ill line with the mound to the north and being composed of the same kind 

 of material suggests that the two were once continuous and are yet con- 

 tinuous beneath the valley floor. 



South of Bean Blossom Creek, opposite the railroad cut in section 9 

 of the saiiie township, there is another ridge standing in line with the 

 projecting "mainland" cast of Jack's Defeat Creek. It is almost a third 

 of a mile in length, aliout 400 yards wide and some 80 feet above the 

 valley floor. It seems to have been a ridge between Jack's Defeat and 

 Bean Blossom creeks before the aggrading of the valley floor caused the 

 former creek to change its channel to the east through a former wind 

 gap in the ridge. This left the ridge isolated. 



North of the Bean Blossom, in section 24 of this same township, there 

 is another consiiicuous ridge known a'< "Lost Ridge.'" It is in line with 

 the "main land" to the north, from which it is separated by only about 

 a hundred yards of flat floor, through which a small stream runs from 

 the Bean Blossom Valley to .ioin Indian Creek. In this case, as in the 

 previous one. the trend of the slope and the trend of the adjacent valley 

 slope, together Avith the fact that the composition of the rocks is identical, 

 suggest attachment beneath the present valley floor. There are several 

 other similar islands in the Bean Blossom Valley. 



These lilts of relief are "islands" surrounded by alluvial material. 

 They strongly attest that the Bean Blossom Valley has been aggraded 

 very considerably. 



Half Stjbmeeged Points and Peninsulas. 



.Several tied-on. peninsula-like ridges, known as knobs and points, pro- 

 ject from the valley walls into the valley of Bean Blossom Creek, -with 

 the connecting neck almost submerged beneath the alluvium of the vallej*. 

 They also attest to the aggrading of the valley. 



Abandoned A' alleys. 



In tlie glacial region on the south side of Bean Blossom Creek several 

 of the short valleys that were fllled with glacial debris still remain fllled. 

 The glacial fllling of the other valleys have been removed wholly ci- in 

 liart. Those Avhich remain fllled have had no springs at their heads since 

 glacial times. Since mucli of the drainage of that part of the county is 

 underground drainage the little valleys have remained filled.
