HUBBARD AND CRONEIS 
grains rounded and some of the cavities are quartz filled. A 
few red sandstone layers. The shale is fissile, thin bedded and 
weak. Fossils found but badly mashed. 7 feet. 
11. Strong sandstone layers, one to six inches thick, gray, 
reddish and mottled. Weathers a dark red and rusty. Layers 
are even and continuous. Very thin, sandy shale partings. 
Pelecypods. 2 feet. 
12. Soft, shaly sandstone in thin beds, weathering easily 
into clayey sands. Dark gray, yellowish and brown. Brachiopods. 
2 feet. 
13. Ripple maker. Resistant gray quartzitic sandstone with 
pink lines and gray mottling, heavy and cross bedded. Heavy 
pebbles in a fine grained matrix and resembles conglomeratic 
layers of the Clinch. Cavities of considerable size are more or 
less filled with chalcedony and quartz crystals. No fossils seen. 
91/2 feet. 
14. Covered interval of soft shaly material. 38 feet. 
Near the base were found Tentaculites minutus, and Tellun- 
omya lata. 
15. Layers of purple and red, quartzitic sandstone. Fine 
bedding lines of alternate light and dark red often are apparent. 
Two to six inch layers grading off thinner and weaker toward the 
top. Weathers a rusty bronze. . 71/2 feet. 
16. Three to six layers of dense, hard red to purple quartzitic 
sandstone, even bedded and fine grained. Some of the layers 
split up on weathering into two or three layers. Would make a 
handsome building stone as it weathers a beautiful bronze. 
There is one greenish layer. 31/2 feet. 
17. Between fifty and seventy layers of slightly argillaceous 
sandstone and quartzitic sandstone, becoming thinner and 
weaker towards the bottom. 2 feet. 
18. Strong quartzitic sandstone beds two to eighteen inches 
in thickness and slightly crackled and broken. Gray, greenish 
and red in streaks. Weathers rusty, reddish and rough. Five 
feet from the top is a layer of loose material, caused by the 
weathering and leaching of a more porous layer. Ocherous sands 
in some places ; in others apparently concretionary. It probably 
is not concretionary but is a residual structure brought out by 
weathering. Corals near the bottom. 15 feet.
