So what do you think ATS? Any Ideas on how these mounds were formed?
I've done a little more research on this and still can't come up with a good reason why or how these mounds were made.
Explanations ranged from seismic causes and even to pocket gophers.
According to a computer model, "mature" Mima mounds appear after about 500 to 700 years of scurrying and burrowing by pocket gophers. In the model, single gophers add a bit of soil, pebbles or dead plants to each mound over many generations — the animals are fiercely territorial.
"That's what makes it take so long; it's generation after generation living in these mounds and building them," said study author Manny Gabet, a geologist at San Jose State University in San Jose, Calif.
"What's really cool about this is scaled by body size, these are the largest structures built by any mammal not including humans," Gabet told LiveScience's OurAmazingPlanet. "In terms of effort, it would be like a single person building the pyramids."
