The first I've heard of dust storms was in Indiana Jones or some kind of action movies in the 80s. Then again during the Gulf War 2 when President Bush ordered to US troops to march into Baghdad. Along the way, the massive dust storms that at times would do to the US military machine that Saddam's Republican Guards could not - stopped them in their tracks until things clear up.
Then I saw this time lapse video of a actual dust storm in Phoenix, Arizona. Wow, lived in the US most of my life and I'm still learn new stuff about my own country. At the same time, the awesome power of nature really put things into perspective and just little we all are.
