was hot 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 Alliston’s 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 and 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
