DENVER — Radar at 10 p.m. Wednesday detected dozens of lightning strikes within a 30-minute time frame during the Metallica concert at Sports Authority Field at Mile High.

Red bolts represent positive strikes versus the negative yellow bolts. Positive strikes occur less frequently than negative strikes, but they are far more deadly.

It was a smart decision to evacuate the infield of the stadium with this kind of thunderstorm present.
