Mount Bolshoye Bogdo

Bolshoye Bogdo rises 149 metres above a plain that is itself below sea level, which makes it the only significant relief in the whole Caspian depression and visible from a great distance across flat salt steppe. It is being pushed up by the salt dome beneath it and is still rising a few millimetres a year. The rock is Triassic red sandstone and clay, weathered into hollows and cavities on the south-west face that the wind sounds through, which is the origin of stories about the mountain singing. Kalmyk Buddhist tradition holds it sacred, and it is said to have been consecrated by a lama; offerings are still left. The fossils in its Triassic beds were among the first described from the region. It is inside a strict reserve, so the ascent is on a marked boardwalk route with a guide, and leaving it is not permitted. Snakes, including vipers, are common.
