Alpine lichens (Ist of 2)

The crustose lichen Rhizocarpon geographicum has been used to calculate the age of some glacial moraine surfaces. By measuring the diameter of the largest lichens on a moraine, and by knowing how much the diameter increases each year, scientists can calculate how long the area has been free of ice cover.
