130 LIFE OF THE PLEISTOCENE 



Where thickest it is somewhat calcareous in the lower portion and carries small 

 molluscan shells of land and water species, similar to those found in the Iowan 

 loess. " 



III. INDIANA 



1. Lacustrine deposits 



Records of lacustrine deposits in Indiana are exceedingly rare, that of 

 W. M. Mills 36 being the only reference observed. Near Winona Lake, Kos- 

 ciusko County, the shells of Unios and univalve mollusks have been found near 

 an ancient beach ten or more feet above the present level of the lake. The 

 shells, with vegetable remains, are on peat bogs, from one-fourth to one-half 

 mile from the present edge of the lake. The old beach in the embayment is 

 18 to 20 feet above present level. The deposit at the head of the embayment 

 is three quarters of a mile from the shore. It is thot that the lake was held 

 up by two ancient glacial dams. The species of mollusks are not given and 

 their general character can only be guessed. Indiana contains a large number 

 of lakes, many of them with marl beds, which doubtless contain large numbers 

 of mollusks referable to post- Wisconsin time. Galba galbana is in the United 

 States National Museum, received from marl deposits three-fourths of a mile 

 southwest of Stewartsville, Posey County, and one and one-half miles north- 

 west of Petersburg, Pike County. 



2. Terrestrial Deposits 



Records of terrestrial animals are numerous from Indiana, but they cannot 

 be referred to any definite lake stage, altho nearly all are post- Wisconsin. In 

 Randolph County both the mastodon 37 and Castoroides 38 have been found, the 

 latter a few miles east of Winchester and the mastodon near Losantville, in a 

 peat bog. The Castoroides was in a swamp, about eight feet below the surface, 

 in a bluish gray silt underlying four or five feet of alluvium very rich in vegetable 

 mold, and overlying drift gravel. Castoroides is also reported by the same 

 author from Greenfield, Hancock County. 39 



Wabash and Grant counties have furnished, perhaps, a larger number and 

 variety of fossils than any other county in the state. Moses and Benedict 

 have recorded the following species from Wabash County: 40 



Elephas primigenius, in Pleasant Township, under five feet of muck; also near Dora. 

 Mammiit americanum, two miles west of Laketon, in ditch on farm near Silver Creek.
