The University of Guyana (UG) proudly announces the successful return of an international team of speleologists and researchers from the “Beyond the Falls” project, a high-level scientific expedition focused on advancing understanding of Guyana’s unique geological landscapes. Representing both the University and the nation was Geography undergraduate Rahul Changa, Vice-President of the University of Guyana Geographical Society, whose participation reflects UG’s growing footprint in global research initiatives.

The expedition was conducted at Kumerau Falls along the Kurupung River in Region Seven, where the team investigated the speleogenetic processes responsible for the formation of one of the largest known waterfall overhangs globally. This work positions Guyana as a critical site for advancing research in quartzarenite cave systems and tropical geomorphology.

During the mission, the team successfully located, explored, surveyed, and documented a cave system developed within the quartzarenites of the Roraima Supergroup, first identified in 1976 by British speleologists. This cave is of particular scientific interest due to the presence of silica speleothems and a distinct cave fauna. In a significant breakthrough, the team also discovered and documented a second cave system measuring approximately 200 metres in length.

Extensive data collection was undertaken, including chemical analysis of water samples and lithological investigations. These findings will support the development of a detailed speleogenetic model explaining the formation of the massive overhang that characterises Kumerau Falls. The results are expected to contribute to both academic research and conservation planning within the Guiana Shield.

Mr. Changa’s involvement highlights the University of Guyana’s commitment to experiential learning and international research engagement. As a student leader and emerging geographer, his participation demonstrates the calibre of UG students and their capacity to contribute meaningfully to complex scientific investigations on a global stage.

The project was coordinated by the La Venta Esplorazioni Geografiche Association, in close collaboration with the Department of Geography at the University of Guyana and the Department of Geosciences at the University of Padua, Italy. The University extends sincere appreciation to La Venta for its leadership and for facilitating meaningful opportunities for student involvement in high-impact research.

The expedition was supported by the Guyana Tourism Authority and conducted under the supervision of the Environmental Protection Agency, ensuring adherence to national environmental standards. Additional support was provided by the Rolex Perpetual Planet Initiative and The Explorers Club, whose continued investment in scientific exploration enables critical discoveries in remote and understudied environments.

The University of Guyana remains committed to strengthening its role in international research partnerships while advancing knowledge and preservation of Guyana’s natural heritage. A comprehensive technical report based on the findings is currently being prepared and will inform future conservation efforts at this extraordinary site.
