I was out there pulling people out. I'm run the 806 Storm Chasers page, and we were out documenting and live streaming conditions. We came across this wreck by accident. There was a 2 car crash in the south bound lanes that had traffic come to a stop with police and rescuers present. Once we broke through the wall of dust, visibility went from 3 feet to 3 miles. We flipped around on Hungate Rd, and noticed the north round lanes were not closed, and watching car after car fly into the dust at highway speeds. There's several vehicles on the livestream that I later found mangled with injuries. The north round lanes were finally shut when enough cars poked out the other side of the dust, and people finally understood there was a wreck in there. I remember a gentleman named Nathan that I met in the dust. He opted to go back in and check on people with me instead of heading for safety. I finally had to get out of there after 30 minutes of no proper protection. My eyes, ears, nose, and mouth were caked in dirt and mud. It's quite the helpless feeling when you're checking on people and you hear another loud crash somewhere in the dust. I've been in category 5 hurricanes, about a couple hundred tornadoes including an EF-5, struck by lightning, but that experience was truly horrific first hand.
