There were no wolves that July afternoon on a trail tracing the Green River in the west of Wyoming.
But in pursuit of those cousins of canines came hiking three people: two men from the state Game and Fish Department, and a woman from the US Fish & Wildlife Service.
They were looking for a pack that summers here, feasting on elk early in the season, then hunting cattle down below.
Each year when the wolves, only three or four in the pack, begin devouring the pricey cattle, they become the hunted, too.
"This is great country to be a wolf," the woman said. "Until August. Then the guns come out."
