lost ridge just east of the railroad, has already been mentioned. The 

 other channel extends from the top of the divide just north of the Abel 

 schoolhouse west to the limestone ridge that is half submerged beneath 

 the sand just east of the railroad track in section 5, Bean Blossom Town- 

 ship. It is about a mile in width and extends from the Bean Blossom 

 Valley north to the White River Valley. The bed of this channel, which 

 is noAv filled with glacial sand, is at least twenty-five feet below the 

 present surface, as is attested by the sections taken in the wells of the 

 region. The origin of this channel is still undetermined. The data at 

 hand seem to suggest that after the retreat of the ice-sheet from the 

 immediate vicinity, an ice-gorge dammed White River and compelled It 

 to cut a new channel. After the breaking of the ice dam the river, as the 

 new channel was not as deep as the old, abandoned the new and resumed 

 the okl channel. As it was being abandoned the new channel became a 

 slack water region in which was deposited the sand which now fills it. 



Wind Gaps. 



Tliere are many wind gaps in the area. They are the result of the 

 degrading action of small streams on opposite sides of a divide. The 

 streams have etched back their respective channels until they have cut 

 through the divide, thus forming a wind gap. Conspicuous among these 

 are Canada and Hubbard's gaps. These two gaps are both on the divide 

 between White River and Bean Blossom Creek. They were both in 

 existence in glacial times as they have glacial material deposited in them. 

 In each rested the foot of the ice-sheet, and througli each was carried 

 south into the Bean Blossom Valley large quantities of glacial debris 

 as has been shown in the discussion of the deltas of Indian and Honey 

 creeks; the latter creek heading in Hubbard's Gap and the former in 

 Canada Gap. These gaps are in interest now as they furnish prospective 

 routes for steam and electric railways. 



Beax Blossom Creek. 



Bean Blossom Creek enters ^lonroe County from the east a little south 

 of the northeast corner of the county and flows a little south of west 

 to the northwest corner of Bloomington Township.* Here it changes its 



direction to a northwest course. It continues in this direction imtil it 



• 



'"The change in the course of this creek is due to ito sheering off to the northwest on 

 coming in contact with the harder Harrodsburg and Salem limestoDcs. Its lower course 

 follows the trend of these out-crops.
