <br />bedrock outcrops. <br />Williams Draw is an intermittent stream valley which drains 4.5 <br />square miles. Stream-laid deposits were mapped in the draw along <br />the valley bottom. The same type of geomorphic characteristics <br />found in Bush Draw occur in Williams Draw, i.e., a narrow, discon- <br />tinuous floodplain bounded by bedrock outcrops. <br /> <br />1 <br />Sudduth Draw is an intermittent stream valley which drains 3.8 <br />square miles. Stream^laid deposits are present all along the <br />stream valley in a floodplain approximately 200 feet wide. The <br />geomorphology of the stream has been altered by the construction of <br />four small stock ponds in the mine plan and adjacent area. The <br />floodplain of Sudduth Draw was apparently continuous along the <br />length of the draw prior to the construction of the ponds, although <br />the dam of each pond was built completely across the floodplain and <br />mapping the exact outline of the stream-laid deposits is not pos- <br />sible. With this one exception, the distribution of stream-laid <br />deposits in Sudduth Draw is identical to that of Williams and Bush <br />Draws. <br />Litholbgy bf'IIdc6nsblidatAd"Deposits <br />From logs of backhoe pits and surface observations, the stream-laid <br />deposits of Bolton, Bush, William and Sudduth Draws, shown on Map <br />16, Kerr Mine Area Surface Water Hydrology, were nearly identical <br />and were found to consist entirely of clayey alluvium with very <br />little gravel or sand material, as shown on Map 40, Kerr Mine Area <br />Stream Channel Cross Sections.
