This undated photo provided by the California Department of Fish and Wildlife shows a Paiute cutthroat trout. For the first time in nearly a century, the California trout species will swim in a mountain creek that is its native habitat, marking a major milestone that conservationists hope will lead to a thriving population and removal of its threatened status. About 30 Paiute cutthroat trout will be plucked Wednesday, Sept. 18, 2019 from Coyote Valley Creek and hauled in cans strapped to pack mules about two miles (3.2 kilometers) to be dumped back into a stretch Silver King Creek in Alpine County's Long Valley, where the shimmering species glided through the cold water for thousands of years.
