10) Limestone, blue-gray, sort of rubble, but almost a calcarudite. Darker
"pebbles" are in a lighter matrix, but the difference seems to be one is reticular
around the other, not good pebbles. 22', 1" to 8" beds 7/10/57/11.
[burrowed??] [weathered??]

{note: illustration:
bed 10: 7/10/57/11
bed 13: 7/10/57/8
bed 17: 7/10/57/12
bed 19: 7/10/57/13}
11) Limestone, light gray weathering, massive, fine grained, 11'.
12) Limestone, shell hash, weathered mottled gray and brown, crinoids,
bryozoans, a few brachs, 1/4" to 6" beds. A few inches of shale at the base of
this unit. Top of unit has brown weathering color characteristic of the middle an
upper Wolfcamp cycles. 15'.
13) Shales in lower part (5' to 7'), becoming more silty and sandy, fusulinid
sandstones in upper 2' to 3', 1' shell hash. Collection 7/10/57/8 see note on
picture p. 79, 18'.

Between unit 12 and 13 slicken-side surfaces were seen cutting the down dip
exposures of bed 12, no major displacement has taken place, but this seem
rather to be the adjustment to a slight Post Hess warping forming a gentle
syncline near the tank.
14) Calcarenite, yellow to orange-brown weathering quite quartz, rich and might
be best considered as a quartz sandstone. 2.5'.
15) Cycle -
a) 4' gray shale
b) 1' like #4 below (at top)
16) Gray shale 9'.
17) Sandstone yellow weathering, 1' beds on less; 16' The fine sandstones have
a great deal up to 40 or 50% fusulines, crinoids, gastropods, 7/10/57/12.
18) Covered, probably continuation of 17. [15'?]
19) Limestone, weathers gray to brownish-gray, shell hash, brachs, some
fusulines. [12'?] 7/10/57/13.

20) like #19, 7'.
21) Sandstone, very fine high CaCO3 4' greenish-yellow.
22) like #19, 21'; changes to dolomite along outcrop (100').
Although no Conglomerate beds were found, I believe beds 19-22 are in the
same interval as the "Hess" Conglomerate of section 10. [probably a matter of
pre-Hess topographic relief.]
