Eh Cave Stuff- stick out to me.
“For the ancient Maya, caves and cenotes [sinkoles] were considered openings to the underworld,” says Holley Moyes, a University of California, Merced expert on the archaeology and religious use of Maya caves who was not a part of the project. “They represent some of the most sacred spaces for the Maya, ones that also influenced site planning and social organization. They are fundamental, hugely important, to the Maya experience.”
But until the concept of cave archaeology began to take shape in the 1980s, archaeologists were more interested in monumental architecture and intact artifacts than they were in analyzing the residues and materials found in and around objects. When Balankanché was excavated in 1959, caves were still mapped by hand in the dark and artifacts were routinely removed from their sites, cleaned, and later put back. Of all the incense burners found in Balankanché that were filled with material that could have provided definitive evidence related to the chronology of the site, for instance, only one was ever analyzed.”
