Description
In the northwest part of the State, east of the Pecos, the
formations lie nearly horizontal. This structure prevails
over the entire Plains, extendingfrom the north end of the
Panhandle to a line joining San Angelo and Pecos on the
south. This area measures 330 miles from north to south
and 170 miles from east to west. The deeper lying rocks
can hence be known here only from inferences based on their
appearancein distant outcrops outside of this area and from
such local observations as maybeobtained fromdeep explorations.
It is singularly fortunate for our knowledgeof the
stratigraphy of this part of the continent that a deepboring
was made at a point not far from the central part of the
area denned. The exploration enables us to know by
actual observation what strata underlie. It will enable us
to say with greater accuracy what other borings will penetrate
even at considerable distances from this exploration.
It furnishes firsthand information on the stratigraphy of
this part of the State. While this paper describes the
section of a single boring,it really gives the only facts so far
known concerning the deep stratigraphy of a region covering
one-fifth of the area of this State.
