61) Rhyolite? sill. Top of Section cont. King Sect. 24? Collection 7/9/57/3 - from ant hill on small WC knoll, in about horizon of #25 or #26 of section VII. Collection 7/9/57/4 - dark gray limestone in slope of #2 (Gray Limestone) of King Outlier - SE flank. 1/3 of way up from gate - I doubt if it is in place. {note: illustration: bed 1: 10', 7/9/57/5 bed 2: 45', 7/9/57/4 bed 3: 60' bed 4: 25' bed 5: 45' bed 6: 20'} yellow calcaredite, has dark grey limestone cobbles, rusty fine sand and silt matrix. PG. 71 Section 26 Section 8a - 2.5 miles NE of (Taylor) Neal Ranch House lower part of section badly covered. 1) Sandstone, very fine size, yellow weathering - Tetracorals, brachiopods, sponges?, fusulines?. This bed is fairly porous and most fossils are empty molds. 1' to 2'. 2) Covered 12'. 3) Limestone, gray, shell hash, brachs, crinoids, fusuline 9'. Collection 7/9/57/6, 4" to 1' bedding. At top of unit a bed like #1 is capping. 4) Covered 29'. 5) Limestone, gray at bottom (2') <-- 7/9/57/7, 42' above are gray-brown weathering dolostone no fossils identifiable. 2" to 4' beds. 6) Covered 14'. 7) Dolostone, yellow-brown weathering. 1' to 3' beds, 12'. PG. 72 Section 8a runs up a small slope. The various angles of bedding and covered intervals between these outcrops are suggestive of some structural disturbance. Section 8b begins on what I believe is bed 7 of 8a. 8) 69' covered. 9) Sandstone, poorly undulated, very fine sand size, some silt, well sorted however, CaCO3 is common as sand grains - greenish-gray shale yellows. 36', 1" to 3" beds. 10) Limestone, nodular uneven bedding, 3" to 6" beds. Collection 7/9/57/10, 3' above base. 38' (See page 21) Collection 7/9/57/11, 15' above base. 11) Siltstone, pebbly, yellow weathering, some bands are more pebble than silt! 15' poorly cemented. 12) Siltstone with pebbles - siliceous cement 2'.
