context_page_description: Korea's National Treasure No. 285, the Bangudae Petroglyphs, are located mainly on flat vertical rock faces around 8m wide and around 5m high on steep cliffs on the riverside of the Daegokcheon stream, a branch of the Taehwa River, which runs eastward and joins the East Sea at Ulsan. The surrounding ten rock faces have a small number of engravings as well. The rocks consist of shale and hornfels oriented toward the north and they shine for a while at sunset. As an overhanging cliff they are in the structure of a rock shelter.
context_section_description: The Sayeon Dam, built from 1962 to 1965 and expanded between 1999 and 2002, helps supply Ulsan with drinking water but has caused the rocks on which the petroglyphs are carved to be flooded for about eight months of every year. This periodic flooding raises concerns of erosion and water damage of the rock-art motifs, which are considered to be masterpieces of prehistoric art and an invaluable source of prehistoric information. The government of Korea is considering building a polycarbonate “dam” to protect the rock faces.
