I’ve been keeping a wary eye on the fires in Colorado, including one north of me, one south, and one way too close for comfort: the Flagstaff fire. This one crept over the foothills just southwest of Boulder and was pretty threatening there for a day or so, but it looks to be under much better control now, and firefighters think they’ll have it fully contained very soon. It was started by lightning, which is ironic since a few rain showers helped keep the fire under control as well.
Boulderite Dustin Henderlong took some amazing time lapse footage of the fire showing how much smoke was pouring out. The shots at night are, well, lovely, as much as I hate to say it.
The footage runs from 3:00 p.m. local time on Tuesday June 26 to 10:00 a.m. on Thursday. We’ve had some "spot" fires caused by more lightning strikes since then, but they’ve been taken care of quickly and efficiently by the amazing firefighting force deployed.
Not long after the fires started I was able to see the plume of smoke and water vapor from my house, nearly 10 km away:
As I mentioned in an earlier post, the thick parts of the smoke are red and the outer parts blue. A lot of that is due to the way light interacts with the particles in the smoke; blue light gets easily scattered away near the edges, but red light penetrates more deeply.
Just hours after the fire started, the plume had two pieces: a darker smoky part blowing east, and a lighter, bluer one that went up higher and got caught in more northerly winds. That blew it over my house, and I took this shot facing north, away from the fire – indicating just how far-reaching this was:
