We're going way back for today's Geo Quiz, about 3,000 years back.

Back around the 7th century BC, the first Olympic games were up and running in Greece. And the Polynesians were sailing all the way to the Hawaiian Islands.

Meanwhile in a remote corner of Central Asia it seems that some ancient shamans were experimenting with drugs. Researchers exploring a tomb there have turned up...an ancient stash of cannabis.

Neurologist Ethan Russo led a team of scientists to investigate the site:

"The site in question is an area extremely remote about it's about the furthest inland place one can get to on Earth, about 2500 km from either the Arctic Ocean or the Indian Ocean, and its near the second lowest spot on Earth after the Dead Sea."

This archaeological site is at the edge of one of the world's great deserts, the largest one in Asia.

Can you name the desert?
