Connection of "Mother of All Cenotes" to "Koox Baal"
Facebook · 2025-06-23
Yesterday, Phillip Lehman, Patrick Widmann, Rosso Rivera, and I successfully connected the "Mother of All Cenotes" system with the "Koox Baal" system. To achieve this, we had to find a navigable passage between the two systems, which are approximately 1.5 km apart as the crow flies. And we did! To bridge the gap and establish the connection, we laid over 8 km of guideline. Yesterday’s dive lasted 425 minutes, during which we used Sidewinder rebreathers, Seacraft scooters, and mnemo mapping tools to navigate and document the newly linked sections. With this connection, the total length of the Koox Baal system has now reached 123 km. This marks a significant milestone in the exploration of the Yucatán’s vast underwater cave networks.
