... but it sure looks like it. Here's the view from the 30th floor of 5900 Wilshire -- also known as the Variety Building -- in the Miracle Mile. According to the L.A. Times, this huge plume of smoke is the result of a brush fire in the Angeles National Forest near Highway 39.
The paper reports that campgrounds have now been evacuated in the area. More:
The fire broke out about 4:40 p.m. along San Gabriel Canyon Road near Morris Dam. KABC Channel 7 showed firefighters battling tall flames on a ridge off Highway 39, which is closed in both directions.
The fire burned about 25 acres but was growing. Firefighters and inmate crews were on the scene, and air support was making water drops, officials said.
Black smoke could be seen from around the San Gabriel Valley.
And, of course, from as far away as here in the Miracle Mile, where we've spotted several brush fires this summer, thanks to our vantage point up here.
