North America's largest rodent is known for its stick and log construction. They are semi-aquatic, building their lodges and dam on rivers and streams. They are herbivores with webbed hind feet and chisel-like teeth for chewing wood. In Glacier, Lower McDonald Creek is a great place to see beavers.

Some of the first Anglo traders came to the area to the hunt and trap the beaver for its prized pelt. Read about how beavers impact their environment.
