Khorasan Mountains

The mountains of Khorasan rise above the plains around Nishapur and Mashhad. The Binalud range runs northwest to southeast between these two regions, forming a high barrier within northeastern Iran. Its slopes collect water that descends towards the neighbouring valleys, contrasting with the drier land below. The ranges of northern Khorasan form a link between the mountains of Central Asia and the Alborz farther west.
