The Mysterious Mima Mounds

The first thing thats odd about the mounds is the similarity, regardless of location. With few differences, the mounds in Kenya are like the mounds in Mexico which are like the mounds in Canada which are like the … well, you get the point. All the mounds are heaps of soil from three to six feet tall, often laid out in what appear to be evenly spaced rows. Not quite geometric but almost. What’s especially disturbing is that geologists, anthropologists, professors, and doctors of all kinds - plus a few well-intentioned self-appointed “experts” - can’t figure out what they are, where they came from, or what caused them.

The name Mima mounds originates from the Mima Prairie in Washington state, where hundreds of the grassy bumps are located. Mima mounds aren't only located in Washington state, they also exist in Arkansas, California, Louisiana, Texas, Idaho, and Wyoming, and in other countries including Mexico, Canada, Argentina, China, and Kenya.

Excavations made into the Washington mounds show that underneath a blanket of prairie grass lies a mixture of loose sand, fine gravel, and decayed plants.

Bernard Hallet, a geologist at the University of Washington explains that this is unusual, as most land surfaces have a top layer of organic material, dead plants and animals, no more than half a meter (1.6 ft) thick, while Mima mounds are made of organic-rich soil more than 2 meters thick.

Here is a new article on the Mima mounds. They still don't know what causes them but they are going to measure them with lasers.

Laser mapping may help solve the mystery of the Mima Mounds

Airborne laser surveys may help narrow the many theories that attempt to explain the origins of grassy mounds that dot Southwest Washington.
