WHITE COUNTY. 225 
Round Mountain is easy of access either from Beebe or Conway, 
Cypress Valley being well disposed for the location of a railway line. 
Cypress Valley, especially the country about Round Mountain, 
abounds in good brick clays, while the region is well timbered. 
There are other shale hills in the Cypress Valley syncline, the 
largest of which is about 7 miles east of Conway, Faulkner County, 
in sees. 11 and 14, T. 5 N., R. 12 W., in a hill which is also known as 
Round Mountain. The body of the hill is of dark argillaceous shale 
capped by sandstone. The rocks are identical in age and character 
with those of the White County section, except that thus far no coal 
beds have been found in the Faulkner County hill. This hill rises 
between 250 and 300 feet above the valley and is nearly a mile long. 
In sees. 11 and 14 of the same township and range there is another 
shale hill that is identical in structure and character with the one just 
mentioned, though somewhat smaller and only about half a mile long. 
CLAY DEPOSITS. 
CLAY SHALES. 
In addition to the localities specified above as containing large 
and accessible clay shale deposits, it should be remembered that the 
parallel valleys of White, Faulkner, and Conway counties are, for the 
most part, underlain by clay shales, many of which are available as 
refractory materials for various uses. 
In the highlands the brick clays are most abundant in the shale 
valleys. The valley lying just northwest of Searcy and swinging 
north and northeast in the vicinity of Center Hill and opening into 
the Red River Valley east of Mount Pisgah may be taken as typical 
of those shale valleys of the county in which considerable deposits of 
brick clays have accumulated. In places these clays are spread out 
in thin beds for miles over the valley, in others the beds are from 10 
to 20 feet thick, while in still other small areas they are entirely 
absent. 
Along some of the larger streams, such as Red River, Big Indian 
Creek, and Bayou des Arcs, the bottom lands are largely buckshot 
clay with alluvial soil adjacent to the streams. In the immediate 
valley of Cypress Bayou good brick clays are abundant, especially 
about the headwaters of that stream and in the vicinity of Round 
Mountain, in T. 5 N., R. 10 W. 
In the region of the lower hills the brick clays are at many places 
of great thickness. The following is a section of a well bored near 
Pangburn post-office, in the northwest corner of the county, in the 
NE. J NE. } sec, 10, T. 9 N., R. 8 W. This record was kindly fur- 
nished by Dr. F. L. Shaw, of Pangburn.
