the benches, and determine the orientation. This was done for each trench <br />prior to actually logging its geology. <br />Trenches were measured and logged beginning on May 6th after the backhoe <br />had left the property, and continued until 1100 on May 8th. The location of <br />the trenches is shown on Maps A and B; the geology of the trenches is shown on <br />the cross section of each trench. Logging the trenches presented no unusual <br />difficulties. <br />Geolo <br />In general, no unusual geologic features were exposed in the trenches. The <br />cuts all exposed weathered materials derived from nearby rocks. Most of the <br />materials ranged from clay to shale, with a lesser amount of fine grained sand. <br />Weathered shale, and sandstone were common; unweathered sandstone was less <br />common than its weathered equivalent. Definitive correlations of materials <br />• could not be made between trenches. It was apparent that the materials exposed <br />were essentially lenticular in nature. <br />Bedrock was not exposed in any of the trenches; although some of the <br />material exposed in Trench 7 appeared to be close to bedrock. <br />The major difference noted in materials exposed was that Trenches 6 and 7, <br />both of which were on the west side of the drainage exposed a dark gray and <br />brown, to black humus and soil cover, in considerable contrast with the light <br />to dark brown clayey to sandy soil cover exposed in all the other trenches (A, <br />1, 2, and 3). <br />A particular effort was made to determine evidence of slip planes, and of <br />recent ground movement. Nothing was found that indicated the development of <br />slip planes, nor was any evidence found for recent ground movement.
