358. Well at Oft'erraan, Pierce County. 
[jWell begun April 1, 1905; completedJune 9, 1905. Authority, Hughes Specialty Well Drilling Com- 
pany, contractor. Incomplete set of samples preserved.] 
All the formations below the thin surface soil at this well are probably of Tertiary age. 
They include beds laid down in Pliocene, Miocene, and Oligocene or Eocene time which 
have not been well enough identified to permit formation names to be given. The lime- 
stones below 500 feet are thought to belong to the Jackson-Vicksburg group. 
Record of well of Southern Pine Company, on lot No. 269, Fourth district, Pierce County.

The red pebbly sand and stiff red clay near surface probably belong to the Lafayette 
formation. The marl and limestone below are of Tertiary age, but no attempt is made to 
^correlate them with formations which outcrop farther inland. The water-bearing lime- 
stone at the bottom is part of the Jackson-Vicksburg group of early Oligocene or late 
Eocene age.
