12. INDIANA 

 BY WILL SCOTT 



I. GENERAL CONDITIONS 



1. Topography 



The southern two-fifths of Indiana 

 was slightly affected by glaciation and 

 the northern three-fifths was covered 

 with the Wisconsin ice sheet. The 

 unglaciated portion is divided into 

 seven physiographic regions whose boun- 

 daries run approximately north and 

 south. Beginning with the east the 

 names of these regions and their areas 

 in sq. mi. are: Dearborn upland, 1925; 

 Muscatatuck slope, 1875; Scottsburg 

 lowland, 950; Norman upland, 2075; 

 Mitchell plain, 1125; Crawford upland, 

 2900; and the Wabash lowland, 4900. 

 Their names indicate the relative 

 elevations; the Dearborn upland is 

 about 1000 ft. above sea level; the 

 Wabash lowland is near 500 ft. The 

 Mitchell plain is the sink hole region of 

 the state. It together with the eastern 

 part of the Crawford plain, is the cave 

 region containing Wyandotte, Maren^o, 

 Shawnee and other less notable caverns. 



The Tipton till plain is a ground 

 moraine with little variety in topog- 

 raphy. It occupies the southern half 

 of the glaciated area in the morainal 

 and lake region. This consists of a 

 small lacustrine area near Fort Wayne, 

 and the Michigan lacustrine area, the 

 Kankakee lacustrine area, the Val- 

 paraiso moraine and the Huron-Erie 

 Saginaw interlobate moraine. The 

 Michigan lacustrine area west of Gary 

 consists of several parallel ridges which 

 mark successive beaches of Lake Michi-
