Yuma Gold

After serving an eight year sentence, for a crime he didn't commit, Ben Ruby is paroled from Yuma Territorial Prison.  Along with detailed knowledge of a 300 year-old Spanish Galleon buried in the dunes of Imperial Valley, Ben uses a treasure map, in the form of trinkets, to set out to find the ship.  If following up on an old tale wasn't difficult enough, Ben has to outrun the man that put him in prison, as well as a breach in a Colorado River dam that threatens to flood the entire valley.
