MISCELLANEOUS MATERIAL. 
ROUGH STONY LAND. 
Rough stony land includes rock exposures, cliffs, and land 
which is too steep and rough to plow or cultivate profitably. It 
may be considered nonagricultural, as it is of value only for the 
small amount of timber and pasture which it supplies. 
This type occupies a large part of the steep walls bordering 
the valleys and forms a border between the valley bottoms and 
the high land of the ridges. The type is developed as narrow 
bands, many miles in extent, winding in and out of the valleys 
and coves, but confined to the steepest slopes. A part of the type 
occurs as narrow ridges upon which areas of soil too small to be 
mapped are sometimes found. The bluffs and cliffs are highest 
along the western portion of the county, and frequently reach an 
elevation of 450 to 500 feet above the valley bottoms there. The 
ridge tops are also wider here than elsewhere, and range in 
width from one-half to 1 mile, while in the interior of the county 
and along the eastern portion the valleys ramify more exten¬ 
sively, the ridge tops are narrower, and the steep valley walls 
are not so high. The elevation of the ridge tops ranges from 
150 to 250 feet above the valley floor throughout most of the 
interior of the county. 
Rough stony land is quite uniformly distributed throughout 
the upland portion of the county and is intimately associated 
with Knox silt loam and the steep phase of that type. Wherever 
there are a few inches of soil it is usually a silt loam, though there 
are exceptions to this in the region of sandstone rocks where the 
soil is sandy. The greater proportion of the rock exposed con¬ 
sists of lower Magnesian limestone, though there is also consid¬ 
erable Potsdam sandstone exposed directly below the limestone.
