7/24/58/10 - Creek bed - Word fm between third and fourth limestone 5 +- miles NNE along road to Hess Canyon. 7/24/58/11 - #4 limestone Word fm at head of "Hess" Canyon on King's Map (at L4). PG. 93 7/24/58/12 - Vidrio fm, silicified brachs (not fusulinids, however), a few hundred yards down "Hess" Canyon. PG. 94 7/25/58 Hess Ranch near eastern side (see photo). Lower portion of Hess mbr is dolostone with one fossiliferous limestone near base of exposed section - Unconformity at top of dolostones a foot or so relief-fossiliferous limestone above. Collection 7/25/58/1 - 7' above the unconformity between beds 3 and 4 of King's section 23. Collection 7/25/58/2 - ledge of lower Hess mbr forms prominent sets of "levels" about 1/3 to 1/2 up slope. Anthill. Bed 5, King's Sec. 23. Collection 7/25/58/3 - a second break in slope about 150' to 200' about Coll. 2. Anthill. Bed 7, King's Sect. 23. Collection 7/25/58/4 - about 60' above collection 3; at a small stone carn (limestone full of fusulines) Bed 8, King's Sect. 23. Collection 7/25/58/5 - Anthill just below sponge reef in upper Hess mbr of King's Sect. 23. Bed 13, King's Sect. 23. Collection 7/25/58/6 - Anthill above first ledge of Sponge reef - This is near top of Leonard fm. several beds of silicified limestone above, forms dip slope to lower Word escapement. Bed 13, King's Sect. 23. PG. 95 7/25/58/7 - Anthill about same horizon as (7/25/58/2) perhaps 10' below, 1/4 mile west along Leonard escapement. Bed 5, King's Sec. 23. 7/25/58/8 - from isolated outcrop. 3/4 mile NW of Hess Ranch House. The lower 50 or 60 feet are dolostones with a few relic fossils impressions. The upper 30 feet are silicified thin limestones with some zones of unaltered limestone - contains bryozoans and crinoid columnals. PG. 96 7/26/58 Decie Ranch 7/26/58/1 (= 7/31/57/1) - bed 12 of Sec. 20 brachs and fusulines. 7/26/58/2 (= 7/31/57/3) - Sec. 20, bed 15. 7/26/58/3 (= 7/31/57/4) - Sec. 20, bed 17. 7/26/58/4 - Section 20, bed 22,23,24 - The fusulines look similar from all of these beds in field - mostly the free specimens are from the shale break or lower calcarudite - hand sample from upper part. Bryozoans common in upper 1'.
