Abstract
Twyfelfontein, a World Heritage Site , which lies in a tributary valley of the Huab River in north western Namibia, is located in an area with Jurassic Etjo Sandstones . These rocks are covered in desert varnish and it is into this material that the famous rock art has been engraved. A discussion is provided of the various ways in which such varnish can develop.
