A large, roughly circular sinkhole of considerable depth, it served for centuries as a site of ritual activity.

Objects of extraordinary variety and value — jade, gold, worked bone, ceramics, rubber, wood, copal incense, and more — were deposited into it.

Human remains have been recovered from the cenote as well, though the demographic picture of those remains is different from what the chultún analysis has revealed.

The cenote and the chultún, while physically near each other, preserve distinct patterns of activity.

The chultún that is the subject of the 2024 study is described as having been repurposed — that is, it was not originally constructed as a burial facility.
