They are called the Gray Ghosts, slipping through the northern forests with a presence that feels more imagined than real. These endangered Central Mountain Caribou (a ecotype of the Rangifer tarandus caribou), once counted in the tens of thousands, now number only in the hundreds. Habitat loss and shifting ecosystems have left them at the edge of disappearance. To see them at all is a privilege, a glimpse of a vanishing world.
