Strata apparently referable to the Yarmouth Interglacial interval are found 

 in various parts of Indiana. Near South Milan, Ripley County, a section is 

 reported showing the strata indicated below: 109 



1. Light colored clay soil 10-14 feet 



2. Yellow clay with flint gravel and fossil corals (Illinoian) 12 ' 



3. Blue glacial clay (Illinoian) 12 " 



4. Coarse yellow sand with recent shells and water (Yarmouth) 8 " 



5. Blue clay, muck, containing roots and limbs of trees (Yarmouth) 8 " 



These strata are in an old river valley, probably preglacial. 



In Vermilion County 110 wells sunk in the prairie between Eugene and Perry- 

 ville reach a mass of leaves, twigs and trunks of trees, locally known as "Noah's 

 barn-yard. " The deposit is soft, sticky, bluish clay, 6-10 feet thick, and over- 

 laid by 60 feet of "alluvial sand. " The deposit is believed to be referable to 

 the Yarmouth horizon.
