Sistema Cheve

[2] As of 2021[update], the present limit of exploration in Cheve, at 11.77 kilometres (7.31 mi) from the nearest entrance,[1] represents one of the most remote locations ever attained inside any cave on Earth.

Due to the logistical difficulties of continuing exploration from this point, expeditions are focusing on finding mid-way entrances that might provide a quicker route into the middle Cheve system.

[7] On March 1, 1991, Indiana caver, Christopher Yeager, made a fatal mistake while rappelling the 23 metres (75 ft) drop in Cheve.

J2 appears to head in the direction of Cheve Cave, with a predicted intersection beyond the tunnel collapse that stopped the team in 2003.

In the Cuicatec region, most beliefs focus on a mystical figure called Señor del Cerro ("Lord of the Hill") who dwells in Cheve and cures souls is said to reside there.

They discovered impressive jade beads, a wooden mask, in situ vessels, buried human remains and obsidian blades, believed to have been used in bloodletting ceremonies.

[16] In the spring of 1990 and 1991, three archaeological chambers in the cave were excavated by a team of speleologists and archaeologists from the Instituto Nacional de Antropología e Historia (INAH).

A decision was made to take the artifacts to the Oaxaca Regional Museum of INAH so they were not looted and to prevent further humidity damage.
