This is of terrace structure to an unl^uown distance back from the 

 river and is uot limited on the west by a perceptible bluff. At Battle 

 Ground the level of the prairie is continued south to the point Avhere the 

 river swings across the valley a.tiainst the foot of the west liluff. This 

 part of the high terrace is nowhere more than one-fourth of a mile wide. 

 The Tippecanoe battle field occupies its entire width of a few rods between 

 the lower terrace on the east and the valley of Burnett's Creek, which 

 separates it from a high bluff on the west. 



The low terrace just mentioned averages about one mile in width and 

 its border along the tiood-plain takes the form of a distinct ridge, ap- 

 parently a. sand-1)ar. higher than the general surface of the terrace. This 

 surface is ten to fifteen feet above the tlood-plain. 



Below the westAvard bend of the river the tlood-plain occupies the full 

 width of the valley separating the terrace tracts below from those above. 

 This flood-plain surrounds a detached section of Ioav terrace which evi- 

 dently was cut off from that on vrhich La Fayette stands by a former 

 course of the river. This channel was later the loAver course of the Wild 

 Cat Creek and still contains a chain of ponds. The creek wa.s by some 

 means deflected and now joins the river several miles farther up stream 

 than formerly. 



The LaFayette terrace slopes gently from tlood-plain level back one 

 mile to the bluffs. It corresponds in elevation to the detached area in 

 the flood-plain and the low terrace above the bend. It is about four miles 

 long and is slightly higher at the upper end than at the lower. 



The West LaFayette terrace is two miles wide in its greatest width 

 and eight miles long. Opposite LaFayette it presents a bold blult" to the 

 river and lies at an elevation of one hundred and twenty to one hundred 

 and fifty feet above it. Two miles l)elow a Ioav terrace begins and ex- 

 tends between the higher terrace and the flood-plain nearly to the mouth 

 of Indian Creek. 



The most extensive area is the beautiful region embracing the Wea 

 Plains, southwest of LaFayette. This great terrace begins just below the 

 city and extends ten miles to the west line of the connty. Its width 

 averages at least foui- miles. Its height agrees with that of the West 

 LaFayette terrace, the narrow strip lietAveen lower Burnett's Creek and 

 the bluffs and Pretty Prairie. This correspondence in elevation seems to 

 indicate a former continuous surface of these teri*aces throughout the
