was not advanced that far when the flat topography of Flatwoods was 

 formed. 



Having determined the advance of the ice-front, it is easy to picture 

 the fluviatile conditions that existed during the presence of this great ice 

 barrier. Streams of water, sometimes constricted and sometimes in broad 

 sheets, poured out from the ice sheets in the summer seasons, and worked 

 over the sandy debris, which the ice continually brought forward from the 

 nearby sandstone hills. This debris was made into the outwash plains 

 already mentioned as being along the headwaters of Allistons Branch and 

 McBride*s Creek. In the adjunct basin the water from the ice carried 

 material south and southeast from the region of accumulation, filling this 

 basin to the level of the narrow outlet south of section 11. The water in 

 being concentrated through this opening undoubtedly cut it down consid- 

 erably. The material in the wide terrace southeast of this opening con- 

 tains but little material foreign to the immediate vicinity, but there is an 

 abundance of limestone, chert a_nd sandstone material in the debris. 

 Where the stream has cut a fresh place in the terrace these materials are 

 shown in abundance. 



Turning to the eastern side of the region, we find conditions which 

 aided greatly in the making of the Flatwoods region as it appears today. 

 White River was within the ice limit of the glacier and was at this time 

 frozen with all of its upper tributaries, and incorporated within the glacier 

 itself. Practically all of the tributaries beyond Bean Blossom were within 

 this great ice clasp. The greater part of the Bean Blossom area, however, 

 was free to gather its waters before the ice-front in the summer seasons 

 at least. But the outlet and a few miles of the lower portion of this 

 stream were within the ice limit. Consequently a lake gathered before the 

 ice-front, both from the melting ice and the drainage of Bean Blossom 

 basin. The water soon reached the height of the lowest point in the 

 divide between Bean Blossom and Jacks Defeat Creek. This seems to have 

 been about one and a half miles southeast of Stinesville, near the middle 

 of sections 21 and 22, T. 10 N., R. 2 W, on the farm of Jack Litten. Here 

 occurs a col nearly one-fourth mile wide, which comes down at least 100 

 feet below the height of the divide south of this place. The elevation of 

 the col is 715 feet. Locally this col is known as the '•Valley." Since it is 

 on the farm of Mr. Litten, the writer proposes to call it the Litten Col. 



The water on passing through the Litten Col came into Jacks Defeat 

 valley, but again it had to lodge against the ice wall until it had found an
