      Yellow map or world map lichen is frequently used in lichenometry, a geobotanical technique employed to estimate the age of exposure of a rock surface. Since <em>Rhizocarpon geographicum</em> quickly colonizes newly-exposed rock surfaces and has a known rate of growth, geologists can, for example, examine glacially-deposited rocks and determine the rate of glacial retreat. For an excellent introduction to lichenometry, read Lichens, Lichenometry and Global Warming, a short and well-illustrated paper by Richard Aston in the September 2004 issue of <em>Microbiologist</em>. 10/9/05
