Are these animals running for their lives?
The mass exodus from Yellowstone National Park has Wyoming residents fearing the creatures know something they don’t.
KPLR reported bison and other animals heading from the hills could prove theories about minor earthquakes that could soon set off the Yellowstone Super Volcano.
Authorities have recorded many smaller tremors hitting the area over the last few weeks and said the more shakes, the better the chance a volcano could be brought out of its dormant state.
