This is the shocking moment a gender-reveal party stunt explosion sparked a huge wildfire that eventually spread over more than 45,000 acres.
Extraordinary footage, released by the US Forest Services, shows how one gunshot started the April 2017 Sawmill Fire that stretched across southern Arizona.
The video was filmed by a witness at a gender-reveal party, where parents-to-be were telling their guests if they were expecting a boy or a girl.
Dennis Dickey, of Arizona, had planned on revealing that his wife was expecting a son by shooting a target filled with a colourful substance.
But the target shot by Dickey, a Border Patrol agent who was off-duty at the time, also contained tannerite, a highly explosive substance, NBC News reported.
The video shows a target on dry grass, before the gunshot hits and sparks a fire.
The Sawmill fire went on to burn nearly 47,000 acres, including swathes of a national forest, and caused roughly £6.2 million ($8 million) in damages.
The April 2017 fire also required approximately 800 firefighters to help control.
According to Tuscon.com, 37-year-old Dickey pleaded guilty to causing the fire and was sentenced to five years’ probation.
