Davst (Mongolian: Давст, salty) is a sum (district)^{[citation needed]} of Uvs Province in western Mongolia, bordering Russia in the north.^[1]

The reason it is called "salty" is that there is the biggest natural salt rock deposit in the country. The sum occupies the northern tip of Uvs Nuur which is 5 times saltier than the ocean.
