The Bertrand sank in the Missouri River on April 1st 1865. It was headed to Montana to supply the gold rush towns along the way. It sank with a full load of merchandise on board. Over the years it was covered in the mud of the river. After the river was redirected by a channel in the 1960s, two men determined to locate it and in cooperation with the Federal government, discovered the riverboat and recovered 150 tons of items. Since 1968, over 250,000 items have been cleaned and cataloged with samples on display at The DeSoto Wildlife Refuge Visitor Center. What an amazing time capsule!
