Lichen on Mount Etna
October 15, 2012
As shown above on this July 26, 2012 photo of Mount Etna (Sicily), Italy, lichen and grasses are starting to re-grow on the volcano's southern summit face. Mount Etna's last major eruption occurred in 2001. However, Etna is still a very active volcano, but lichen can live, grow and re-seed even on a barren lava field. They're able to thrive in some of the most uninviting places on our planet and can tolerate huge swings in temperature and moisture conditions. If conditions are too stressful, though, they'll go into a dormant state. Photo taken at approximately 6,000 ft (1,829 m) on the south face of Mount Etna.
