A comparison of this section with the Underwood section shows a con- 
siderable difference. In the latter there is but little level country; the 
Guinea knobs are on the east; the outliers of the western knobs are four 
and a half miles to the west, and it is several miles farther before the lime- 
stone is reached. In the Scottsburgh section there are no outliers, and 
limestone is found on the second hill. The knobs make a great bend to the 
west in running through township 2 north and township 3 north, hence the 
difference in the two sections. 
The Weed Patch Hill section was run along the north line of township 
8 north. It is 30 miles long. It begins at the White River, two miles 
south of Columbus, runs across Brown County over Weed Patch Hill and 
ends in Monroe County. 
For two miles and one-half the country is level and is covered to a 
depth of 30 feet or more with alluvium. The next four miles is rolling, the 
first two miles of which is covered with glacial clay, the latter with resi- 
dual clay. A well section in the first hill shows the Goniatite limestone to 
be 40 feet above the surface; this is its eastern limit. 
The higher hills begin six and one-half miles west of White River. 
The first hill rises almost abruptly 150 feet and is almost entirely made up 
of muddy sandstone. Throughout the rest of the section the hills are steep 
and high. In many places it is but 300 or 400 yards from one hill to the 
next, and the hollow between is 150 feet deep and sometimes deeper. 
Shale is found in the deepest hollows for the first six miles. Farther on no 
shale is found except in thin layers at various heights in the sandstone. 
This is one peculiarity of the rock in this section. : The sandstone greatly 
predominates; in fact, it is 22% miles wide, and through it there are these 
thin beds of muddy shale. All gradations between the nearly pure sand- 
stone and shale are found and in several places the sandstone is nearly 
blue. 
Weed Patch Hill was made 1,135 feet high by the barometer; the 
correct height is 1,147 feet. Sandstone is found all the way to the top. 
It is much higher than any of the hills on either side. 
Seven miles farther west Salt Creek valley is crossed; it is one-half 
mile wide. Still farther west, a mile and a half east of the west end of the 
section, there is a layer of fossiliferous limestone. It is found at the 
base of the hill in the sandstone, and is 15 feet thick and is made up al- 
most entirely of crinoid stems. One-fourth of a mile farther west, at the 
base of the next hill, there is a fifteen-foot layer of blue shale.
