Rare Wolverine Sighting in California's Yosemite National Park

California wildlife officials have confirmed the sighting of a rare wolverine in the Eastern Sierra Nevada Mountains, marking the second time such a mammal has been spotted in the California wild in nearly 100 years. Wolverines are members of the weasel family and are known to travel up to 15 miles a day seeking food. The declining American population of wolverines has made them candidates for protection under the federal Endangered Species Act. The state Department of Fish and Wildlife hopes to track the latest wolverine by collecting hair and scat and analyzing more photos and video from those rare Californians who have seen the mammals in the wild.
