My initial search results let me to a biblical website about Sodom, most likely due to the fact that it is located near the dead sea, which is known for its extremely high salt content. It also led me to the wikipedia page for the cities of Sodom and Gomorrah.

Other results brought me to the wikipedia page for Lot's wife, also relating to Sodom.

A further look into the Lot's Wife wikipedia page lead me to images of salt pillars, including the image I initially searched

We also get the obvious result, salt, which again leads back to the dead sea.
