This immersive field trip explores the geological, climatic, and cultural richness of Meghalaya, with a special focus on the Mawmluh Cave, India’s only Quaternary Global Boundary Stratotype Section and Point (GSSP). This site marks a major global climatic shift around 4,200 years ago, making it a crucial archive for paleoclimatic and monsoon variability studies. The trip also explores the Shillong Plateau, a tectonically active block offering insights into crustal deformation, uplift processes, and the influence of structures like the Dawki Fault on river systems such as the Brahmaputra. Beyond geology, the region’s caves, landscapes, and archaeological sites provide evidence of prehistoric habitation, megalithic cultures, and indigenous knowledge systems. Participants will also witness living root bridges, remarkable examples of bio-engineering by the Khasi and Jaintia communities, which represent a sustainable symbiosis between human ingenuity and natural resources.
