Lichenometry is one of many techniques now available for estimating the elapsed time since the exposure of a substratum. Its advantages include an ability to date surfaces during the last 500 years, a time interval in which radiocarbon dating is least efficient, and provides a quick, cheap, and relatively accurate date for a substratum.
