The purpose of this report is to give results of investigations made in Polk and adjoining counties. Rice sand located on property owned by the Eden-Birch Lumber Company, approximately 1.5 miles west of Carmona, northern Polk County, and other deposits in Polk, Trinity, Tyler, and Walker Counties were examined. Volcanic ash, bentonitic clays, and artesian water were encountered while mapping the Eden-Birch locality, and a brief discussion of each of these is also included in the report.
