SWEM: RKl'OkJ' ON 'IHF. GLACIATED AREA OF KANSAS. 157 



Fifty feet would he a fair estimate of the average depth. In going 

 south from central Jackson county the drift becomes less in depth 

 very noticeably. 



I have said that the usual color of the drift is dull yellow. Below 

 are some variations from this. More might be given, but these are 

 typical: 



Two miles from Denton on road to Everest is the following sec- 

 tion, made by a creek. 



1. Soil, I ^2 feet. 



2. Lead colored clay, hard and tough, at base is layer of 

 pebbles, 4 feet. 



3. Red sand with pebbles, 4 feet. 



4. N'ery fine white sand, 3 feet. 



5. Brilliant red sand to bottom of section, i foot. 



Four miles west of Larkin is the following. The laminae here 

 are unusually distinct. 



1. Soil and \'ellow cla_v, 3 feet. 



2. Brown sand, compact, with gravel, '2 inch. 



3. Brown sand, 2 V2 inches. 



4. Deep brown coarse sand, i V, inch. 



5. Coarse red sand, 9 inches. 



6. White clay, 5 inches. 



7. White sand, 5 inches. 



8. Fine red sand, 4 inches, 



9. Black sand, compact, 2 inches. 

 10. Dark brow^n sand, 10 inches. 



Below this are alternate layers of pebbles and sand. These lie 

 upon weathered shale, which rises about 5 feet above creek bed. 



A generalized section of the whole drift region would be as 

 follows: 



1. Soil. 



2. Yellow clay, occasionally with pebbles, and sometimes over 

 sand. 



3. Lead colored clay passing graduallj' into 



4. Lead colored shale. 



5. Limestone. 



I found the following localities of special interest: 



I. Holton. 



Elk Creek flows at the base of a hill perhaps 60 feet in height, 

 and makes a very striking section. This section is almost directly 

 north of Campbell University. It is 60 feet in length, and varies 

 in height from two and three feet to twelve feet. At the left end 

 can be seen five feet of brittle lead colored clay in which there are a
