Lot moved to Sodom because its location in the Jordan Plains made it seem like a fertile, attractive area - reminiscent of paradise and of Egypt -- but the Torah reminds us that this was only true before Sodom was destroyed (Genesis 13, 10).

After the destruction of Sodom, the area of the former town was completely desolate, unfit for habitation or growth and full of salt (Jeremiah 49, 18; Jeremiah 50, 40; Zephaniah 2, 9). 

Archeological ruins from Sodom were not found, but many posit that the search for remains should be concentrated at the Dead Sea area. Sodom is connected to the Hill of Salt (Mount Sodom), and is called Jebel Usdum, meaning "Mount Sodom," in Arabic.

Another opinion about the location of Sodom identifies it as being located here.
