Scenic Values Study • < i LITHOLOGIC LOGS The lithologic logs present a description of rock types from the surface rocks encountered in a coreholc to total depth. The detail of description varies with depth and operation. In most cases, however, the lithology is described from drill cuttings on ten- foot intervals above the "A" groove where drilling is the common practice. In the lower zones, the lithology is described from cores on one- foot intervals. In addition to providing a means for describing lithology, the litholog presents additional required data such as information on structural dip, joints, fractures, and general rock quality data. This data is entered in the lithologic log at the appropriate depth. The log then presents a depth record of rock type and structure. A field lithologic log has been made on each well drilled prior to November 30, 1974. Table II B-l (pp. II B-7 through II B-12, Volume I) shows those wells for which a lithologic log exists.
