The Devil’s Sinkhole near San Antonio is a 400-foot deep, huge hole in the ground.

It’s home to millions of Mexican free-tailed bats in the spring, and it spreads out into a series of caves like Swiss cheese.

Visitors can’t go into the cave but thanks to a group of scientists and their high tech computers, scanners and lasers, they will soon be able to take a virtual tour of the cave.

A group of elite cavers, biologists and geologists are mapping the inside of the sinkhole using laser technology called LiDAR, which stands for Light Detection and Ranging.
