Sodom and Gomorah: all its soil burned out by sulphur and salt, unsown and unfruitful, without a blade of grass, like the catastrophe of Sodom and Gomorrah, Admah and Zeboiim, which the Lord overthrew in his furious wrath— they and all the nations will ask, “Why has the Lord dealt thus with this land? Why this great outburst of wrath?”" -Deuteronomy 29:22-23 (NABRE)
Sodom & Gomorrah The extremely high burning temperatures created a multi-shaded layering of ash that was formed by thermal ionization, caused by electrons repelling and attracting, creating a swirling effect in the remains.
Archeological evidence of Sodom and Gomorrah found at these sites. End Genesis 18 and beginning of 19 is where I am reading this morning. There are many photos of the brimstone and sulphur. There are photos of the round balls unlike any found elsewhere on the earth.
