Its topography defies verbal description, but may be included under a few 

 general types. The greater part of the area may be designated as crumpled. 

 The ridges have no particular direction, their tops are broad and slopes 

 gentle, yet there is very little level ground. This type passes by insensible 

 gradations into the corrugated, in which tbe ridges are steeper, sharper 

 and arranged in somewhat parallel lines. Similar features much exag- 

 gerated produce what may be called gouged or chasmed regions. The sur- 

 face is entirely occupied by deep, irregular, elongated valleys with narrow, 

 sharp, winding ridges between, all in indescribable confusion, and every- 

 where ponds and swamps, marshes and lakes." The greater part of the 

 lakes of Indiana are in this moraine. The Pigeon, Fawn, and Elkhart 

 rivers drain a large section of this moraine into the St. Joseph of Lake 

 Michigan. Cedar Creek drains a small portion into the St. Joseph of Lake 

 Erie ; while the Eel and Tippecanoe rivers drain the balance into the 

 Wabash. 



CRANE LAKE. 

 Crane Lake, 30 to 35 acres in extent, lies mainly in the N. E. *4 of 

 Section 33, Town 33 north, Range 9 east, Noble County, Ind. It is nearly 

 a half mile long from N. E. to S. W. and about 40 rods wide. It is sur- 

 rounded by marsh and swamp on all sides. Its chief tributary is a little 

 stream about a mile long from the northeast, which drains the W. y 2 of 

 Section 27. Its outlet is by a ditch across a swamp westerly about % of a 

 mile into Big Lake. The banks and surrounding regions are not more 

 than ten feet above the water of the lake and before ditching they were 

 probably not more than four feet above the water. The bottom is of soft 

 mud and the slopes of the bed are rather abrupt, except in the southwest. 

 Soundings at intervals of about 100 feet, commencing on the northeast, 

 were as follows: 50 feet out, 15 feet deep; 150 feet out, 19 feet; then 

 15, 20, 24, 26, 32, 32, 30, 23, 26, 20, 19, 19, 19, 18, 17, 15, 10, 10, 10, 

 10, 10 feet, and 1 foot in the outlet ditch. 



CROOKED LAKE. 



The eastern extremity of Crooked Lake is in the southeast corner of 

 the N. E. % Section 3, T. 32 N., Whitley County, Ind. It extends north- 

 westerly about 1% miles into the S. E. 14 Section 33, Noble County, and 

 has an area of about 300 acres. A ridge about % mile wide and 18 feet 

 high divides the east end of Crooked Lake from Cedar Lake which drains 

 into Eel River. About the northern part of the lake there is considerable
