Huge chunk of compacted snow hit my car

Denver CO

Description

At around 1030 am I was going westbound on I6 between Sheridan and Wadsworth when 2 huge chunks of ice flew off of the roof of a4runner(?) Going eastbound. My windshield and front lights were crushed. I tried going back later and looked for what hit me but couldn't find it. That's why I'm assuming it was ice. If you saw anything please, please email me. And please always take care of the snow on the roof of your car....
