8/26/57/10 - near top of King Marine es. unit at east end of Need Horst. This bed is equivalent stratigraphically to bed 7 of section 396. In the middle of this Horst there is a graben elonged (// NE-SW) and sect 396 was measured up the section in the graben, King measured his section E of the graben and apparently based the waycamp line to the west on the lithology change on this part of the glass cliff. 8/27/57/ - Need Canyon. - The fault at the east side of the Horst continues to the S and a little W) and probably causes the structural control on a valley there. It is probably this fault or the homocline monocline fracture resulting from this fault that covered the west end of the waycamp line at the WCHs to a place under the alluvium. The 2 main ridges of the Horst seem to be separated by a fault although this may be an optical illusion on any part. The western hill is covered with King's Lime and has more conglomerate apparently than the eastern hill. There however is what I take to be the top of the waycamp line, a considerable thickness of limestone and shales? (covered elsewhere) and at this "monoclastic internal line" appears to the west along the western hill. The system of faults related to the intrusion seems to be quite complex. The intrusion in Need Canyon is connected by sills, dikes and linearly scattered igneous bodies to the Iron Mt. Intrusion. One system of faults parallels this trend; igneous intrusions and the other
