Alluvium Depth <br />Map <br />In order to establish the alluvium depth the exploratory drill hole logs are the only available sources of <br />actual measurements. Since there are no drill holes in the flowline of Newlin Creek, the drill holes upon <br />the tops of thestreambanks of Newlin Creek were utilized .SThe depths to the consolidated layers in <br />these drill holes are shown in Table 1. The alluvium is the unconsolidated layer, composed of sand, <br />gravel, and boulders. <br />Table 1. <br />Drill hole Alluvium Depth, ft. Streambed Valley Depth, ft.
