Treasure in every form is cached throughout the area. There are numerous stories of some very hefty amounts that were stolen and never left the area, only to be hidden for 152 years a short distance from where it was taken. Follow the railroad would be the first clue to quickly finding something. I will tell you that the Salem Public Library, Harrison County Public Library and the Jackson County Public Library are great resources of individual accounts.
Lieutenant George Eastin of Morgan's men was captured by Union troops near Old Pekin. It is thought to be between the old road and railroad. Eastin told that he was in a wooded area trying to escape from the soldiers and that he buried his sword, gold and silver coins, his medals, uniform buttons and a knife before being captured. He never returned to find his cache after the war.
A few miles Northeast of Old Pekin, just South of Harristown, several of Morgan's men were cut off by pursuing Union troops. Pinned down in an orchard the raiders buried their loot and perished from the bullets of the Union troops. This cache could be found with some serious research and a little luck.
This does not even begin to describe what is hidden along John Hunt Morgan's raid through Indiana.
