 Detailed Geology of Susquehanna County, 



1. Apolacon, in Susquehanna County. 



This township occupies the extreme northwestern corner 

 of Susquehanna, and is almost a parallelogram in shape 

 with the longer sides extending north and south. 



It is drained chiefly by Apolacon creek, which rises on its 

 eastern and northeastern border, flows northwest into the 

 State of New York near the western line of the district, and 

 keeping northward empties into the Susquehanna river. It 

 is a very sluggish stream throughout the most of its course, 

 as it is constantly bordered with banks of Drift which totally 

 cover up and conceal the bed-rock. 



Near the southern line of this area there is a low divide 

 between the head-waters of the Apolacon and those streams 

 which carry the drainage southward and southwestward 

 into the Wyalusing ; here the aspect of the country looks 

 very much as though the northern ice sheet had cut down 

 the divide to such an extent that the morainic drainage may 

 have ]^assed southward across it into the Wyalusing valley. 



The whole area of the township is so sheeted with Drift 

 that very little of its rock-structure can be seen at any point. 



This is one of the few townships in Susquehanna in which 

 the Drift is found to contain any bowlders of granite or 

 metamorphic rocks. They are all small however and much 

 water-worn, indicating transportation over a long interval. 

 No granite bowlders were observed greater than two feet in 

 diameter, and in the great majority of instances they do 

 not exceed one foot. 



Though the bed rock is thus almost universally concealed 

 in Apolacon, yet a few of its highest ridges furnish rock
