Smaller anticline inliers may sometimes be also observed in the 

 plateau regions of the central part of the State where a series of 

 gentle folds representing further extension of the Appalachian 

 mountain folding have been traced by Kindle. 1 Occasionally a 

 small inlier will even bring out the presence of a fold in a region 

 where there seem to be no indications of folding at all. Thus the 

 writer observed a small Lowville limestone inlier coming up from 

 Lake Ontario at Three Mile bay (Clayton quadrangle, N. Y.). 



This [see text fig. 9, inlier 1] 

 follows first the brook, but 

 about 34 of a mile above its 

 month, it leaves the brook 

 and rises upon the hillside, 

 ending just east of the Three 

 Mile Bay railroad station. 

 Here, in a quarry, the arch 

 of the fold is exposed in the 

 Lowville limestone beds, with 

 the Black River on the flanks. 



In the arid regions of the 

 AVest, where neither drift nor 

 alluvial deposits obscure the 

 outlines of inliers, the inti- 

 mate relations of mliers and 

 folds are much clearer shown 

 and forms of bizarre outline 

 produced by atmospheric
