Once again our government has thought up a way to spend a lot of money to solve a very simple problem. Today you can run a fiber optic scope down the hole and see what is in there. Back in the Vietnam era we just blew it up! Still the simple solution for Master Blaster. How many educational degrees does it take to figure that one out? That hole was blasted there in the first place. I'm not aware of the exact location of the drill hole (nice picture - hope it will be preserved - hole I mean). CCC work was very important to get us out of the depression and I still admire their work across America.
