This is the gold on which I based Rightfully Ours when I first drafted it in 2010. At the time, treasure hunters were searching farther east, closer to the Williamsport locale I chose. After many revisions, the story developed into a premarital chastity-themed book, but this treasure still plays an important part in both the plot and the themes.
This NBC video shows a nice map of the route the gold would have been taken. You can see it skirts Williamsport.
