ROCK ART IN DANGER

Rock art in danger sounds dramatic, nevertheless it is not an overstatement. During the last hundred years different kinds of destructions have never been so rapid and extensive. It is urgent to record as much as possible, because in the next 50-100 years a large part of the cultural heritage all over the world will have disappeared.

Through the effect of various natural phenomena, such as freeze/thaw which fragment the surfaces, exposure to sun and wind and the effect of lichens and moss. Changes of the environment created by man (environmental pollution) also have a detrimental impact. Major factors accelerating the weathering are acid rain, humic acid created in newly planted commercially managed forests and environmentally caused changes of the vegetation on the surface of the rocks.

The environmental debate of the late 1980s influenced rock art research decisively. The attention was focused on the already established problem of weathering, and Tanums Hällristningsmuseum Underslös decided to change its course and to employ the experience from many years of documentation work on a systematic re-documentation of entire areas of rock carvings.

The Museum publishes a series called Documentation and Registration of Rock Art in Tanum. These publications will describe the work on geographically demarcated fields of carvings as the work on each of these is completed.
