- 11 - <br />• obtained during the excavation of the existing gravel road. <br />This material was hauled or pushed for a short distance from the <br />site of the excavation and dumped onto the natural grade below <br />the road. Material of these fills consists mostly of sandy and <br />clayey soils with a significant percentage of gravel and larger <br />boulders. The fills are clearly visible on the steep valley <br />sides below the road. We do not expect that their thickness is <br />of any significance. The .road surface and some excavations in <br />the main valley were also identified as manmade fills. <br />Alluvial deposits are deposits of the t9unger Creek and <br />its tributary. They are typically flat, forming uniform surfaces <br />that are interrupted only by the local erosion of the present <br />i creeks. They consist mostly of silts or clayey silts with occasional <br />boulders. A disturbed sample of these alluvial soils (sample No. 5) <br />was taken for testing (see Appendix A). <br />Terrace_dePosits have been identified in several haul road <br />cuts in the road section that follows the tributary of the Munger <br />Creek. The origin of these terrace deposits was discussed in the <br />previous section. They are apparently remnants of considerably <br />extensive terraces (their thickness is on the order of several tens <br />of feet). They consist of horizontally stratified layers of sandy <br />gravel or sand, with rounded pebbles, cobbles, and occasionally <br />larger boulders. The angularity of the gravel indicates a limited <br />length of transport. These deposits appear to be well consolidated. <br />• A sample of these soils was tested (sample No. 3) We feel that the <br />
