Watch: Officials survey Silver Bell Mountains, see bighorn sheep and mountain lion
Arizona Game and Fish Department Tucson did a survey of the Silver Bell Mountains, west of Marana, recently and saw more than 160 bighorn sheep and one mountain lion. "The herd there is the largest among four ranges in the Tucson area, which now has more than 400 bighorns in part because of translocations," the department said, adding that the state's bighorn population has grown from 1,500 in 1957 to 6,000 today.
