The now-famous "Ring of Cenotes" (visible in NASA imagery) outlines one of the shock-waves from this impact event in the rock of ~66 million years of age, which lies more than 1 km below the modern ground surface near the centre, with the rock above the impact strata all being younger in age.
The now-famous "Ring of Cenotes," a geologic structure composed of sinkholes arranged in a semi-circle, outlines one of the shock-waves from this impact event in the ~66 million year old rock.
The presence of the crater has been determined first on the surface from the Ring of Cenotes, but also by geophysical methods, and direct drilling with recovery of the drill cores.
The existence of the crater has been supported by evidence including the aforementioned "Ring of Cenotes", as well as the presence of impact debris such as shocked quartz and tektites, a type of glass formed during meteorite impacts.
