Remnant of Sergeant Floyd’s Casket at Sioux City Public Museum

Visitors to Sioux City should not miss this state-of-the-art facility featuring hand-on exhibits and interactive displays of local and regional history.

When Charles Floyd died on August 20, 1804, the men of the Corps buried him on a bluff overlooking the Missouri River, south of today’s Sioux City, Iowa.  There’s no mention in the journals of how he was interred – obviously, there wasn’t time to create a wooden coffin for his body.  It’s likely he was wrapped in a blanket.

But if you visit the Sioux City Public Museum, you’ll see this chunk of wood that is said to be a remnant of Sergeant Floyd’s casket.

Year after year, the Missouri River slowly eroded Floyd’s Bluff, and rain exposed the end of the grave and washed away the cedar post that the Corps created to mark the site.  So in 1857, concerned citizens of the little town of Sioux City recovered what remains they could find and placed them in a walnut coffin. They buried it 600 feet back from the river and remarked the grave.

After Floyd’s journal was discovered and published in 1894, there was renewed interest in his story and the 1857 grave marker was stolen by thieves.  So his remains were moved once more on August 20, 1895, and placed beneath a large stone slab.  That’s when this piece of the 1857 walnut coffin was recovered and retained by the Floyd Memorial Association.
