WEST VIRGINIA GEOLOGICAL SURVEY. 45 



river and creek bottoms, and also by Pleistocene river terrace 

 deposits occurring at higher levels along the valleys of the 

 West Fork and Little Kanawha Rivers and some of their trib- 

 utaries. These terrace deposits have been described in Chap- 

 ter II. 



The Permo-Carboniferous rocks, or Dunkard Series, as 

 indicated on Map II, cap the ridges of northwestern Lewis and 

 are present also in the Grassland and Roanoke Synclines 

 through the center of the county, and in Gilmer they cover the 

 high summits generally throughout the county. 



The rocks of the Pennsylvanian Period, however, consti- 

 tute the great bulk of surface formations. The upper four 

 series; viz, the Monongahela, Conemaugh, Allegheny and 

 Pottsville, crop to the surface successively from the north- 

 western to southeastern part of the territory of this Report. 

 The Allegheny and Pottsville are found only in the southern 

 panhandle of Lewis. 



Numerous geologic sections, consisting usually of careful 

 hand level surface measurements combined with the records of 

 oil and gas and coal test borings, and showing the stratigraphic 

 succession from the Permo-Carboniferous to the Devonian, 

 will be given in the following pages. 



LEWIS COUNTY SECTIONS. 



Hackers Creek District. 



In the following section, arranged in descending order, the 

 surface portion was measured with hand level up a hill three- 

 fourths mile southeast of McWhorter, at the Harrison-Lewis 

 Line. The lower portion is the record of the E. S. McWhorter 

 No. 907 (11) gas well, drilled by the Hope Natural Gas Com-
