rarely being a pure sandstone. Extensive quarries of valuable 
flagstones have been opened up in many places, the most no- 
table being in the vicinity of Farlington, Bandera, Gilfillan, 
Redfield and Pawnee. Their arenaceous character is observ- 
able farther west where reached by the drill, and a number of 
excellent gas-wells and oil-wells obtain their product from the 
sandstones in the Bandera shales. In places their change 
from sandstones to clay shales is very rapid and hence re- 
markable. They also carry considerable coal, which in places 
becomes workable, such as the coal-mines near Hammond, 
Fulton and Prescott, that have been worked to a considerable 
extent. 
Altamont Limestone.16 
The name Altamont limestone is here applied to the lime- 
stone at Altamont, the schoolhouse at that place being built 
immediately on top of it. This name was first used by Adams 
in volume I of this series of reports. It is also described by 
Bennett!” in volume I of these same reports, being spoken of 
as the “8-foot system” lying within the Pleasanton shales, 
showing that at that time it was sufficiently TEESE to be 
recognized as dividing the Pleasanton shales. 
Later, Adams!® withdrew the name Altamont and substi- 
tuted the name Parsons for the same formation. In his later 
description he speaks of it as consisting of two members. 
Subsequent work by this Survey has shown conclusively that 
he was in error, and that the upper limestone is the one so 
prominent at Coffeyville which is designated the Coffeyville 
limestone later in this volume. Why he should have changed 
the name Altamont to Parsons with no apparent reason is en- 
tirely unknown. As Altamont has already appeared in vol- 
ume I of this series of reports, of course we are under the 
necessity of retaining the name, and this is particularly desir- 
able on account of its eminent appropriateness. 
Thickness.—The Altamont limestone is nowhere more than 
10 feet thick, from which it decreases in places to a thickness 
of from 3 to 4 feet. 
Area.—The Altamont limestone occupies a zone extending 
from the south side of the state opposite Altamont northeast- 
ward to the east side of the state in the vicinity of Pleasanton.
