“I do not live in water. I cannot even swim! Mx. Beaver—Humboldt—I am lost. I cannot find my way through this foul swamp.” “Foul!” squeaked Humboldt. “Swamp! It is no swamp.

Its water source is primarily rainwater, which results in a highly acidic and mineral-poor environment.” Eleven thousand years, and the beavers had grown didactic.
