This paper intends to present the petroglyph site of Zamthang (Zam thang) located in the Lungnak (Lung nag) valley of Zan- skar (bZangs dkar), Kargil district of Ladakh (La dwags), Jammu and Kashmir, India. It will show that this site can be consid- ered as the most important one from about 20 known rock art sites in Zanskar. The paper starts with a brief history of the awareness and knowledge of the country’s rock art heritage and its main actors be- fore concentrating on the history of that particular site documenta- tion itself. The problems and prospects of rock art conservation and development in this area will also be briefly discussed. Subsequently, the paper attempts a full description of the site’s setting, its content and the chronology of its survey and documentation. The current condition of the site as well as the prospects for its enhancement and protection will also be presented. A brief comparative overview of some of the major and most relevant elements of its content will be discussed and aim at defining a timeframe. To conclude, the neigh- bouring rock art sites as well as other linked historical remains will briefly be presented together with some geographical specifications with a view to highlight the anthropological potential of the area and the much-required interdisciplinary and systematic study.
