Big trout saved from close call with extinction

Fisherman Brian Dunn weighs a Pilot Peak strain of Lahontan cutthroat trout at Pyramid Lake in Nevada on April 18, 2013. The fish weighed six pounds. A species once thought extinct, the strain of trout has been re-discovered and returned to its original home north of Reno. It is the largest freshwater trout in the world.
