• 2.7.7.4 FLAME GQLCH <br />An evaluation of the Flume Gulch alluvial system relative to <br />an alluvial valley floor (AVF) follows. This section presents the <br />geologic setting, ground water and surface Water conditions, soil <br />and vegetation and land use conditions for the Elume Gulch area. <br />2.7.7.4.1 GEOLOGIC SETTING <br />Map M-58 presents the location of the Flume Gulch drainage in <br />the Trapper Mine permit. This location map shoos the locations of <br />drill holes and cross sections used in defining the Flume Gulch <br />system. A geologic cross section from wells GP-9 through the Coy <br />test hole and Wells GC1 and GP1 is presented in Map M-59. This <br />geologic cross section shows the geologic setting of the Flume <br />• alluvial system. The other main aquifers of concern in this area <br />are the Third White Sandstone, the H and I Coal Seams, the KLM <br />sequence of coals and the QR aquifer system. These beds dip to the <br />north, similar to the remainder area of the Trapper Mine. Shale <br />~v`"''= lenses between the aquifer systems separate these aquifer systems <br />•~-':~`' from being readily connected. <br />':`:.. <br />=;~: Map M-58 presents the locations of three alluvial cross <br />sections in Flume Gulch. The GT site geologic cross section was <br />developed on the eastern branch of the Flume Gulch and is called <br />the GT area. The GC cross section is located at the GC well sites <br />and the Coy cross section is located at the Coy alluvial well site. <br />The Coy alluvial site is below the confluence of both the GT and GC <br />sites. 98PIS®I!/W/92 <br />
