Timeline & Strategic Outlook
A continuously evolving program mapping the exploration, validation, and subsurface investigation of the Yucatán Peninsula’s groundwater systems.
A Living Exploration Program
The work of RSE does not follow a rigid, linear timeline.
It evolves dynamically — guided by geological indicators, new discoveries, logistical realities, and scientific priorities.
While Phase 1 (Airborne Exploration) represents a crucial strategic component, the project is currently advancing through Phase 2 (Surface Validation) and Phase 3 (Subsurface Exploration) — building measurable progress and scientific foundation for the next expansion stage.
Where We Stand
For more than three decades, Robbie Schmittner has explored the water-filled cave systems along the Caribbean coast of the Yucatán Peninsula.
What distinguishes the present phase from previous decades is strategic intent:
We are no longer exploring only to extend cave systems. We are now targeting the five major fracture systems of the peninsula — seeking to confirm their pathways, intersections, and structural connections.
Satellite imagery, topographic mapping and geological indicators have provided hypotheses. Field exploration now serves to verify them.
Exploration Legacy
Decades of underwater exploration across the Yucatán Peninsula have revealed extensive submerged cave systems and geological formations.
Strategic Mapping
Current efforts focus on identifying and mapping the peninsula’s five major fracture systems and understanding how these structures connect underground.
Scientific Verification
Satellite imagery, geological indicators, and topographic data guide field expeditions that verify underground pathways and structural links.
2026 Operational Momentum
The year 2026 marks the transition into full-time research.
With the support of Rolex, RSE is now able to dedicate itself entirely to the project — eliminating the need to finance exploration through external employment.
Targeted Exploration
Focused exploration within the Sac Actun cave system.
Mapping Projects
Mapping of Grutas de Xpukil (CRF) and Grutas de Calcehtok (CSS).
Fracture System Research
Investigation of Río Hondo, Akumal and Holbox fracture systems.
Connection Investigation
Systematic search for connections between Koox Baal and Sac Actun.
Environmental Research
Surface and subsurface investigations within the Sian Ka’an Biosphere Reserve.
Scientific Collaboration
Joint water analyses with Friedrich-Schiller-University Jena.
Exploration Expansion
Expansion of exploration efforts toward Veracruz.
Geological Investigation
Research between the Ring of Cenotes and Sierrita de Ticul.
Phenomena Study
Investigation of the mysterious “Xuches” phenomenon.
This operational rhythm will continue throughout the year.
Strategic Goals 2026
- Confirm structural connections between major cave systems
- Expand Sac Actun toward renewed global length leadership
- Advance verification of the hypothesized convergence of Río Hondo, Sierrita de Ticul and Holbox fracture systems beneath Sian Ka’an
- Intensify hydrochemical and isotopic analysis in collaboration with FSU Jena
- Host a scientific symposium at Friedrich-Schiller-University Jena at the end of 2026
Why Phase 1 Matters
Airborne geophysical exploration remains the strategic multiplier of the project, enabling large-scale detection of subsurface structures across the Yucatán Peninsula.
Airborne geophysical exploration remains the strategic multiplier of the research program. By enabling large-scale detection of subsurface structures, it provides the spatial framework required to understand how groundwater moves through the fractured limestone systems of the Yucatán Peninsula.
However, the implementation of airborne investigations requires substantial technological resources and operational investment.
For this reason, RSE is currently building verified scientific progress through ground and subsurface research. These investigations strengthen the scientific foundation of the project while increasing the credibility and funding viability required for full Phase 1 implementation.
Looking Forward
As structural connections are confirmed within Mexico, research will gradually expand toward Guatemala and Belize — reflecting the transnational nature of the aquifer system.
The project grows in concentric circles:
From verified fractures → to regional systems → to a peninsula-wide hydrological understanding.
This is not a static expedition.
It is a continuously unfolding scientific mission.
