m color, degree of coarseness, time of deposit, and cliemical 

 composition. The section in the western part of the county, in- 

 cluding the greater part of the towns of Randall and Wheat- 

 land, is the region of Kettle Range Moraine Kames. This sec- 

 tion composes the extreme southeastern part of the Kettle range. 

 This region is more undulating than any other part of the 

 county, in fact some of the hills are quite abrupt. In this same 

 region and also in the town of Salem tliere are numerous small 

 moraine lakes, which add much to the beauty of the land. The 

 most important of these lakes are Powers, Elizabeth, Mary, 

 Silver, and Camp. 



Adjoining this section to the eastward, and including the 

 eastern part of the towns of Randall and Wheatland, all of 

 Brighton and Salem, and the western part of Paris and Bris- 

 tol, is the recrion of bowlder clav. This resrion is of an earlier 

 formation than that just described and consists of a commingled 

 mass of clay, sand, gravel, and bowlders variously arranged 

 with reference to each other and spread out irregularly over the 

 surface of the limestone bed below. 



The formations of the other two sections are known as the 

 light colored pebble clay and the beach. The light colored 

 clay covers the greater part of the towns of Paris, Bristol, 

 Somers, and Pleasant Prairie. This formation is very similar 

 to the bowlder clay, and only differs from it in that the bowlders 

 are smaller and the clav is of a liirhter color. The beach forma- 

 tion covers the eastern part of the towns of Somers and Pleasant 

 Prairie, extending on an average about one mile inland from 

 the lake shore. At the surface there is a deposit of sand and 

 gravel, with a varying, but subordinate admixture of clayey and 

 marly material. The gravel averages about ten feet in thick- 

 ness, and is usually fine, and interstratified with sand and occa- 

 sionally with clay. 



The essential features of a drift foimiation of this sort are its 

 industrial value. The accumulation, deposit, powdering, and 

 commingling of a vast variety of materials by the glacial forces 

 must inevitably result in producing a sub-soil rich in variety of 

 minerals and well suited to give a secure and permanent foun- 

 dation to agricultural industries.
