Search for a stone fortress built by the U.S. Cavalry to protect frontier settlers in the Wild West.

The archaeologists of TIME TEAM AMERICA ride to the rescue of a Wild West time capsule. In 1865, a unit of cavalry soldiers thought they had volunteered to fight in the Civil War. Instead, they found themselves sent west to defend pioneer settlers against angry Sioux Indians in what is now South Dakota. Upon their arrival, the soldiers built one of the few stone forts on the American frontier. The fort's quartzite walls still peek out from under a grassy field. Our team has just three days to map, dig, and uncover what remains of Fort James. What they find tells an intriguing tale of 1865 frontier life.
