Thursday afternoon firefighters stopped the spread of the Grant Fire after it burned 74 acres about 15 miles southeast of Sacramento, California. The blaze was reported at 5:44 p.m. 4 miles northwest of Rancho Murieta just west of Scott Road. CAL FIRE reports that one outbuilding was destroyed.
Firefighters worked throughout Thursday night patrolling and building containment lines. On Friday they will continue mopping up hot spots and smoldering areas within oak groves and strengthening containment lines.
Your aerial photograph tends to suggest that the fire erupted around that group of buildings. Someone burning trash, perhaps?
