Human bones remain inside the Liaunan cave and rock shelters in Barangay Caub in Del Carmen town, Siargao Island on November 30, 2020. In a research study released in January 2019, the National Museum of the Philippines and the Archaeology Studies Program of the University of the Philippines-Diliman confirmed the site as an ancient burial ground. The bones were displaced due to the rampant treasure hunting activities in the area. MindaNews photo by ROEL N. CATOTO
