1) Conglomerate brown chert and quartzite dominate (1/2-1") brown cement, a
few dark limestone cobbles 3". 0'SW - 15'+NE, 25' on hill side.
2) Covered, probably light brown silty shale - 12'.
3) Sandstone, orange-brown, silicified in part. A few fossil molds - (?) - 3".
PG. 157
4) Siltstone, mudstone and shale, interbedded very sandy, gray to greenish-
yellow color. 22'.
5) Like 3, with 1/4" beds and crinoid columnals - 3".
6) like 4, 2'.
7) like 5 (collection 9.2.58.5) 4". Contains "Decie Wolfcamp" fusuline fauna in
part.
8) like 4, 10'.
9) Sandstone, medium to light brown 8" some conglomerate pebbles.
10) Sandy siltstones and shales, some limonitic stained bands of ss (very fine
grained). 41'.
11) Sandstone, light orange weathering, no internal lamination; total - 1.5'.
12) Sandstone, light tan, friable, some silty horizons - 2" to 8" beds - 20'.
PG. 158
13) Covered (here), continuation of bed 12 as seen in next gully north - 14'.

Iron Mt. Ranch
North end of Lenox Hills
Dimple, Tenus and upper Caballos are repeated several times here. The highest
of the beds are less than 250' from top of this last crest. Beneath the massive
limestone (75-80' thick est.) is a marly or sandy interval at least 70' thick, about
another 70' are covered, then the folded Penn beds.
Most, if not all, of Sect. 43 is missing 3/4 mile SW of where that Section was
measured. Unit 14 (Sec. 43) rests on the brown limestone on the Dimple in a
couple of low hills.

1) Limestone, dark gray to black, fusulines Triticites, echinoid spines, crinoid

2) Limestone medium gray to brown - changes to shaly strike, massive,
sparingly fossiliferous - dips south 5°. 17'.
