A common goldeneye duck paddles past a snowy bank—and toward the reflection of a gnarled tree stump—in Lake McDonald, part of Waterton-Glacier International Peace Park.

For 75 years the combined 1.14 million acres (0.6 million hectares) of Canada's Waterton Lakes National Park and the U.S.'s Glacier National Park have been designated, and jointly managed, as a transboundary conservation area—the world's first international peace park.
