 Tough expedition through a dense, lush vertical jungle in Southern Peru that reaches an unexplored granite valley on a scale of Yosemite. Director Michael Brown and Chilean environmentalist Pablo Sandor climb one of the unnamed walls to reach a jewel of a lake they had seen from the air. Film helped Sandor s foundation win the prestigious United Nations Kofi Annon Award and grant for its conservation work in this pristine corner of the world.
