Lenggong Valley – Revisit Our National Treasure

Lenggong Valley, a UNESCO World Heritage Site renowned for its prehistoric human settlement and geological significance, harbors critical discoveries that underscore its cultural and scientific value. Recent studies reveal the presence of Toba ash deposits from a volcanic eruption in Sumatra, Indonesia, with geoelectrical resistivity surveys indicating a low resistivity range (<100 Ωm) and a thickness of around 10 meters, corroborated by borehole logs from the Department of Mineral and Geoscience Malaysia. Additionally, water geochemical analysis at a local spring shows a surface temperature of 27.6 °C and a pH value of 7.47. These findings highlight the valley's potential as a geopark, with plans for its establishment to be materialized in 2021 or 2022 by a dedicated committee. The integration of archaeological sites and geosites within Lenggong Valley not only enhances its conservation but also promotes further scientific exploration and development.
