QUATERNARY FORMATIONS THE DRIFT.

but few other fossils. Nothing that could be mistaken for it by a 

 careful observer has yet been found elsewhere in the state. In the 

 Kettle Range, southwest of Burlington, large quantities of this rock 

 are found, and at heights very considerably above the present surface 

 of the rock. The blocks are usually somewhat worn, but still sub- 

 angular. Their identity is put beyond question by the presence of 

 Illcenus imperator. 



Passing northward along the Eange, in the town of Whitewater, 

 there appear large masses of the subjacent Galena limestone, distrib- 

 uted upon and through the drift, being found at from 150 to 175 feet 

 above the bed rock in the vicinity. These erratics are frequently 

 very little worn, and in one case a stratified mass that seemed to have 

 been bodily transported was found at least 100 feet above the bed 

 rock. Metamorphic and igneous erratics occur in great abundance 

 and variety here. 



Section cf the Kettle Eange on the line of the C., P. & L. S, R. R., southeast of Whitewater. The 

 figures show the elevation above Lake Michigan. The north ridge is composed of exceedingly 

 coarse, mixed material. 



In the towns of Palmyra and Eagle where the Kange crosses the 

 Cincinnati group, large quantities of the peculiar areno-argillaceous 

 and calcareous shales, belonging to the lower portion of that forma- 

 tion, and which on the east side of Lake Wmnebago lie at from 175 

 to 200 feet below the upper face of the group, are found in the ridges 

 of the Range. It is a soft rock that could not resist much abrasive 

 action, and yet it predominates in some of the ridges over all other 

 forms. It contains an abundance of small linguloid fossils, rendering 

 its identification beyond question. Although so abundant here, these 

 bowlders are found but very rarely except for six or eight miles along 

 the Range where it crosses the formation from which they were evi- 

 dently derived. They are most abundant in the ridges on the west 



side of the Range.
