Inscription. The ridges located here are the remnants of a six-mile diameter circular feature created some 85 million years ago by an estimated 1,000-foot diameter asteroid. The area at the time of impact was a shallow sea. The ridges consist of a variety of metamorphic rocks and surround a central area comprised of large jumbled blocks of younger geologic strata. Drilling in the central area of the crater recovered fragments of rocks showing characteristic mineral alteration only associated with impact structures. The structure, although known for more than a century, was first identified as an impact crater in the 1970s.
