PG. 57 7/23/59 Morning - climbed from the "Hess" ledge up to the second Leonard limestone - made three collections based on King's Sect. 12. The base of the Capitan at Sullivan peak is a beautiful unconformity - 40' or more relief and parallel bedding. Afternoon - base of little knob of Coopers' SW end of Lenox Hills - base of hill shale and siltstone and sandstone dip 10° to the S10°W. note: illustration: Bed 1: First Ls, 35'. (3) Collection, C (Top). Bed 2: S.s., orange-brown shale-gray. 85'. Bed 3: Limestone, 3 Coll. 60', Second Leonard limestone.(Coop's Knob) This section is cut by a fault or faults and the exact relation of the knob is dubious - it is probably the second Leonard limestone, but? PG. 58 The Leonard fm in the Lenox Hills consists of series of limestone tongues which tend to become thinner to the SW and break up into a number of thin units by additional shale tongues. The structural problems are big especially in the area south of Sullivan Peak, between Dugout Mt. and the Altuda uplift. Of course, it is all covered but there is still a real problem to figure out. King's map is wonderful, but his isn't very consistent about his boundary between the Word and Capitan - his Leonard and Word also have problems - the Ammonite bed which he places in the Leonard in the west is about the right horizon for his first Word limestone in the east. i.e.,[?] It seems the Word- Leonard boundary is also inconsistent. The base of the Word in the west seems to be about the third limestone of the eastern Mts. In Section 12 this unit is greatly thickened and may represent the reef between PG. 59 the hash reef faces to the east and the basin to the west.
