Summary
| Description |
English: These are radiocarbon ages of organic material recovered down through a typical Mima Mound in the Mima Mound Natural Area Preserve, in Washington. These ages show that the mound began forming about 4600 years ago and grew gradually over time. These results, coupled with the computer model, essentially prove the theory that gophers built the mounds. |
