HLAWORTH. | The McPherson Equus Beds. Dont 
dence of this theory he cites some boulders on Battle Hill as being 
of glacial origin, dropped or deposited by a stranded iceberg from 
the terminus of the ice sheet. 
The boulders on Battle Hill, Battle Hill township, McPherson 
county, are not the rounded quartzite boulders of the moraine, but 
eross-bedded sandstone of the Dakota formation lying nearly in 
place. They are about 3 feet thick, hard and angular, some of them 
quite jarge. There is also an absence of other moraine material, 
which a melting iceberg or ice sheet would certainly have deposited. 
Itocks very similar to these may be seen in place a mile southeast 
of Salina, two miles north of Twin Hills, (northeast corner of Del- 
more township, McPherson county,) and four miles west of Battle 
Hill. Here the soft, almost incoherent sandstones, removed from 
beneath the hard sandstone, which allowed the large blocks of the 
latter to gradually tip and tilt over the surface of the hill, and some 
of them have worked their way down its sides some distance. In 
one of these, on the northeast face of the north hill, the lower part 
grades into brownish Dakota sandstone. 
The elevation of Battle Hill is 1550 feet, which is about the same 
as the elevation of the highest of the deposits of the Equus beds. 
The elevation of the terminus of the ice sheet in Shawnee and 
Wabaunsee counties, so far as definitely located, is about 1050 feet, 
or not over 1100 feet above sea level! The planation of the surface 
is so slight that were it not for the small amount of material left 
by the glacier it would have been difficult indeed to recognize the 
former existence of glaciers in that portion of the state. Conse- 
quently it seems probable that the ice sheet was comparatively thin 
at its southwestern portion, the limit of which is even yet not en- 
tirely known. The elevation of the divides between the Kansas and 
Marais des Cygnes rivers south of Topeka is 1100 feet. This is over 
400 feet below the boulders at Battle Hill, or the more elevated de- 
posits of the Equus beds. How far up the Kansas river the loess 
is found is not known, but it probably does not extend above Topeka 
as far as to the summit of the flint hills in Wabaunsee county. It 
seems probable, therefore, that the waters of the Kansas river 
would have flowed around the foot of the glacier to the east of
