Heat and Dust (E02)

From the Andes peaks, we follow the path of the relentless wind, sweeping east through Patagonia's dry desert. We discover a weird world of maras – giant guinea pigs – and desert-dwelling penguins, and witness the first faltering steps of baby guanacos – Patagonia's very own camels. People live here too – brave souls who have taken on this arid world and carved out a home. (BBC)
