Band-e Amir National Park (Persian: بند امیر) Afghanistan established its first national park on April 22, 2009, to promote and protect the natural beauty of a series of intensely blue lakes created by natural dams high in the Hindu Kush. Band-e-Amir is a chain of six lakes in the mountainous desert of central Afghanistan. The lakes formed from mineral-rich water that seeped out of faults and cracks in the rocky landscape. Over time, the water deposited layers of hardened mineral (travertine) that built up into walls that now contain the water. According to the Wildlife Conservation Society, who helped the Afghan government set up the park, Band-e-Amir is one of the few travertine systems in the world. They were created by the carbon dioxide rich water oozing out of the faults and fractures to deposit calcium carbonate precipitate in the form of travertine walls that today store the water of these lakes. Band-e Amir is one of the few rare natural lakes in the world which are created by travertine systems. The site of Band-e Amir has been described as Afghanistan's Grand Canyon, and draws thousands of tourists a year. The river is part of the system of the Balkh River. From Wikipedia
