"On 8 June 1847, the Minnesota Packet Company was organized and soon began advertising the first regularly scheduled steamboat service on the Northern River (Mississippi River). Their first boat, the 41 ton Argo
soon became the regions' first confirmed terminal steamboat wreck. Sunk in October 1847, the Argo
, like almost every steamboat lost in the Northern River, was extensively salvaged with its machinery and cargo removed."
