Archaeology digging is never always gold pots and treasures

Archaeology is not always a fruitful event in which you expect to dig up valuable artifacts in which one can deem as treasures in materialistic values. People spent efforts in understanding history of mankind. Sometimes, a dig can continue without hitting into anything with value. Archaeologists, however, continue with their best efforts in finding answers of the past, even how minimal one can get out from the different layers of earth. This video clip from youtube is a good example of it all.

You don't expect all digs to be successful. Sometimes, months can go by and still remain futile. But, Archaeologists do it piece by piece so that we can always have a bigger picture of our history.
