movemeut the evidence of obstruction and readjustment appears. Near 

 the southern limit of the drift the Patolia River is an example of a stream 

 made up of several sections. Three northwestward flowing sti'eams 

 were obstinicted in their lower courses by the ice, and compelled to seek 

 westward outlets across divides along the ice border. The lower course 

 of White River was also obstructed and the part within the unglaciated 

 area ponded up in its deep valley through the Knobstone. In the main 

 stream and in many of its tributaries temporary lakes were formed which 

 overflowed over the ice or along the ice border. 



West White River is conspicuously a border drainage line as far up 

 as northern Monroe County, as shown in its course through Owen, Greene 

 and Daviess counties. 



The position of the Shelbyville moraine indicates that Raccoon Creek 

 was in existence through half its length before the Wabash was uncov- 

 ered north of Vigo County. Further recession northward brought Sugar 

 Creek into existence. This stream is very distinctly of border drainage 

 type, as shown by the prominent moraine along its north bank from its 

 mouth to southwestern Clinton County. After further recession of the 

 ice sheet Coal Creek took its way north of a region of morainic uplands, 

 until it came against a strong north and south moraine which deflected 

 its north branch in a great bend, remarkably like that of the Wabash. 

 The part of this stream above its great bend is comparatively meander- 

 ing and its valley, which is very shallow, is in marked contrast with the 

 deep, broad valley below the bend. South Shawnee Creek runs west 

 parallel with North Coal Creek and bends to the north within a mile of 

 where this creek bends to the south. A broad, marshy valley connects 

 the two bends, indicating that South Shawnee Creek formerly turned 

 south. These creeks have their sources at the crest of the kame moraine, 

 which runs northwest from Darlington, Montgomery County, toward 

 Independence, Warren County, and are guided by moraines trending east 

 and west. To the east of the Darlington-Independence divide, the streams 

 flow northeast in a direction opposite to that of the Wabash. They are 

 turned northwest into that stream by a moraine running southeast from 

 a point about five miles south of Lafayette to the southeast corner of 

 Tippecanoe County. The three forks of Wild Cat Creek coming from the 

 east turn north along the western side of a moraine, which lies along 

 the western edge of a till plain rapidly rising to the east. This moraine, 

 in my opinion, is the strong outer moraine of the Erie lobe and marks
