A collection of Civil War era artifacts has returned to its home at the DeSoto National Wildlife Refuge along the Missouri River.

More than 250,000 artifacts from the Steamboat Bertrand Museum Collection were removed just before the 2011 flood and stored at a warehouse in Bellevue, Nebraska. The collection is an archaeological time capsule of 1865 America.

Museum officials say the collection was inventoried and inspected while the refuge and the collection's home, the DeSoto visitor center, underwent major repairs over the last two years.
