Dead of winter in Yellowstone’s Lamar Valley. Wolves and Bison coexist, but if the Bison weaken they may fall prey to the patient wolf pack. Absent obvious illness or weakness in the Bison, the wolves remain a safe distance knowing that the injury they would incur in a frontal attack would undoubtedly lead to their own demise. Yellowstone National Park, Wyoming, USA.
