Information about the Columbia Mammoth:

The Columbia Mammoth is an extinct mammal that was native to much of North America down into Central America. This large elephant was part of North America's "Megafauna" (which are very large land animals) much of which went extinct some 9,000 years ago. There is some discussion as to why these large land animals, along with others, went extinct, but it is believed a series of events such as climate change, the arrival of humans into their range along with perhaps a small meteor striking the earth might have been the cause of their demise. The Columbia Mammoth was the largest of the mammoths and the largest elephants ever to have lived, measuring 13 feet (4 meters) tall and weighing up to 11 short tons (10 metric tons.) It was 10.7 feet (3.3 meters) long at the shoulder, and had a giant head that accounted for 12 to 25 percent of its body weight. The tusks were impressive too, and could grow to be longer than 6 feet (two meters) It was a herbivore, and likely fed on a variety of different types of plants and perhaps even fruits. The Columbia Mammoth is the state fossil of both Washington and Nebraska state.
