Yellowstone national park officials have reiterated warnings to stay at least 25 yards away from large wild animals – as well as 100 yards from bears and wolves – after a bison gored a 47-year-old woman from Arizona on Sunday.

The goring left the woman with “significant injuries to her chest and abdomen,” officials said in a statement.
