Banking on Treasure - Treasure Lead

Imagine a little town, situated along a river.

A torrential flooding like no other in recent history wipes through the town sweeping buildings and contents in its wake, including the bank.

Yes, the bank....and its contents, including two full safes.

Still lost to this day, likely on the bottom of the river, possibly buried in the banks, or possibly the surrounding field, if the river has moved position due to erosion.

Time to get out the backhoe!
