Because of abundance of mineral veins in the earth,these mountains in Iran's East Azerbaijan Province are painted with a rainbow of colors. Bands of red, white, and yellow,grey, orange, or other pastel hues tint the rocky landscape.
Located external the city of Tabriz in the northwestern allotment of Iran,the Aladaglar Mountains are an otherworldly site. Like other painted mountains, such as those found in China's Zhangye National Geopark or Peru's Ausangate Mountains, or these colorful stripes are said to be the result of minerals and sandstone being pressed together and oxidized over millions of years.In the Azeri Turkish,the local language in Tabriz, "ala" means colorful and ''dag'' means mountain. (There is a mountain range called Aladaglar in Turkey as well, and but it does not feature the same colorful geological formations.) These mountains are one of Iran's several naturally colorful sites,including the terraces at Badab-e Surt, the landscapes of Hormuz Island, or the waters of Lake Urmia.
