The Digging Site is an area in the desert of Tanos. It was discovered by Miles. Miles was bored of his Magic Box and had a rough day, back in 2010, so he kicked the box hard.
The bottom came loose and a treasure map was hidden inside the hidden compartment that was revealed. Miles packed his stuff and went off to find the treasure. Therefore in 2010 Miles Magic Box wasn't active, since Miles was gone.
On August 23rd 2010, Miles finally found out how to dig into the hard soil.
What Miles found out, is that there are ants deep underground. If you bring him 2 food items, he will crumble it, the ants will loosen the soil and a dinosaur bone can be found.
