Sketchy Fact #26: Getting Biblical on the North American Plains

The largest gathering of animals ever observed was a swarm of Rocky Mountain Locusts that covered about 510,000 square km (197,000 square miles) of the American Plains in 1875. By contrast, Yellowstone National Park covers 8,983 square km (3,468 square miles). The locusts were extinct by 1902. No one particularly misses them.
