Back in 1994, McIntyre was a naturalist ranger who did interpretive programs, carrying a wolf pelt into busy areas such as Old Faithful and Mammoth, drawing a crowd, and talking about wolves. Then the live wolves arrived. For almost two decades now he has worked for Doug Smith on the Yellowstone Wolf Project, though his job is still interpretation as much as monitoring. He’s an ambassador for the wolves, adding guidance and understanding to the way Yellowstone visitors see them. He knows the animals, individual by individual, pack by pack, their genealogies and their proclivities, as thoroughly as if he had written the script of this great canine soap opera himself. The female in her den at Soda Butte, he told me, is the fifth-generation descendant of the Canadian pair who acclimatized in the Rose Creek pen. With that statement, I realized: On that day with Mike Phillips 20 years ago, I probably looked her great-great-grand-mother in the eyes.
