beds 8-11: 5' total} 9) Sandstone, fine grained, yellow to gray-brown weathering, 6" (calcareous-quartz). 10) Shale gray, mostly covered 2'. 11) Sandstone, fine grained, orange-brown weathering, calcareous-quartz. 8" to 1'. PG. 88 12) Shale, brown to gray with 1" to 3" beds of siltstone and sandstone (fine) poorly indurated. 22'. 13) Covered 23'. 14) Sandstone, brown to yellow weathering in 3" to 6" beds, gray on fresh surface. Calcite cement and some calcite grains <30 to 40%. Crossbedding 1/2" to 1" fine to very fine sand well sorted; I believe this to be either eolian or back beach, maybe a little of both. 27'. 7/11/57/3. 15) Covered 18', limestone rubble? 16) Dolostones, 45'+ brown weathering. Above are undoubted Hess beds of general position and lithology in 19 through 21 of section 8b. PG. 89 Section 28 contd {note: illustration: bed 14: 7/11/57/3} Really need to work this out on photos! PG. 90 Section 31 Section 13a - 1/4 mile east of section 11, up front of lower ridge - To top of hill 4752 Section 27 of King. 11) Limestone dark gray, (Gaptank) looks like biohermal rubble - 3" to 4" diameter blacks 5.5' massive 7/11/57/4. 12) Limestone, rubble, dark gray, in 3" beds, very uneven 1.5' 13) Limestone, like #1, upper 3' is 8" to 1' beds, lowers 9' massive, weathers to irregularly pocketed, but rather smooth masses. 7/11/57/5. 14) Sandstone, fine grained weathers orange to yellow-brown, some green color in patches. 3" to 6" beds; 3.5'. 15) Covered, but seems to be a dark red-brown shale zone - This is same color as is at top of Wolfcamp 3/4 mile west. 7/11/57/6, 7'. 16) Calcarudite - all sizes, up to about 2" diameter. Small pieces of Tensus? chert and other cherts, subangular to subround. Upper 1' organic frag. 9'. PG. 91 {note: illustration: Section 13a:
