Thailand’s wildlife rangers and archaeologists have recently announced a significant discovery on the summit of Phu Khat Mountain, the highest summit of Phu Khat Wildlife Sanctuary. At 1,307 meters above sea level, the summit has now produced two newly discovered archaeological sites, just approximately 300 meters apart from one another.
The new locations, which altogether were referred to as “Pha Pang Puey,” were found during routine patrols conducted between September 4–6, 2025. Rangers noticed unusual linear cuts inscribed on reddish-brown rock faces, and some faces had patches of lighter grey coloration from lichen and weathering. Unlike natural cracks, the cuts form geometric and abstract patterns, suggesting careful human craftsmanship and pointing towards ancient rock painting traditions.
Experts indicate that the carvings resemble petroglyphs discovered last year in Ta Kueng Cave, a second site in the sanctuary, where rock art dated more than 2,000 years ago was discovered. Together, the findings reveal the secret cultural and historical riches in Thailand’s protected forest areas.
The sites were located in Yang Klon Subdistrict, Phitsanulok Province, in the confluence of Nong Haeng, Hua Pong Singtan, and Pang Pueai forests. In addition to their archaeological significance, the sites afford views of dense forest, breathtaking sunrises, and ridges of northern Thailand and are therefore both culturally and naturally significant.
According to officials, the discovery proves the twin role of the sanctuary as a vital watershed system and a repository of ancient heritage. Phu Khat has already yielded some important archaeological finds, including caves and inscriptions related to early humans. The Fine Arts Department 6th Region Office in Sukhothai was asked to supply technical support for additional surveys, with researchers hoping other sites could lie hidden in the isolated woods.
The dig of Pha Pang Puey not only increases the understanding of the region’s history but also emphasizes the way in which Thailand’s conserved wilderness is the keys to the unlocking of the untold stories of historic human life.
