Why Did It Take 20 Wells to Dig a Steamboat Out of a Cornfield?

In 1856 a snag sank the steamboat Arabia on the Missouri River near Parkville. In 1987 she was found under a Kansas cornfield, half a mile from the river, as deep as 45 feet. How does a river bury a 171-foot boat and walk away from it? And why did digging her out take twenty wells pumping 20,000 gallons a minute? We read the river men, an Army engineer's history and the newspapers of 1856.
