Mime mounds up to 2 m in height and 50 m in diameter are found all over the world. They are most common in North America. In some areas, they can be counted in the millions, they stretch for many kilometers across the landscape. But scientists have been puzzled by where they come from or who creates them.
Lead researcher Dr. Manny Gabe, from San Jose State University, explained that the mystery surrounding the Mime mounds is that until now, no one really knew how they formed. Over the past couple hundred years, people have thought that these are Native American mounds, or perhaps they appeared as a result of earthquakes or glaciers. Some have proposed a hypothesis about the alien origin of the Kurgan Mime. Now, a new study suggests that their architects are tiny shrews. Dr. Gabe is sure that the gophers have created mysterious mounds. The results are presented at the fall meeting of the American Geophysical Union in San Francisco.
And the essence of what is happening is as follows. Using a computer program, the researchers analyzed how the rodents move the soil when they burrow. The researchers found that in areas prone to waterlogging, ground squirrels gradually move to the “floor” above, adding a small amount of earth to stay dry. This was done by more than one generation of ground squirrels and continued for hundreds of years, until the Mime mound was formed. For hundreds of years, many generations of ground squirrels repeated this process until these tiny piles of soil grew into huge structures.
Dr. Gabe developed a computer program he called “digital gophers” and made them “work” the way real rodents do. To his surprise, mounds began to form in this virtual landscape. Virtual Mime mounds created by "digital gophers" are almost identical to the real ones. The mimic mounds in the computer model look similar not only in size, but also in how they are packed and how many pieces are obtained per unit area. This program replicated the real-life situation almost perfectly. But the question remains open, because ground squirrels are found only in America, while Mime mounds are found on all continents except Antarctica. However, Dr. Gabe explained that other underground mammals, such as moles, may be the architects of such mounds. Mime mounds in the United States were created by ground squirrels, says Dr. Gabe. It would be nice to dig into these mounds (in other countries) and see what kind of creatures live inside them. For Indian players, an
