Tertiary.

Here it wili be seen that there is a stratum of sand and gravel 
beginning near 100 feet below the surface, and also that we have a 
mass more than 20 feet thick carrying considerable clay lying at 
a depth of nearly 200 feet. The well stops before the base of the 
Tertiary was reached, so that it is not known what lies beyond. 
Going back southward to Ford county, another well was put 
down on the high uplands about two and a half miles north of 
Dodge City. The bluffs for miles along the river near Dodge City 
have three distinct strata of sand and gravel strongly cemented 
with calcium carbonate into a more or less firm rock. They are 
separated from each other by beds of clay carrying a smaller 
amount of relatively fine sand. In places below these other beds of 
gravel likewise cemented are found.
