In the Gold Thread well, southwest of Sour Lake, the bine clays 
with calcareous nodules are overlain by 160 feet of sand and are 
apparently the clays No. 12 of the above section. 
It may also be noted that in the area occupied by these sands a 
number of salt licks and salt marshes occur. These extend across 
the country from the Trinity to the Calcasieu and cover areas from a 
few hundred yards to nearly 100 acres in extent. One of the largest 
of these marshes occurs in the immediate vicinnty of Sour Lake, and 
has an area of approximately 100 acres; another large one is located 
2 miles west of the Libbie well at Saratoga, and has an area of 
about 60 acres.
