Eight kilometres south of Kyzyl Ravine is Sor Tuzbair*, a salt marsh stretching 15km along the edge of the Western Chink Ustyurt. Along with Boszhira, it’s one of Mangystau’s most recognisable and visited natural landscapes.

The most defining feature of Sor Tuzbair is its vast expanse of salt flats backed by waterworn, chalk-white cliffs. Until at least a few million years ago, the area was part of the Paratethys Sea. If you poke around the slopes and rock faces, you’ll find belemnite and ammonite shells, and numerous other fossilised marine organisms. There are even shark teeth to discover, such as from the Parotodus mangyshlakensis, which is an extinct genus of the mackerel shark and highly sought after by fossil collectors.

From the Western Chink Ustyurt – which extends from the Karynzharyk Depression in the south to northern Kaydak Bay – there are three dirt roads leading to the salt marsh. The closest is near to Kertt Spring and the other two, in the Bagda and Baurbas Ravines, are 15+ kilometres to the east. Don’t venture onto the salt flats with your car, unless you’re an experienced off-roader, as the area is prone to flash flooding and it’s easy to get stuck in sections of thick, salty mud.

* In Kazakh, and several other Turkic languages, ‘sor’ means a salt pan or a shallow, salty lake.
