LOS ANGELES (CBSLA.com/AP) — Firefighters are making significant progress against a fire that scorched nearly 61 square miles in northern Los Angeles County.

The fire command says the blaze is 85 percent contained Friday, eight days after it broke out in a semi-rural area of suburban Santa Clarita and spread into the mountainous Angeles National Forest.

Firefighters continue to work on cutting a line around the fire, perform mop-up activities and withdraw excess equipment.

The east side is in a deep drainage and officials caution that if winds align with that feature the fire potentially could enter heavy vegetation.
