236 EECORD OF DEEP- WELL DRILLING FOR 1905. 
728. Well at Groningen, Pine County. 
[Well begun July 1, 1904; completed August 10, 1904. Authority, A.J. Carey, of the St. Paul Artesian 
Well Company, contractor. Samples preserved.] 
The sandstones which underlie the soil and clay, the latter deposited during the Ice Age, 
form part of a ve^y old formation dating back to early Paleozoic time. The sandstone is 
locally known as the " Kettle River sandstone " and is believed to be a part of what has 
been called the "Basal Sandstone series," of middle Cambrian age.

of water was struck at 17") feet, but the principal supply is from 300 to 320 feet. Water, 
rises within 22 feet of surface and was not lowered by pumping 260 gallons per minute.

The formations penetrated by this well are clays, sands, and gravels varying in age fron 
Quaternary to late Tertiary (Pliocene). The water-bearing beds have been developed by ;.,j 
great number of wells along the Gulf coast of Mississippi.

This well, like most of those along the Gulf coast of Mississippi, develops a water-bear I 
gravel that occurs in the Grand Gulf formation, which is of Pliocene age. The formati 
overlying the Grand Gulf are of Quaternary age and include the Biloxi sand and Pontcl 
train clay.
