South Bend, Indiana, is a most interesting locality with reference to 
the glacial period in Geology. It is here that three great lobes of ice 
terminated, viz: the Lake Michigan Lobe, the Saginaw Lobe and the Erie 
 Lobe; and for this reason, we find here rock material mingled from three 
very far removed localities. 
The northern edge of the Erie Lobe piled up the moraines represented 
by the hills which run parallel with the St. Joseph River between South 
Bend and Mishawak 
Lake Michigan Lobe piled up the hills lying to the west of the 
St. Joseph River. They may be seen best near Bertrand on the Indiana- - 
Mi otre Dame; 
these hills can be traced southwards as far as a point west of St. Mary's s 
Academy, one mile west of the University. 
Different kinds of soil may be found within a radius of a few miles
