 The freighter that ran aground in the Duluth Harbor is back in operation. Rising waters helped the cargo ship float free Sunday night after it ran aground hours earlier. The 990-foot American Spirit was fully loaded with tachanite on its way to Lake Superior. It nearly hit a wall while attempting to turn into the Duluth Superior Harbor. Officials say no one was hurt.
