100 yards to the east the 8,9 and most of the 7 beds are gouged out and a chert-quartzite conglomerate fills a 40 to 45' depth channel. I take this to be an old river channel. It has the appearance of the typical Wolfcamp conglomerate of the western part of the basin. This channel is about 130 yards wide in outcrop.
12) Dolostone, brown weathering, 6" to 1' beds, locality the beds are unaltered limestone. 36', 8/19/57/3.
13) Sandstone; light brown to tan weathering, zones of chert and quartzite conglomerate pebbles. 3" to 1' beds, 6'.
14) Conglomerate; 8" boulder, beds are very anticular with sandstone lenses 0-1'; mostly chert and quartzite near base, becomes limestone near top: 16'; this is like conglomerate in stream channel; little or no limestone for most part.
15) Covered, 15' red soil.

16) Conglomerate; mostly dark gray limestone pebbles, some chert and quartzite pebbles; Sandy and clay matrix is red. (mostly a pebble conglomerate) 2'.
17) Covered, 18', red soil.
18) Calcarudite, light gray weathering, 2' to 8' beds, 36', 12" cobbles.
19) Covered, red soil, 12'.
20) Calcarudite; 8', 10" cobbles, light to medium gray weathering.
Top of Hess basal Conglomerate Unit
I would draw the top of the Wolfcamp (basal on lithology) at the top of the dolostone unit, and the base of the Wolfcamp at the base of Unit 7. The 2' conglomerate (#11) is hard to explain but it seemed to have only limestone of the 7,8,9 types in it. The rest of the conglomerates had a great deal of cherts. {note: illustration followed}

Section 32, west side of Canyon (Road to high pastures) dip NNW 23°.
Covered below.
1) Limestone, dark gray with layer and irregular patches of orange-brown sandstone. Brach shell frags. 1' to 2' beds; 14'. 8/20/57/1. (=#5 limestone in Gaptank of King)?
2) Covered, 37': mostly greenish-gray shale. Collection 8/20/57/9.
3) Sandstone, orange-brown weathering; 8" to 1' thick; well-sorted, very fine to fine sand sizes. Well cemented (Fe2O3 and Silica?); 1'.
4) Covered, 52', a few feet of shale poorly exposed at base.
5) Calcarudite, dark limestone cobbles up to 4" in diameter, Reddish to orangish-brown sand matrix well-cemented; at least 4' thick, base is covered under #4.
8/20/57/2. Many fusulines in matrix.
