Conclusion 



This study has attempted to show that this case of stream 

 diversion is due to a combination of causes: first, that of land warp- 

 ing which induced the piracy of part B by the Rocky Fork, push- 

 ing the divide back to a position representing approximately the 

 former level of the swamp which occupied part C; second, that the 

 glacier, first by drift deposits left in part C, and later by con- 

 structing a drift barrier across its southern end, ponded the 

 stream which flowed into the Licking, and, through outwash 

 deposits, formed a swampy condition, eventually reversing the 

 direction of flow, and adding that stream also to the present 

 Rocky Fork.
