The mineral resource survey of Texas, which is being made by the Works Progress Administration, has been in progress since January 1936. Up to September 21, 1936, the survey has been carried out in 27 counties located in 12 of the 20 Works Progress Administration Districts of the State of Texas. The location of these counties is indicated on the accompanying map (Ed. note: No longer available, April 1971).

In the north and northeast parts of Clay County, an area of approximately 70 square miles is covered by fluviatile deposits, including the present stream valleys and the ancient terraces, or flood plain remnants, of Big Wichita and Red rivers.

The largest stream in Bell County is Little River, which is formed by the confluence of Leon and Lampasas rivers southeast of Belton and nearly south of Temple. For the study of river terraces in Bell County, the area south of Temple on Little River was chosen because an excellent development of terraces may be seen there, and it was believed that conditions in that area may be typical for other streams in the county. A plane table map was made for the vicinity of the villages of Little River and Sparks, and the traverse was continued south to the town of Holland.

A mineral resource survey of Texas has been started by the Works Progress Administration, with the Bureau of Economic Geology of The University of Texas acting as sponsor. The purpose of the survey is to assemble information and make it available to the public. Through a separate project, sponsored by the State Planning Board, the results of the survey, as they are received in Austin, are being assembled for publication.
