Counties, into Iowa. Two currents of the ice-sheet, one coming 
; from the northeast, the other from the northwest, were confluent, 
_ Pushing against each other, upon an area reaching from Crystal 
_ like and Lake Minnetonka 150 miles northwesterly to the Leat 
a hills, and even farther north to the lakes at the head of the Mis- 
- Sssippi ri n area, or belt, extending thus, with a width vary- 
o a hundred miles, has a junction and overlapping 
ght from the northwest and northeast, and series 
ls, which appear to prove that this region was 
by the ice of the last glacial epoch; that the line 
f its currents was shifted in the latter part of this 
) far to the east upon a large district southeast of Stearns 
oy, bringing till from the west over that from the east; and 
that during the final melting and disappearance of the ice, prob- 
ably at times when this was interrupted by its reidvance upon 
Ey of the ground from which it had retreated, true terminal 
woss were formed upon the sides of this belt which had been 
nine po covered through most of this epoch. The inner mo- 
„ound in southern Minnesota and upon the Coteau des 
Ez f hills, and the very distinct series of morainic 
Sin Morrison county—one of which, accumulated by the ice-

kind, being terminal moraines formed at stages in the reces-
