The first entry in the Guidebook Series details a field excursion to the Eastern Llano Region of Central Texas in 1958. Retrace the footsteps of Virgil Barnes and the other state geologists in attendance: 

Stop 1. Honeycut Bend

Fourteen black-and-white geologic maps prepared in 1957 and 1959 and obtained from the Department of Geological Sciences, University of Texas, and sold by the Bureau of Economic Geology. Geology compiled by F. L. Whitney; drafted by S. Espey, W. M. Strong, or W. L. Brooks; edited by K. P.

Steeply dipping shales and interbedded sandstones presumably of the Ouachita facies have been discovered along the Colorado River in Burnet and Travis counties, Texas. Previously the Ouachita facies was known in Texas only from bore-hole samples.

The information contained in this circular was gathered by a unit of the WPA Mineral Resource Survey of Texas, a project sponsored by The University of Texas at Austin, Bureau of Economic Geology.

Travis County is located on the Colorado River at the west or inner margin of the Gulf Coastal Plain. Its principal mineral resources are clay, limestone, sand and gravel, surface and underground water, and possibly petroleum.
