In November 2009, the UTD Cave Diving Team explored the cenote known as “The Pit” located in Tulum, Mexico; part of the Yucatan Peninsula.
The Pit is comprised of break-down rooms with 100’ / 30m high ceilings and walls that are 100’+ /30m+ away from the line. These rooms are actually more like massive chambers that are connected by narrow, tight passageways (known as restrictions) which then open up to even more chambers of enormous proportions. The entirety of “the Pit” is a collection of these gargantuan rooms and restrictions linking them together.
The mission of the UTD Cave Diving Team was to (1) survey “the Pit”, (2) collect data for a 3D map, and (3) ultimately document scientific data regarding the water quality and flow systems throughout the area.
In order to meet these objectives, the team worked at depths well over 300 ft / 90m, with bottom times in excess of 2.5 hours, followed by more than seven hours of decompression obligation.
