Abstract

The exposed surfaces of stone artifacts from the Security Cove site, Alaska, were altered by the mechanical-chemical activity of crustose lichens. This factor should be considered in patination studies carried out in regions where lichens are known to occur. The activity of lichens and the resultant effect on artifact surfaces is discussed and illustrated in two figures.
