Amateur Photographer Captures a Grizzly Bear Chasing a Bison Down a Highway in Yellowstone

A series of 16 photos from Field and Stream of a bear chasing an injured bison right past an amateur photographer:

Alex Wypyszinski, a retired professor and amateur photographer, shot this amazing series of photos of a grizzly bear chasing down an injured bison when he stopped to take photos of geysers in Yellowstone National Park in May. We got the story from the man behind the camera, who works at a post office in the park during the summers.
