r~ <br />u <br />Revised 1/26/80 <br />Section 785.19(c) Continued <br />As stated previously, the data collected in the study area can be extrapo- <br />lated so as to apply to the entire xeacki of Foidel Creek in the adjacent <br />area. Lithologic logs of the alluvium along Foidel Creek have been <br />provided in Exhibit 8, Drill Hole Logs, for wells W-5, D-14, Sw-6, <br />FM-1, SW-7, D-6, Ste, SIr6, FS-1, Irl, W-26, W-28, D-5 and S-5. These <br />wells are shown on the Twentymile Park Hydrology Insert (Map 6). A <br />cross-section has been prepared using wells which forma transect across <br />the floodplain in Section 29, Township 5 North, Range 86 west, entitled <br />Stream Channel Cross Section H (Insert to Map 51). The lithologic logs <br />• show that the alluvial material and stratigraphy can be correlated from <br />the study area downstream through the adjacent area. This fact should <br />be expected, since the bedrock source material for the alluviuun is <br />identical throughout the reach of Foidel Creels adjacent to Energy Mine <br />No. 1, as Shawn on Geologic Cross Sections E-E', F-F', G-G' (Map 10). <br />AS shown in Stream Channel Crass Section H (Insert to Map 51), the <br />alluvial crater table is well below the root zone, just as it is in the <br />study area. The water in the few isolated gravel pockets is confined by <br />inQernieable clay all along Foidel Creek in the adjacent area, preventing <br />natural subirrigation fran occurring. <br />Color infrared aerial photography also danonstrates the absence of <br />• subirrigation. See the discussion under the heading, Aerial Photograph <br />Analysis under this section. <br />785-9(aa) <br />
