PLEISTOCENE OF CAPITOL HILL 169 



1. Till, weathered, brownish. About three feet. 



2. Till, buff, pebbly. About five feet, grading into No. 1. 



3. Till, gray, pebbly, grading into buff above. Four feet. 



4. Till, gray, alternating with sand streaks. Two feet. 



5. Loess, gray and buff, banded, abundant shells, lower sur- 



face sloping to east. One to two feet. 



6. Clay, buff, somewhat sandy in places, abundant pebbles. 



for most part rather small, some up to two inches, else- 

 where six to eight inches in diameter. Pebbles are 

 fresh limestones, quartzes, greenstones, and granites, 

 some of which are badly disintegrated. Shells of loess 

 types afso are abundant in this clay in places, while in 

 others they are rare or absent. Between this member 

 and No. 5 are rolled masses of gray loess with concentric 

 lamination well developed. Two to three feet. 



7. Clay, brown, jointed, loess shells abundant, no pebbles, 



probably a weathered loess. One and one-half feet. 



8. Loess, gray, shells abundant. One foot. 



9. Loess, buff, fossiliferous. Three feet. 



10. Loess, gray, fossiliferous. One foot. 



11. Sand, in lens extending 100 feet along Court avenue; here 



two feet thick, at its maximum, fifty feet west, six feet 

 thick. The sand is fine, yellow with brown streaks, and 

 presents masses of coarser, reddened material near the 

 top. It is strongly cross-bedded. The lens dips slightly 

 toward the northeast, in which direction it thins to about 

 two feet, but attains a length of over 150 feet. 



12. Loess, gray for about one foot, then grading down into 



buff. Shells are abundant and of the usual loess types. 

 At several localities along the line of this section there 

 are shown masses of dark blue loess which is rather 

 harder than the buff variety. Fossils are abundant here 

 also. These masses are enclosed by the buff loess and 

 some of them are as much as five feet in height and 

 ten to twelve feet long. This blue loess does not seem 

 to be distinct from the buff loess in anything except 

 color and doubtless is occupying its original position. 

 Exposed in gas main trench ten feet. Shales were not 

 reached at this locality. 



The lower body of loess, No. 12. is continuous with the loess 

 of the first section given, but it rises about ten feet higher in 

 the first section, as there apparently it was undisturbed by the 

 overriding glacier and by glacial waters. 



It is evident from its situation that the gray loess is an altera- 

 tion product from the buff loess. It is found uniformly above
