Mima Mounds

Mima mounds are mysterious formations found in fields in various parts of the world, including China, Alaska, and in this part of southwestern Washington. This cluster has been designated a registered natural landmark to preserve and offer interpretations of the formations. The clearing is full of hundreds of closely spaced mounds, six to eight feet high, with a diameter around thirty feet. Various theories exist to explain the mounds, from glacial deposition to giant prehistoric gophers, though others believe they were formed by Native Americans.
