RENO — Officials say rain helped quell flames and firefighters have 40 percent containment of a wildfire burning on Seven Lakes Mountain near the Rancho Haven community about 45 miles northwest of Reno.
Sierra Front fire managers say the Red Rock Fire covers more than 11 square miles of grass, brush, juniper and pinyon pine in steep and rocky terrain.
No injuries are reported and no structures have been damaged.
More than 220 firefighters, including Truckee Meadows, federal Bureau of Land Management and Sierra Front crews are protecting about 50 homes south of the 5,450-acre fire.
The fire was reported Monday afternoon east of U.S. Highway 395 in Lassen County, Calif., and quickly spread east across the California-Nevada state line into Washoe County.
Rain was reported early Wednesday. Containment is expected Friday.
