Bedrock topography of northeast Iowa

The bedrock in Iowa (Hershey, 1969) is generally overlain by deposits of glacial drift and alluvium, which range in thickness from less than 1 foot (0.3 m) to more than 400 ft (18 m), respectively. The configuration of the bedrock surface is the result of a complex system of ancient drainage courses when were developed during a long period of...

Quality of water in the Red River alluvial aquifer, Shreveport, to the mouth of the Black River, Louisiana

Chemical analyses of water samples from 296 wells in the Red River alluvial aquifer indicate that the ground water in the valley is generally hard (more than 120 milligrams per liter) and has a high iron concentration (greater than 6,000 micrograms per liter). The predominant ions found in the water were calcium and bicarbonate. However, in places...

Bedrock topography of south-central Iowa

The bedrock surface in Iowa is covered nearly everywhere by unconsolidated deposits of glacial drift and alluvium which range in thickness from less than 1 foot to more than 400 feet, and from less than 1 foot to about 60 feet, respectively. The bedrock surface is the result of a complex system of ancient drainage courses, which were developed...
