VLA comment (DEE): Bison. Elk. Galloping away, literally, having to stop to catch their breath, then galloping again….Think Supervolcano. Think caldera under Lake Yellowstone. When the birds leave, it’s time to buckle up… they will be the last to go.
VLA comment (Stella): Signs signs everywhere signs. Here is video of bison evacuating Yellowstone Park, an area with great potential for massive seismic activity. Other animals are leaving as well; 1/4 of the Elk herd has already left.
