Join Preston Sowell, a photographer for the Sibinacocha Watershed Project as he journeys up into the Peruvian Andes studying a high-alpine lake, Laguna Sibinacocha. Under the surface of this lake are ancient ruins, believed to have been made by the Inca or pre-Inca people more than 600 years ago. Come along with Preston and his team as they continue to study this environment and the animals that live there.
