Modern Marvels

Season 10 Episode 39: Sandhogs

Sandhogs work hundreds of feet down, where it is dark, damp, and dangerous, challenging nature’s awesome forces to drive tunnels through solid rock and sinking mud. They drill and blast, bore, mine, and muck. The painstaking process continues for days and yards, months and miles. Tragically, many sandhogs have been killed or injured in the process, but ultimately theirs is a story of triumph and survival. Join us as we review their impressive achievements and history.
