Area of Sodom and Gomorrah

According to the Bible Map of Canaan in Old Testament times, the area of Sodom and Gomorrah is situated along the southern/eastern cost of the Dead Sea. The Cities were destroyed for the sin of its inhabitants. The males were practising their lusts on men in preference to women.

The whole tract on the sides of the Dead Sea, where the Cities were situated, is covered with sulphureous salts and it is deadly to animal and plant life. Perhaps this was a Sign of the utter destruction of these Cities as refered to in the Qur'an;

"For we are going to bring down on the people of this township a Punishment from heaven, because they have been wickedly rebellious." And We have left thereof an evident Sign, for any people who (care to) understand.
[Qur'an 29:34-35]
