17) Limestone, gray-brown weathering, platy fragments of shells, mostly [potato chip?] brachs, algal. 1' to 2' beds - overall weathering creamy - 7'. 18) Covered 21'. 19) Limestone, (calcarenite) with some quartz 1--20%, cherty or quartzite pebbles 1% or less; weathers a medium brown-gray, whitish speckles - wavy uneven bedding, 1" to 2' thick; 55'. The upper 40' become very quartzite - about 85-90% SiO2 excluding cement. Becomes poorly cemented upwards. 20) Covered, 45', probably like unit 19, see note on page 112. 8/22/58/7 and 7/17/57/9. 21) Limestone, massive, brownish-gray weathering; [Transfer bed] solutions bedding in 6" to 1' intervals, but not much "true bedding" 31'. Biohermal reef, very light gray on fresh surface, very fine grained, probably mostly recrystallized? 22) Covered, 9'. 23) Limestone, brown-gray weathering, dark gray or fresh surface. Coll. 8/22/58/6. PG. 111 {note: illustration: bed 20: 7/17/57/9 bed 21: 7/17/57/10 bed 23: 7/17/57/11} 24) Covered, 20'. 25) Limestone, weathers orange-brown, has brown (Iron stain) chert nodules - 9'. 26) Covered, 36'. 27) Sandstone, quartz grain, medium; Calcareous cement. Brown and green grains, chert and quartzite pebbles (1/4" diameter to 1/2"). Some massive beds, some in 1/4" laminar. 31'. 28) Conglomerate; has some sand in it as 27, just that pebbles become 4" to 8" diameter and up to about 75 to 80% of lithology. PG. 112 There is almost no limestone in this conglomerate, but it still seems to be the "Hess" conglomerate. In other beds limestone boulders and cobbles are as high as 70%. #20 In the stream draw, interval 20 is exposed. Calcareous shale and sandstones, rich fusulines free in slope wash. Collection 7/17/57/9. White to light cream weathering. Becomes more Calcareous and grades 2-3' into wavy bedded base to biohermal reef. 35'-40'. The #4 and #5 limestone of King's Gaptank appear to have beginnings in the "Uddenites" zone just to the west of Gaptank. I find no field evidence which would assign a Wolfcamp age to King's W.C.L.s in this area. It is not until we get above that unit that we find a distinct break in lithology.
