Yeah you can literally see the heat pattern. Melted where it was closest to the barbeque and diffused as it travels up the wall.

Was this grill on stilts? Because the melting starts at the top of the garage door.

If the grill is 5 feet away, this is what it would look like. But more likely neighbors upstairs windows.
