Two roads only pass over it where it has its full height, one 

 leading from New Germantown into the Horse valley and 

 the other westward over the bend in the range to Concord. 

 Both are rough, stony roads but are much traveled, being 

 the only paths from the west end of Perry into Franklin 

 and Juniata counties. Conecocheague mountain at its 

 eastern end is a complete arch, but divides in Jackson 

 township and from that point to its western termination is 

 a monoclinal south-dipping range. 



Immediately on leaving Perry county the ridge turns 

 sharply, reenters the county and forms Round Top which 

 commands the head of Sherman valley and is a conspicuous 

 object for many miles. The northeastward course is short ; 

 for, zigzagging again it passes over the county line to the 

 southwest, with a southeast dip, and continues for about 

 twelve miles as a straight synclinal range (Dividing mount- 

 ain) between Path valley and Amberson valley. 



Returning from its long excursion into Franklin county 

 the Medina sandstone again enters Perry and forms the 

 high, broad, stony ridge called Rising mountain to the 

 southwest of New Germantown. The arch of this anticline 

 gradually sinks until the sandstone disappears from view 

 below the surface and is followed by other beds forming 

 the range known as Buck hills. 



The southern side of the arch of Rising mountain after 

 it has been divided to the southwest over the axis is con- 

 tinued into Franklin county where it becomes synclinal by 

 meeting the northern side of the next fold. 



It again returns northeastward with a northwestern dip 

 and arching over another anticline forms Amberson ridge. 



Sinking to the northeastward, as Rising mountain sank, 

 the anticline rises in the opposite direction, is divided over 

 the axis and the southwestern limb dipping to the southeast 

 meets the north side of the great fold of Bower mountain 

 and rises as a syncline into the air, forming a high knob 

 overlooking Amberson valley. 



Thus far we have three anticlines projecting themselves 

 into Perry county and forming East Round Top, Rising 

 mountain, and Amberson ridge. There are four corre-
