Freddie Alexander Smoke III, 27, was arrested on Saturday for investigation of recklessly causing a fire and illegally cultivating marijuana, according to the California Department of Fire and Forestry Protection.
The fire has burned 15 square kilometres of forested land and destroyed 18 structures, CalFire officials said. The fire, burning in steep terrain, was just 15 per cent contained yesterday morning.
More than 1,700 firefighters, aided by aircraft, battled the blaze in hot, dry conditions.
Still, the fire is threatening 15 homes and about 50 other structures.
