evidence: The southern coast of the Kerch peninsula is washed by the Black Sea and the Bay of Feodosia, to the east as a natural border serves the Strait of Kerch, while the northern shores are part of the coastline of the Sea of Azov, Kazantip Bay, and Bay of Arabat. Away to the northwest from the peninsula runs another isthmus known as the Arabat Spit (locally Arabat arrow) which separates Sivash (the Rotten Sea) from Azov Sea. Other prominent features of the peninsula are Mount Mithridat located in the east at the shores of the Strait of Kerch and the Ararat Mountain (175 metres (574 ft)) located just west of the Kerch city, both of which are part of the northeastern elevated region. At the southeastern portion of peninsula are located mountains Sosman and Kharuchu-Oba. The highest mountain on the peninsula is Pikhbopai that is part of the Mithridat crest and 189 metres (620 ft) tall. The Kerch Peninsula, as well as surrounding areas such as Azerbaijan, Iran, Russia, and the Caspian Sea region (which encompasses the Caucasus and Central Asia) are home to many mud volcanoes. These mud volcanoes are important for the region's oil industry.[1][2][3]
