2' band of nodular limestone about midway in unit. Total thickness 41'. The upper part weathers gray on top. - Top of Gaptank - Base of Uddenites 4) Covered 12', probably brown shale. 5) Limestone, light gray with interbedded brown siltstone - Crinoidal, dark. 5' occasional brach. fragments. PG. 20 6) Covered - 9', probably gray shale and a few brown siltstone bands 7) Limestone, brown weathering, bedding 6", uneven surfaces, Crinoid, brachiopods and a few fusulines. Collection 6/27/57/10 (24-7) 8'. 8) Covered - 12' probably lime nodulars in a clay or silt, some brown colors. 9) Limestone gray, massive a) fusuline and brach coquina in a 6" band at base, Collection 6/27/57/11 (same horizons as 6/26/57/6). b) Massive limestone ledges 4-6' thick. These form the dip slope and seem to be about 10' below what I believe is P.King's limestone #2 bed. 12' thick (?) PG. 21 In the afternoon of 6/27/56, I drove northeast from the Wolfcamp hills to a tank (about 1.5 miles). From there I walked slight west of north to the low outliers of the Wolfcamp and Hess as mapped by P.King. I found silt and sandstones with even bedding exposed in a gully. They would suggest that the conglo. Hess at Wolfcamp Hills is only a local bed or lense. The sandstones are medium lamellae- 1/8" to 1/16" and have abundant tube (or fecal castings) of worms - one I measured was 5" long, 1/4' in diameter and near straight. - About 2' above this silt and sandstone sequence in the rubbly part of the limestone. I made Collection 6/27/57/12. It looks like what C.O.D. said Schubertellia Kingi would look. - 4' above collection 6/27/57/12, I found a brown shale- it had a few streaks of red-brown at the top and some gray in patches- Collect 6/27/57/13 from shale. PG. 22 At this time I'm not too sure of the data, but the deal about shifting and eroding reefs maybe a partial answer to the big picture. Perhaps in well logs we could get the needed 3D perspective on the facies shifts. After briefly looking at the lower Hess, I wonder at what silt, sandstones and cemented siltstones, with a few interbedded limestones might mean with relation to the cyclic Wolfcamp and the irregular and peculiar Uddenities zone. The phases of the biohermal growth in the Wolfcamp must have had other types of deposits elsewhere - could they not be represented in either the Uddenities facies (no because of fossils?) or the lower Hess (which is not well known faunally). The Hess section I saw in the afternoon needs to be restudied in greater detail. The massive cliff former in the hill is probably all Hess, but King reports some Wolfcamp and so the face of the hill needs to be studied.
