On Sunday, hundreds of storm chasers created this touching tribute to Bill Paxton.
Storm chasers and spotters created this massive tribute by marking GPS coordinates, dot-by-dot, to fill in Bill's initials, B.P. on a weather map used to track tornadoes.
Paxton starred in the 1996 film "Twister" as a meteorologist and storm chaser. The film put the spotlight on the vital role of storm chasers and meteorologists.
Paxton died on Saturday at the age of 61, due to complications following heart surgery.
