Silk Road
Out of Eden Walk: Trekking through Uzbekistan
The Silk Road in Uzbekistan was a caravan route, a path for explorers and traversed by Soviet-era train tracks. National Geographic Explorer Paul Salopek tells host Carolyn Beeler about this Central Asian country that has been a thoroughfare for explorers, traders and conquerors across the centuries. He crossed it on foot as part of his 24,000-mile Out of Eden Walk.
