Lichenometry dating

Have you ever noticed an old stone wall and wondered how long it has been there? If there is lichen growing on the wall, the lichen has most likely been living there since the time the wall was made, so if you could figure out how old the lichen is then you could deduce the age of the wall. Geologies use this method, called lichenometry , and other methods to establish dates and temporal sequences as they seek to construct a history from the available evidence. In this geology science project, you will use lichenometry as a method for dating relatively recent events in your area, such as the formation of a manmade or geological feature or a disturbance in your area for example, the building of a stone wall, the occurrence of a rock slide, or when a road was cut.
