Sahand
Sahand (), is a massive, heavily eroded stratovolcano in East Azerbaijan Province, northwestern Iran. At , it is the highest mountain in the province of East Azerbaijan. Sahand is one of the highest mountains in Iranian Azerbaijan, in addition to being an important dormant volcano in the country. The Sahand mountains are directly south of Tabriz, the highest peak of which is Kamal at an elevation of . Approximately 17 peaks can be accounted for as being over in height. Due to the presence of a variety of flora and fauna, the Sahand mountains are known as the bride of mountains in Iran. Sahand is made chiefly of dacite and associated felsic rocks. Winter sports Sahand Ski Resort is on the northern foothills of the mountain and near the city of Tabriz. Name Iranian naval ships have been named for it including IRIS Sahand (1969), IRIS Sahand (2012), and Iranian IRIS Sahand (F-74).

Ultra Prominent Peak
An ultra-prominent peak, or ultra for short, is a mountain summit with a topographic prominence of or more; it is also called a P1500. The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. There are approximately 1,500 such peaks on Earth. Some well-known peaks, such as the Matterhorn and Eiger, are not ultras because they are connected to higher mountains by high cols and thus do not achieve enough topographic prominence. The term "ultra" originated with earth scientist Steve Fry, from his studies of the prominence of peaks in Washington (state), Washington in the 1980s. His original term was "ultra major mountain", referring to peaks with at least of prominence. Distribution Currently, over 1,500 ultras have been identified above sea level: 654 in Asia, 357 in North America, 209 in South America, 119 in Europe (including 12 in the Caucasus), 84 in Africa, 54 in Oceania, and 39 in ...

Miocene Stratovolcanoes
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and hominoids into Eurasia. During the late Miocene, the connections between the ...

Mountains Of East Azerbaijan Province
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains te ...

Landforms Of East Azerbaijan Province
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodi ...

Mountaineering In Iran
Mountaineering, mountain climbing, or alpinism is a set of outdoor activities that involves ascending mountains. Mountaineering-related activities include traditional outdoor climbing, skiing, and traversing via ferratas that have become sports in their own right. Indoor climbing, sport climbing, and bouldering are also considered variants of mountaineering by some, but are part of a wide group of mountain sports. Unlike most sports, mountaineering lacks widely applied formal rules, regulations, and governance; mountaineers adhere to a large variety of techniques and philosophies (including grading and guidebooks) when climbing mountains. Numerous local alpine clubs support mountaineers by hosting resources and social activities. A federation of alpine clubs, the International Climbing and Mountaineering Federation (UIAA), is the International Olympic Committee-recognized world organization for mountaineering and climbing. The consequences of mountaineering on the natural env ...

Stratovolcanoes Of Iran
A stratovolcano, also known as a composite volcano, is a typically conical volcano built up by many alternating layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and explosive eruptions. Some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and solidifies before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high to intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less viscous mafic magma. Extensive felsic lava flows are uncommon, but can travel as far as 8 km (5 mi). The term ''composite volcano'' is used because strata are usually mixed and uneven instead of neat layers. They are among the most common types of volcanoes; more than 700 stratovolcanoes have erupted lava during the Holocene Epoch (the last 11,700 years), and many older, now ...

Kandovan, Osku
Kandovan () is a village in Sahand Rural District of the Central District in Osku County, East Azerbaijan province, Iran. It is situated in the foothills of Mount Sahand, near the city of Osku. The village exemplifies manmade cliff dwellings which are still inhabited. The troglodyte homes, excavated inside volcanic rocks similar to dwellings in the Turkish region of Cappadocia, are locally called ''Karaan''.Hashemi, S., 2013.

Karaans were cut into non-welded ignimbrites, also called "ash-flow tuffs," of Mount Sahand. The cone form of the houses is the result of the erosion of ignimbrite layers consisting of porous, round and angular pumice together with other volcanic particles that were positioned in a grey, acidic matrix.
