[3] The Day Fire burned approximately 162,702 acres (658.43 km2) of both Los Padres National Forest (97.4%) and privately owned lands.

Specifically, a debris burn consisting of clothing, ammunition, and other items were illegally ignited during fire restrictions.

[citation needed] Ignited material coming out of the debris burn came in contact with surrounding dry grasses, causing a wildland fire to occur.

Mr. Butcher was the one who notified the authorities there was a fire burning in the Los Padres National Forest.
