A small and picturesque town bearing the name of Damavand is beautifully situated on the southern slopes and is much used as a summer resort by the people of Tehran. There has been no eruption of the mountain in historical times and it is now regarded as virtually extinct thought some hot springs are found on its lower slopes. At the summit, there is a crater, some 300 meters across, with a profusion of yellow sulfurous rocks and pumice stones. Snow covers the crater and upper slopes in winter and spring.
