Behind the town of Landisburg the following section can

The slabs in one of these beds of the Bloomfield sandstone 

 are completely covered with the casts of Leper ditia alta. 



The Gray shales lie between the top of the section here 

 represented and the limestone which crops out on the side 

 of the hill. They are apparently about 200 feet thick as 

 usual, but their summit is not well exposed. 



The great extent of the outcrop of the Bloomsburg red, 

 shale gives to this township its fertile soil. It is the most 

 easterly of the townships of Perry county which can boast 

 thai the greater part of its surface consists of good farming 

 hind. The shale ground extends over all the northern and 

 middle parts of the township and high up the slopes of the 

 mountains, running deep into the long valleys which form 

 sheltered nooks secluded from the rest of the world, the 

 southward sloping sides of which should produce as early 

 crops as any places in the county.
