Overview
- Photographer Julie Argyle recorded the late-May encounter at Grizzly Hill and later posted the footage to Facebook, prompting fresh coverage this week.
- Argyle wrote that the pair had been cautioned about 10 minutes earlier not to climb the hill because the bison were roughhousing.
- The video shows the animal rushing past the couple, with no serious injuries reported in the accounts cited by outlets.
- The National Park Service estimates roughly 5,400 bison in Yellowstone and notes they can run up to about 30 mph and are considered aggressive and agile.
- Yellowstone advises keeping at least 25 yards from bison, citing a history of one to two bison-related injuries per year and only two deaths since 1972.
