Summary[edit]

Description
English: Desert varnish can be differentiated from regular staining and streaking by its thick coating and sheen. Although still not fully understood, microbiologic activity and wind-blown clay seem to be major factors in the creation of the unusually high amounts of manganese and iron oxides found within this varnish. These minerals, in varying concentrations, are responsible for both the distinctive shininess, and also the various colors of desert varnish. NPS Photo/Jonathan Fortner
