(Armenian Masis; Turkish Büyük or Agri Dagi; Persian Koh-i-nuh), mountain, extreme eastern Turkey, near the border with Armenia and Iran. Except on the northwest, where a spur nearly 2134 m (7000 ft) high merges with a long ridge, the mountain is completely isolated, being surrounded on all other sides by elevated plains ranging from about 760 to 1370 m (about 2500 to 4500 ft) above sea level. From an elevation of about 2680 m (about 8800 ft) Ararat rises in two peaks, known as Great Ararat (5122 m/16,804 ft) and Little Ararat (3914 m/12,840 ft). Above the 4267-m (14,000-ft) level, Great Ararat is perpetually covered with snow. Vegetation, consisting for the most part of grasses, is chiefly confined to the area between about 1525 and 3355 m (about 5000 and 11,000 ft). According to the Old Testament (see Genesis 8:4), Noah's ark landed on the mountains of Ararat after the deluge. On July 2, 1840, great masses of the mountain were torn loose by a violent earthquake. The resulting avalanche buried a village and the St. Jacob's Monastery on its lower slopes producing the Ahora Gorge.
