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

 other channel extends I'roni the top of the divide .Inst north of the Abel 

 schoolhonse Avest to the limestone ridge that is half suTimerged beneath 

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

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

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

 is now tilled with glacial sand, is at least twenty-five I'eet 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 AVhite River and compelled it 

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

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

 the old 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. 



There 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 luick their respective channels until they have cut 

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

 are Canada and Hnlil>ard's gaps. These two ga]is are both on the divide 

 betAveeu "White River and l'.e;in I'.hissom Cri'ck. They were both in 

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

 In each i-ested the foot of the ice-sheet, and through each was carried 

 south into the Bean Blossom Valley large (luautities 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 noAV as they furnish prospective 

 routes for steam and electric railways. 



Bean Blossom Creek. 



Bean Blossom Creek entei's Monroe County from the east a little south 

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

 to the uorthAA'est corner of Bloomington Township.* Here it changes its 

 direction to a northAA^est course. It continues in this direction until it 



"The change in the course of this creek is duo to its sheering off to the norlhwefton 

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

 follows the trend of these out-crops.
