Grand Teton National Park officials are seeking the public’s assistance in identifying two men who approached a baby bison last week.

Two individuals were seen approaching and touching a bison calf at the southern end of Elk Ranch Flats in the park at 1 p.m. on June 4, according to a statement from the National Park Service. The incident is currently under investigation, and anyone who recognizes the men or has information is asked to contact the park.

In the wake of the final report about the floating foot discovered at Yellowstone last summer, local leaders remain optimistic about tourism this year given that there were no signs of foul play and fatalities have previously occurred at the national park.

Yellowstone National Park, which sustained damage from heavy flooding, mudslides and rockslides last month, will reopen its north loop Saturday to all visitors, just in time for the Fourth of July holiday weekend.
