Imagine you see a cloud of dust. The ground begins to shake. You hear a deep rumble. Suddenly, thousands of animals surround you. They're bigger than horses. It's a buffalo stampede!
Long ago, buffalo swept across Minnesota’s prairies in big herds. Then pioneers and hunters came from the East and began shooting them. It's hard to believe, but they killed almost all of the buffalo.
Now here’s the good news - buffalo are back by the thousands.
Buffalo, also called bison, came to North America from Asia. They crossed the "Bering Bridge," a strip of land that connected Russia and Alaska during the last ice age, when the ocean was lower than it is now. The buffalo migrated south through the area that is now western Canada and spread throughout the prairies, where they found plenty of grass to eat.

The buffalo of the ice age were huge - much bigger than the buffalo we see today. Their horns spread as much as 9 feet from tip to tip. Asian hunters crossed the Bering Bridge into North America, just as buffalo did. They killed buffalo with heavy stone-tipped spears. The hunters later spread throughout North and South America. We know their descendants today as American Indians or Native Americans.
About 12,000 years ago, smaller buffalo appeared in North America. These smaller animals evolved from the larger buffalo. They looked very much like the buffalo we see today. These animals, too, were hunted by American Indians.
During the ice age, herds of buffalo streamed across the Bering Bridge from Russia into North America. Early buffalo were much larger than the buffalo we see today.

Many tribes of Plains Indians, such as the Dakota and Cheyenne, hunted buffalo. It was tough to kill buffalo with only spears and arrows. Sometimes hunters scared the buffalo to make them stampede over a cliff. Other hunters drove herds into canyons and then shot them as they jammed together. Some Indians dressed up as wolves to sneak up on grazing buffalo. After spaniards brought horses to North America in the 1500s, Indians hunted buffalo on horseback.
After the hunt, entire bands would prepare the meat and hides before they spoiled. The people ate the meat. They dried some of it and mixed it with fat and berries to make small cakes called pemmican. They used buffalo hides for warm robes and the coverings of their tepees. They made tools from the bones and decorated the skulls as ceremonial objects.
Plains Indians were still hunting buffalo 150 years ago, when white pioneers moved west. Pioneers didn’t want the herds trampling their land and fences. They killed every buffalo they could find. Some white hunters killed buffalo for sport. Often they took only the hides and left the meat to rot. Buffalo bones littered the prairie.
