Moose Loses Calf to Pack of Wolves in Denali National Park

In June, 2010, professional photographer Patrick J. Endres bought a one-day permit to shoot photos in Denali National Park. Endres had an uneventful day and was exiting the park around 8 p.m. when he and his friend, Hugh Rose, stumbled on a cow moose defending her calf from a lone wolf. Soon after, five more members of the pack arrived and went after the one-week-old calf from all angles, eventually taking it down.
