One of two Stele on the site.
"During land clearing in 1964, the most enigmatic archaeological features of the site were discovered near the main burial complex. These were identified by Bullen as ceremonial stones or stelae.
Stele #2, which is located near the center of the plaza behind the visitor center, like stele #1, has never had an excavation to a depth of more than two feet. Additional archaeological investigation may reveal the stones’ true uses. While many theories have been developed on how these marker stones were used by the people that erected them, each theory has many unanswered questions.
Were these stones used. to anticipate seasons using the celestial bodies? Do they have some as yet undetermined relationship with the burial mounds. Was there intended placement with regards to burial mounds? This is not known, however due north of stele #2 there is another burial mound."
