In the late 1980s, a shocking discovery was made. What was found was north of Kansas City, about 45-to 50 feet below a corn field. A mule. A mule in its harness and still tied to a rail. Due to the depth of the find, and the lack of oxygen, the deceased mule was quite well-preserved. 
Along with this mule was found about 200 tons of various supplies. Food items of all types, clothing, simple farm equipment, and even fine and intact China.
Was this poor mule responsible for transporting 200 tons of cargo? Nope – that would be ridiculous. 
The Mule was a passenger n the Steam Boat Arabia when she sunk in the Missouri River in 1856. The steamboat, the mule, and the supplies were lost for over 130 years. But how did they all end up 1/2 mile from the river and 45 feet under a corn field?
