Profile and sections
An oval opening of about 10 m in the Dos Ojos park, with light beams falling deep into the clear fresh water (more slanted in January). Below lies the halocline and at about -27 m a misty cloud of hydrogen sulphide with tree branches through it. The deepest point of Sac Actun (about -119 m) is here; the deep cave passages need full cave + trimix + deco.
The shaft was discovered in the 1990s by Dan Lins and Kay Wallen and explored further later, among others by Krzysztof Starnawski (2011). Human skeletons over 10,000 years old have been found. The Pit is connected to Dos Ojos and part of Sistema Sac Actun (Maya: ‘white cave’): 379.6 km surveyed, down to -119.2 m (QRSS, Jan 2025).
Practical: fee about 570 MXN, or 760 MXN combined with Dos Ojos.
- Depth and profile
- Standard -30 m; halocline -12/-20 m, H₂S cloud about -27/-30 m; deep passages (Wakulla Room, Next Generation, Noble Room to about -101 m) down to about -119 m
- Intro level
- The standard 'deep cavern' dive to about -30 m.
- Configuration
- All configurations; CCR ideal for the deep dives
- DPV: DPV-suitable
