The Sinjar Mountains (Arabic: جبل سنجار jabal Sinjār; Kurdish: Çiyayên Şengalê چیای شەنگال/شەنگار; also Shingal\Shengar Mountains) are a 100-kilometre-long (62 mi) mountain range that runs east to west, rising above the surrounding alluvial steppe plains in northwestern Iraq to an elevation of 1,463 meters (4,800 ft). The highest segment of these mountains, about 75 km (47 mi) long, lies in the Nineveh Governorate. The western and lower segment of these mountains lies in Syria and is about 25 km (16 mi) long. The city of Sinjar is just south of the range. These mountains are regarded as sacred by the Yazidis.
The Sinjar Mountains are a spectacular example of a breached anticlinal structure. These mountains consist of an asymmetrical, doubly plunging anticline, which is called the Sinjar Anticline, with a steep northern limb, gentle southern limb and a northerly vergence. The northern side of the anticline is normally faulted, which results in the repetition of the sequence of sedimentary strata exposed in it. The deeply eroded Sinjar Anticline exposes a number of sedimentary formations ranging from Late Cretaceous to Early Neogene in age. The Late Cretaceous Shiranish Formation outcrops within the middle of the Sinjar Mountains. The flanks of this mountain range consist of outward dipping strata of the Sinjar and Aliji formations (Paleocene to Early Eocene); Jaddala Formation (Middle to Late Eocene); Serikagne Formation (Early Miocene); and Jeribe Formation (Early Miocene). The Sinjar Mountains are surrounded by exposures of Middle and Late Miocene sedimentary strata
The mountain is a groundwater recharge area and should have good quality water, although away from the mountain groundwater quality is poor. Quantities are sufficient for agricultural and stock use.
Population and history
The mountains primarily served as the border frontiers of empires throughout its history; it served as a battlefield between the Assyrians and the Hittite Empire, and was later occupied by the Parthians in 538 BC. The Roman Empire in turn occupied the mountains from the Parthians in 115 AD. From 363 AD, as a result of the Byzantine–Sasanian wars, the mountains lied on the Persian side of the frontier between the two empires. This Persian influence lasted for at least two hundred years and led to the introduction of Zoroastrianism in the region. In the 4th century AD, Christian influences on the mountains became well established, with Sinjar being part of the Nestorian Christian diocese of Nusaybin. In the 6th century AD, the region was fell under Islamic rule as part of the Muslim conquests, with Christian inhabitants being allowed to practice their faith in exchange for payment of a tax. 
Since the 12th century, the area around the mountains have been mainly inhabited by Yazidis who venerate them and consider the highest to be the place where Noah's Ark settled after the biblical flood. The Yazidis have historically used the mountains as a place of refuge and escape during periods of conflict. Gertrude Bell wrote, in the 1920s: "Until a couple of years ago the Yezidis were ceaselessly at war with the Arabs and with everybody else."
Islamic State conflict
In August 2014, an estimated 40,000 to 50,000 Yazidis fled to the mountains following raids by Islamic State (IS) forces on the city of Sinjar, which fell to ISIL on August 3. The Yazidi refugees on the mountain faced what a relief worker called a "genocide" at the hands of ISIS. Stranded without water, food, shade, or medical supplies, the Yazidis had to rely on scarce supplies of water and food airdropped by American, British, Australian, and Iraqi forces. By August 10, Kurdistan Workers' Party (PKK), People's Protection Units (YPG) and Kurdish Peshmerga forces defended some 30,000 of the Yezidis by opening a corridor from the mountains into nearby Rojava, through the Cezaa and Telkocher road, and from there into Iraqi Kurdistan. Haider Sheshu commanded a militia that waged a guerilla war against ISIS. Although thousands more remained stranded on the mountain as of August 12. It has been reported that 7,000 Yazidi women were taken as slaves and over 5,000 men, women, and children were killed, some beheaded or buried alive in the foothills, as part of an effort to instill fear and to supposedly desecrate the mountain the Yazidis consider sacred. Yezidi girls allegedly raped by ISIS fighters committed suicide by jumping to their death from Mount Sinjar, as described in a witness statement.
