Azerbaijan is nearly surrounded by mountains. The Greater Caucasus range lies to the northeast along the border with Russia and extends into northeastern Azerbaijan and runs southeast to the Absheron Peninsula. The Lesser Caucasus range lies to the west along the border with Armenia, and the Talysh Mountains lies to the south along the border with Iran. There are mineral springs and very active mud volcanoes in Kobustan Mountain, which is situated near Baku. The highest peaks in the Republic of Azerbaijan are situated in the Greater Caucasus, the Lesser Caucasus and Talysh mountain systems. The highest peak in the Republic of Azerbaijan is Bazarduzu (4,466 metres or 14,652 feet).[1]
