Yellowstone National Park, 1990

A mountain lion peers out from a rocky nook in Yellowstone National Park. Demonized by farmers and ranchers, mountain lions were almost hunted out of existence until substantial research in the 1960s helped dispel fears about these mysterious big cats which are in fact more likely to run up a tree than attack a human.
