This peak is located in the middle of the Alborz range and the mountain is located near the southern coast of the Caspian Sea, in Damavand county, Tehran Province, 66 kilometres (41 miles) northeast of the city of Tehran.
Mount Damavand first erupted in the Pleistocene almost 1.78 million years ago. After several known eruptions around 600,000 and 280,000 years ago, it finally erupted about 7300 years ago in the Holocene. Its steep cone is formed of ash and lava flows that are mainly made of trachyte, andesite and basalt. The Quaternary lavas are directly located on the Jurassic sediments. The volcano is crowned by a small crater with sulfuric deposits. There are also fumaroles, hot springs, and mineral deposits of travertine. Mount Damavand could be considered as a potentially active volcano, since there are fumaroles near the summit crater emitting sulfur, which were known to be active on July 6, 2007.
There are at least 16 known routes to the summit, with varying levels of difficulty. Some of them are very dangerous and require rock climbing. The most popular route is the Southern Route which has step stamps and a camp midway called Bargah Sevom Camp/Shelter at 4220 m (about 13,845 ft). The longest route is the Northeastern and it takes two whole days to reach the summit starting from downhill village of Nāndal and a night stay at Takht-e Fereydoun (elevation 4300 m - about 13,000 ft), a two-story shelter. The western route is famous for its sunset view. Sīmorgh shelter in this route at 4100 m (about 13,500 ft) is a newly constructed shelter with two stories. There is a frozen waterfall/Icefall (Persian name Ābshār Yakhī) about 12 m tall and the elevation of 5100 m is the highest fall in Iran and Middle East.
Damavand rivers and slopes are famous for the beautiful Brown Trout (Salmo trutta), Red Sheep (Ovis orientalis), Wild Goats (Capra aegagrus), and many singing native and migratory birds. Persian leopard (Panthera pardus saxicolor) and Syrian brown bear (Ursus arctos syriacus) live in this region. Some smaller mammals are snow vole (Chionomys nivalis), mouse-like hamster (Calomyscus bailwardi) and Afghan pika (Ochoton rufescens).
The very attractive and unreachable Caspian snowcock (Tetragallus caspius) lives at high altitudes. Golden eagle (Aquila chrysaetos) breeds in this area. Griffon vultures (Gyps fulvus) are common. Chukar partridge (Alectoris chukar) has a high population and nests between stone and shrubs. Red-fronted serin (Serinus pusillus), linnet (Carduelis cannabina), snow finch (Montifringilla nivalis), rock sparrow (Petronia petronia), rock bunting (Emberiza cia) and horned lark (Eremophila alpestris) are native; in winter they come to the lower hill sides. In each spring wheatear (Oenanthe oenanthe), rock thrush (Monticola saxatilis), and nightingale (Luscinia megarhynchos) come from Africa for breeding. Grey-necked bunting (Emberiza buchanani), black-headed bunting (Emberiza melanocephala) and common rosefinch (Carpodacus erythrinus) come from India.
Reptiles and Amphibians
Lots of marsh frogs (Rana ridibunda) lives in Lar riversides. Meadow viper (Vipera ursinii), blunt-nosed viper (Macrovipera lebetina), Iranian valley viper (Vipera latifii) and Caucasian agama (Laudakia caucasia) are among the reptiles of this mountainous region.
In the southern slope of Damavand, there are remnants of Wild Pistachia Tree (Pistacia atlantica) ; In its riversides different kind of Salix trees like Willow (Salix acomphylla) and Oleaster (Elaeagnus angustifolia) are found . Greek Juniper (Juniperus excelsa) is common all over the higher altitudes. In Northern slopes, because of higher humidity there are wild oak, beech and hazel trees like: Persian Oak (Quercus macranthera), Eastern Hornbean (Carpinus orientalis), and Oriental beech (Fagus orientalis). There are also many beautiful wild flowers like: Mountain Tulip (Tulipa montana) and Stone cress (Aethionema grandiflorum). In higher altitudes, shrubs tend to be sphere and cushion like, examples are : Astragalus species (like Astragalus microcephalus), Mountain Sainfoin (Onobrychis cornuta) and Prickly (Acantholimon erinaceum) ; Different kind of grasses between them, complete this alpine scene .
Damavand has been frequently climbed.Traditionally, the Iranian was opposed to the conquest of the mountain. The climb is long, but not difficult or dangerous. Loose stone and small ribs of rock have to be clambers over, at higher levels, if the accent in early summer, expanses of snow must be corset to the crater at the top. Because of its great height and isolation, the view from Damavand is very extensive; a vast panorama of mountains, valley and desert covering many handed of square Kilometers. All around are other peaks of the alborz range, sweeping down in the north to the humid Caspian plain and in the south descending to the deserts of central of iran
