the sandstones — stand out now as chills and ridges, while eroding 
agencies have scored valleys in the softer and more easily affected 
rocks — that is, the shales. As the rocks of this region are alternate 
sandstones and shales, the topographic result of this condition and 
action is a series of parallel valleys and ridges, running, as a rule, 
east and west across the county. 
As a rule the axes of these rock folds are not horizontal but are a 
little lower at one end than at the other. From this dipping of the

folds it results that the ridges, instead of being everywhere straight, 
curve around and cross the lower ends of the axes of the folds. This 
will be understood by reference to the accompanying diagram (fig. 7). 
It will be understood from this also that the valley aeb is one

and the same bed would dip southward on the south side of the axis 
of the fold. 
Fig. 8 is an east-west section along the summit of Meto Mountain 
(a group of parallel ridges about 5 miles wide lying just north of 
Faulkner Gap) and across the summit of Round Mountain to 
Arkansas River. 
A north-south section across the Meto Hills to a point about 3 
miles north of the town of Holland is given in Fig. 9.
