Newly released video shows a baby gender reveal stunt that the U.S. Forest Service says was responsible for a massive wildfire.

The video, shot in April, shows the explosion that started the Sawmill Fire near Tucson, Arizona.

A figure in the video, which has been blocked out by the U.S. Forest Service, runs over to the burning area, and a voice off-camera can be heard shouting, “Start packing up!”

The fire burned nearly 47,000 acres of state land in a little more than a week.

No injuries were reported as a result of the fire and no homes were lost, but the fire did burn timber, trees, brush, and grass throughout Coronado National Forest.

U.S. Border Patrol agent Dennis Dickey pleaded guilty to starting a fire without a permit. Dickey shot a target packed with the explosive Tannerite and a blue powder.

He appeared in federal court in October and was sentenced to pay $100,000 up front and $500 every month for the next 20 years.

He also agreed to conduct a public service announcement with the U.S. Forest Service about the cause of the fire.
