The cave stretches eastward from the site of a sinkhole, located in a neighborhood in the Brushy Creek area. The height at some points of the cave reaches 22 feet, with an average height of 10 to 15 feet, according to a county news release.

The county said structural engineers will explore the site to help determine the cave’s stability.

They'll also decide how to repair the sinkhole, which could take several weeks as the assessments and repairs take place.
