A wildfire in California over the weekend is being blamed on a gender reveal party gone wrong.

According to the SFGate, the fire has consumed more than 7,000 acres, including portions of the Sierra National Forrest, which forced rescuers in military helicopters to evacuate over 200 people on Sunday.  No deaths have been attributed to this particular wild fire, though two people were reported severely injured, with another 10 moderately injured.

The California Department of Forestry and Fire Protection put out a press release on Sunday blaming the fire on a “smoke generating pyrotechnic device used during a gender reveal party.”

It was one of several fires to break out over the holiday weekend.
