Desert Speaks 
Across The Great Desert
Season 9, Episode 2 of 10"Across the Great Desert" follows the 1909-1910 expedition of Norwegian scientist/explorer/writer Carl Lumholtz to the Grand Desierto (the Great Desert) in Sonora, Mexico. The adventurer explored the last undescribed, unexplored region of North America in the early part of the 20th century, spending months among the waterless sand dunes and salt mines of Northern Mexico from the Colorado River delta to the coast of the Sea of Cortez. The Lumholtz Expedition is an incredible story of survival for scientific purposes, featuring a re-creation of the journey. The program features ethno- botanist/anthropologist/historian David Yetman and a pre-eminent modern day explorer of this region, writer Bill Broyles.
