outlet. This was found just northwest of Ellettsville through the deep 

 col, which has been described as the southeastern opening of the Flat- 

 woods region. This opening shall be henceforth called the Ellettsville Col. 

 The water however was not confined to this col alone ; it came over the 

 divide to the north, especially through the region where a small stream 

 leads from the extreme southwest corner of section 33, T. 10 N., R. 2 W. 

 This brought the water coming from the Bean Blossom region and also that 

 coming from the melting ice into the Flatwoods region. In the first part 

 of this paper it was mentioned that the slope of the eastern Flatwoods 

 region was very gentle from the periphery, and that the deposits extended 

 much higher at this side of the basin than anywhere else. These features, 

 along with the presence of geode fragments in Raccoon Creek valley, were 

 instrumental in the investigation of the possibility of the entrance of the 

 Bean Blossom waters. 



After entering the Flatwoods region an outlet for the inflowing 

 waters, mingling with that which was coming from the western ice-front, 

 was found through the opening near the Owen-Monroe County line in 

 section 1. This outlet, which might be designated as the Raccoon Creek 

 Col, has already been described. But again the waters were to be checked 

 by the ice-front in the Raccoon Creek Valley near Freeman. There must 

 have been an outlet, either under the ice or around it, in the vicinity of 

 Freeman near the 700-foot contour line; but such an outlet was not dis- 

 covered. The terraces come to that height here, and slope from the above 

 regions, indicating that the outlet at the time that the terrace-flat was 

 formed could not have been either higher or lower. 



Since the outlet in the Freeman vicinity was at the 700-foot contour 

 line, it is easy to see the terraces representing the old lake bottom would 

 not be any higher at this point, but that they should be higher above this 

 point. This is true, as has already been described. The terraces up Little 

 Raccoon Creek also get twenty-five or thirty feet higher in the upper 

 region, where they fade out into the recent alluvium. 



It is quite probable that for some time the waters entered Raccoon 

 Creek just south of the Reeves School through a col on the section line, 

 between sections 8 and 17, T. 9 N., R. 2 W. This col is about 770 feet in 

 elevation, and is barely above the level of the silt line on the periphery of 

 the region. During the time the water went through this col. the ice was 

 advanced far enough cast to obstruct the passage-way through the Rac- 

 coon Creek col.
