Mount Erciyes, is a massive extinguished volcano located 25 km south of Kayseri, 85km east of Cappadocia. Erciyes is the highest mountain in central Anatolia, with its altitude 3,917 metres. The volcano is heavily eroded, but may have erupted as recently as 253 BC, as may be depicted on Roman era coins which is found in Kayseri and Cappadocia. Strabo wrote that in his time the summit was never free from snow and that those few who ascended it could see both the Black Sea and the Mediterranean.
