is the most easterly extension of the Knobstone escarpment. Foothills 
are found in the northern part of township 1 north; they extend one mile 
to the east of the main escarpment, are low and for the most part unculti- 
vated. The Sub-carboniferous limestone which overlies the Knobstone 
has receded many miles to the westward, thus leaving the sandstones 
and shales to make up the hills of this region. In section 24, 2 north and 
S east, on the line between Clark and Scott counties, probably the highest 
part of the escarpment is found; it is 400 feet above the general] level of 
the country to the east. (The hills of section 24 and 25 are cut off from 
the main line by a gap cut by streams tributary to the Muscatatuck on 
the north and the Ohio on the south.) 
The line of hills now turns westward. then northwestward twelve miles, 
passing into Washington County, and again turns west. In township 2 
north, 6 east, there are several small valleys cut by streams tributary to the 
Museatatuck. The foothills are long, extending two or three miles north- 
east parallel to the principal creek beds. In township 3 north, the over- 
lying limestones extend to the eastern face of the Knob escarpment. 
In section 30, township 4 north, 8 east, the hills turn to the west, run- 
ning parallel to the Muscatatuck and White rivers. In places the hills 
“bluff up” against the river and in others the “bottom land” is a half mile 
or more in width. In the eastern part of township 4 north and 4 east, the 
line of hills makes a great bend towards the south; another deflection is 
made to the southeast in the middle of township 4 north and 8 east. In 
section 26, township 4 north and 2 east, in northwestern Washington 
County, limestone is found capping the escarpment 125 feet above the 
river bed and is found as the capping stratum for several miles farther 
down the river; the hills forming the border of the valley vary from 125 to 
300 feet in height. 
From Ft. Ritner, on the north side of White River, the hills extend 
northeast for six miles to near the town of Medora, then nearly north for 
ten miles to Freetown in the northwestern part of Jackson County. In 
the first seven miles of this portion there are no foothills, the White River 
bottoms extending to the face of the escarpment; farther north there are 
foothills and in many places there is a gradual rise from the eastern low- 
lands to the hills to the westward. In a few places only are the hills as 
high as they are to the south. One hill was measured which was 370 feet in 
height, but this was an exception. In the vicinity of Freetown, in town-
