Preservation Concerns
Built from 1962 to 1965 and expanded between 1999 and 2002, the creation of the Sayeon Dam helps supply Ulsan with drinking water but the rocks on which the petroglyphs are carved are now periodically flooded for about eight months every year. The rock-art motifs are considered to be masterpieces of prehistoric art and an invaluable resource of prehistoric information. Historic and ongoing periodic flooding raises concerns of erosion and water damage. In 2002, an extensive study on the Bangudae and Cheonjeon-ni was undertaken by various institutions led by Ulsan university museum. Not surprisingly the study suggests that the Bangudae Petroglyphs must be better preserved.
