WILLIAMSON COUNTY, Texas (KXAN) — An undiscovered cave feature has been exposed on Cambria Drive that had not been filled in with concrete along with the rest of the Cambria Cavern.
The Williamson County contractor, Chasco Constructors, was working to reinstall a gas line under Cambria Drive Friday morning.
During the installation process for the line, an area of the cave not filled with concrete was unearthed. Work was immediately halted, and Cambrian Environmental was contacted to look into the feature.
The Texas Commission on Environmental Quality was brought in, and the county estimates it will take a few days to investigate along the gas line.
The size of the feature is still undetermined, and it is unknown if it connects to other areas of the cave.
Cambria Cavern was originally measured about 200 feet long and 20 feet deep. As researchers dug core samples, they also discovered another chamber.
The hole in the ground and what was underneath fascinated those living in the Brushy Creek neighborhood, who gathered around when it first opened to try to sneak a peek inside, and as subsequent work was being done. Someone even illegally entered the cave at the beginning of April, prompting heightened security.
The new opening is not currently large enough for a person to climb into for investigation. Consultants will have to use hand tools and a small excavator to inspect the size of the area.
The immediate area has been plugged to avoid having sediment fall into the feature or the nearby aquifer.
