160 FULLER AND CLAPP — MARL-LOESS OF LOWER WABASH VALLEY 



it could be determined was always under 5 degrees, and it is believed 

 to be an original feature. In direction it appears to coincide, in a gen- 

 eral way, either with the trend of the White or with that of the Wabash 

 river. The observed range of the horizontal stratification is from the 

 level of the river flats to the 500-foot contour, a range of about 120 feet. 

 Above this level lines of indistinct banding, and of concretionary layers 

 concentric with the surface of the hills, were noted in several instances, 

 but no traces of a horizontal banding were observed. Figure 1 of plate 

 14 shows something of the character of the stratification. Several other 

 exposures exhibiting even more conspicuous lamination were seen, but 

 could not be photographed. The following list shows a number of local- 

 ities at which stratification could be readily observed at the time of the 

 field work in the autumn of 1902 : 



List of best Exposures of Stratified Marl-loess 



1. Kih'oy, I mile south of (northwest J section 9, township 4 south, range 13 

 west). 



2. Mumford hill's (southwest I section 31, township 3 south, range 13 west, and 

 section 36, township 3 south, range 14 west). 



3. Poseyville, 4 miles southwest of (northeast \ section 1, township 5 south, 

 range 13 west). 



4. New Harmony, IJ miles east of (northeast i section 6, township 5 south, 

 range 13 west). 



5. Patoka, 2^ miles north of (southwest i section 12, township 1 south, range 

 11 west). 



6. Hazelton, opposite railroad station. 



The best examples of interstratified gravels and sands are found along 

 the road south of Kilro}^ (section 9, township 4 south, range 13 west). 

 At an exposure on the west side of the road about a mile south of the 

 village there are about 10 feet of sand and gravel overlain by 8 feet of 

 marl-loess, the two being interstratified along the transitional zone. 

 About i of a mile from the town the following section is exposed :

Fossils. — Fossils were observed in about twenty-five localities in the area 

 surveyed. Their range is coextensive with that of the marl-loess, none 

 being found above the 500-foot level nor beyond the limits of the deposit 

 as described in the paragraph on " Distribution," page 156. They are
