Underground view

When Christopher Pacitto drills deep for soil samples, he knows exactly what he's looking at because he's been down there himself.

The Fort Myers engineer is an advanced cave diver, exploring Florida's underground caverns where few people have ventured. Pacitto says cave diving lets him see the various geological features below ground that he analyzes when his geotechnical equipment bores into the earth.

“I get to see it from the inside,” he says with a smile.
