Longhorn Caverns State Park. One of the Civilian Conservation Corps (CCC) project from the 1930s. We’ve got them all over Texas; all still in use; all fantastic in their use of local materials. Looking down to the cave entrance. 
Looking back up from partway down. 
If you’re not familiar with the CCC, it was a New Deal program that operated after the Great Depression from 1933 to 1942 all over the United States, providing work for unemployed unmarried men. As well as providing employment and training, it was dedicated to the conservation and development of natural resources. The CCC literally built the Texas State Park system.
