The picture is my answer (Sodom was close to the dead sea... Lot's was drowned in it)

Ok thoughts on this story. Rather than a story of punishment it's perhaps a story of cause and effect. Her sorrow over her home caused her eventual death, pillar of salt because tears are salty?

Sodom actually erupted in flames when a natural earthquake released natural gas deposits which exploded. The pillar ofd saul had more to do with the grology of the area, which had a lot of salt pillars from where ancient seas receded.

Kate always does a great job!

The only thing I could think about while listening to her was that she might have a great voice for voice overs for animation or cartoons.
