Kuuchi T’uuchtaj Cave System – Cozumel Cave Exploration
Kuuchi T’uuchtaj is located deep in the jungle of Cozumel in the central part of the island. The Kuuchi T’uuchtaj cave system was first discovered in the late 2010s on the island of Cozumel. The first cave diver to enter the system and begin exploration was Rob Neto. During the initial exploration dives, Rob led a team of divers into the cave and discovered several passages accessible through Cenote El Poso, which serves as the primary entry point to the system.
Cenote Entrances
During exploration of the area surrounding Cenote El Poso, another nearby cenote was found to connect to the cave system through underground passages. This second entrance has been named Cenote Los Caballos.
The name Cenote El Poso was chosen because the entrance resembles a well, while Cenote Los Caballos was named after horse manure discovered along the jungle trails surrounding the cenote.
Exploration of the Cave
The discovery of Kuuchi T’uuchtaj marked the beginning of a new phase of cave exploration beneath the jungle of Cozumel. The unusual conditions inside the cave, combined with the challenge of pushing exploration through low sidemount passages, made exploration slow and deliberate. Efforts to extend the exploration line continue as divers attempt to determine whether additional passages exist beyond the current end of the surveyed line.
Exploration Notes
The first exploration dives into the Kuuchi T’uuchtaj cave system were conducted by a team of cave divers investigating cenotes located in the jungle interior of Cozumel. These dives revealed several passages extending from Cenote El Poso and eventually led to the discovery of a connection to Cenote Los Caballos.
Exploration of the main passage has currently reached approximately 1200 feet (about 366 meters) from the entrance. The end of the exploration line currently terminates in a low sidemount passage, where additional exploration will eventually continue.
The discovery and exploration of caves beneath the jungle of Cozumel, including Kuuchi T’uuchtaj, are described in greater detail in Rob Neto’s book Beneath the Jungle of Cozumel.
Unique Cave Conditions
Conditions inside the Kuuchi T’uuchtaj cave system are unlike those found in any other known cave on Cozumel. The cave walls, ceiling, and floor are covered with organic material that is extremely delicate and easily disturbed. Even small movements through the passageways can suspend this material into the water column. In some areas the organic matter appears as thin white layers that resemble delicate sheets of paper.
Because warning signs in the jungle above the cave caution that the water below is contaminated, and due to the unusual organic material found throughout the cave, the system was named Kuuchi T’uuchtaj, a Mayan phrase meaning toilet.
Geological Context
Like other caves beneath Cozumel, Kuuchi T’uuchtaj formed within the island’s limestone bedrock through karst dissolution. These caves originally developed when sea levels were lower and the passages were dry. As sea levels rose following the last ice age, the caves flooded, creating the submerged cave systems that exist beneath the island today.
Although individual caves may appear isolated, they all formed through the same geological processes that shaped the underground landscape of Cozumel.
