372 J. J. Stevenson—Fox Hills Group of Colorado. 
Certainly very different from anything exposed on the western 
side of the river. The rocks here are almost horizontal, but 
vans, I followed up the gulch from this boring to No. 2, 
which is but a short distance from the last and only a few feet 
higher. Between the two is a blossom of coal or carbonaceous 
shale. Almost immediately north from the gulch and at 
barely 100 feet above No. 1, a third boring was put down, 
in which the following section was obtained :

_ The black shale, No. 5, is very carbonaceous throughout, and 
o. 10 is in close proximity to the dark shale or coa/ seen 
between borings No. 1 and No. 2, which rests almost directly 
on the sandstone at the top of the section in No. 1. 
At fourteen feet above the curb of this boring, a shaft was 
inchura. Fragments of these were seen on the dump, and 
some good specimens of the univalves were obtained. |
