The Santiago Fire has moved up into the mountains, raging through the Cleveland National Forest. The canyons are still under evacuation, but out here in the Saddleback Valley, it just looks like a really smoggy day. With yellower-than normal sunlight. It was actually cold this morning, for the first time in well over a week.

Things were just clear enough at home last night that we opened the windows for about an hour to air the place out. Then the smell of smoke started drifting in again.

Because there hasn’t been much to see since Thursday, I haven’t been taking as many photos. So instead I’ll point you to a couple of nighttime photos I found on Wikipedia’s article on all the fires. The one on the left is a view from Aliso Viejo across the valley (the Washington Mutual building at the lower left is half a block from the comic store I frequent) by Wikipedia user Bighead. The one on the right is a view from Mission Viejo by Kevin Labianco. His other photos on Flickr are worth looking at as well.

I’ve noticed people starting to speculate on terrorism as a possible cause of the fires, because it’s awfully suspicious that they’d all break out at once. Well, no, actually: it isn’t suspicious at all. Southern California is a very dry region. It rains in the winter (well, usually), then dries out in the summer. By the end of summer, the grasslands and brush are basically tinder. Then the Santa Ana winds blow in, usually in October: high speed, high temperature, low humidity. They dry things out even further, spark power lines, and once a fire has started (by arson, accident, etc.), make it spread rapidly. To make matters worse, there’s that drought I mentioned last week.

So if conditions are ideal (so to speak) for fire in one place, they’re usually ideal all over the region. We get wildfires every year, often two or three at once. They don’t get the headlines when they’re out in the wilderness, only when they encroach on cities and homes. And sometimes, when conditions are really bad, we get massive fires across the region. It’s happening now, it happened in 2003 (with the Cedar Fire being the largest), it happened in 1993 (the nearby Laguna Beach fire being only one of several).

In short, California burns regularly. People can help that process along, but it happens. Could terrorists have started some of the fires? (So far, only the Santiago Fire has been identified as arson.) Possibly. But it’s hardly the most likely explanation.

With the winds dying down, the smoke from the Santiago Fire clung loosely to the mountains most of the day. Unfortunately, smoke from the new fires down on Camp Pendleton drifted up the coast to take its place, bringing back the yellowish sunlight. Also, without the wind to clear them away, ashes left a thorough coating on anything outside. Work was somewhat calmer, with everyone (and their houses) finally accounted for. Power kept flickering throughout the afternoon, though. Between 4:30 and 5:00, something massive flared up, sending a new plume of smoke into the sky.

Orange MoonI ended up leaving the office after dark, giving me a chance to take some pictures of the orange moon (it was actually a bit past first quarter on Sunday, and it’s not quite full today*).

I also went looking for spots to take pictures of the red glow coming from the mountains. There’s a bridge near the office where I frequently take pictures of the hills, and I managed to find a spot where I could set up my mini-tripod and still have a view of the glow. There was one brighter patch which seemed to be changing shape, which I figured might actually be flames.

Mountain Glow

Afterward, I drove up to a cul-de-sac on Quail Hill which I’d discovered at lunch. I just parked my car at the end of the road, put the camera on top of it, and started trying shutter speeds.

Santiago Canyon Glow

The vantage point gave me a better sense of geography. The Irvine Spectrum area lies in the foreground, with the 4 tall office buildings (the two in the middle are under construction) and the bright neon proclaiming the movie theater. The shopping center stretches off to the right. The empty area behind them consists of undeveloped land from the former El Toro Marine Base and the hills that burned earlier this week. The clusters of lights about 1/3 of the way up are, I think, Foothill Ranch. That places the glowing area in Santiago Canyon.

Even though some of the houses up on Quail Hill seemed to still be under construction, they had an efficient neighborhood watch going. I must have been there only 3 minutes before a van pulled up into a nearby space. A guy stepped out. No labels, no uniform. I said something along the lines of, “Hello, I’m taking pictures of the glow from Saddleback.” He said, “It’s still going, huh?” “Yeah.” I muttered something about exposure times, and he got back into his van and drove off.

*Strangely, I just discovered that my Nightmare Before Christmas calendar has the phases of the moon shifted… well, out of phase. It lists a new moon for Friday instead of a full moon. Everything else is consistent with this placement. Except reality.

Had a chance to run through all my Santiago Fire photos from the last few days with Katie and my parents, and they picked out a few favorites that I hadn’t already posted.

This first one was Monday morning around 10:30, as I drove into the region covered by the smoke plume.

Entering the smoke plume

Just a few minutes later, I had parked at work, deep within that plume. The sky was a hazy orange-brown, and the sun was bright orange, as you can see looking up at this tree.

Orange Sun & Tree

This next picture is yet another view of Monday’s sunset, seen from the 405 near Sand Canyon. This shows more variation in color, with a distinct cone of bright yellow surrounded by red, bounded by gray on the sides and fading to blue above.

Vulcan Sunset

Finally, here’s a view from the Quail Hill area on Tuesday just before sunset. This was taken from Knollcrest Park, roughly the same view as last month’s lenticular cloud photos. This is looking across the Saddleback Valley toward the Santa Ana Mountains. The smoke has cleared enough to see silhouettes, though the light has faded too much to see any more detail. The large plume is rising from Mt. Saddleback, the highest peak(s) in the range. The sun is very close to setting: the houses nearest the ridge are already in shadow, with the next row still in light.

Looking across the valley

Now that the wind and smoke have shifted, watching the progress of the fire has become a nervous office pastime. It’s far enough not to threaten us here, but from the windows along one side of the building, we can see the blackened hills through the haze. And we’ve got people who live in the areas being threatened. Every so often, a group will collect either looking out a conference room window, or checking current fire status online.

Charred Hills

Sunlight is almost normal, if a tad yellowish. I went over to the Spectrum for lunch (yesterday I just ate in the cafe downstairs), and everything looked like business as usual…with one key difference. People weren’t sitting outside if they could help it. Normally, on a day this hot, the tables outside the food court would be full, and small children would be running through the fountain. Today those tables were empty.

Wisps of smoke in the sky

I went up to the top floor of the parking structure to see what I could see, and to be honest, it wasn’t much. Even though the air was (relatively) clear where I was, it was still hazy off in the direction of the hills.

The wind mostly swept the pavement and sidewalks free of ash, but it’s collected on anything rougher—like a lawn. Whenever I cross a strip of grass, little puffs of dust rise around my feet. I had to clean my shoes when we got home.

Around 4:30 or so, the smoke lifted enough that the mountains were visible. After a few minutes, a thin column of smoke rose from behind the hills, with occasional bright flashes visible as flames flared up past the ridge.

Saddleback Smoke

It was getting dark by the time I picked Katie up from her office. On the way home, we could see the top of the ridge of hills silhouetted by a faint orange glow to the southeast.

The wind shifted during the day, and by mid-afternoon the sky near where I work was considerably clearer—even though the fire seemed to be getting closer.

Mt. Saddleback viewed from Tustin foothillsLenticular Line (large)Some geography: The Santa Ana Mountains run parallel to the coast, and form the northeast border between Orange County and Riverside County. Here are a couple of photos from older blog posts showing the hills and the mountains in the background (though from very different angles).

The fire “broke out”* in the foothills on the western side of the mountains. One side went straight over the line of hills and down toward the flatlands, threatening homes in northeastern Irvine last night. That was stopped, but it continued along the canyons to the end of this set of hills, and last I heard had reached the edges of neighboring Lake Forest.

I think the front may have gotten within 4–5 miles of where I work, though we couldn’t see anything but smoke in that direction until late in the afternoon. Every so often I’d wander over to a conference room that normally has a clear view. Off to the northeast, everything faded to brownish gray. It faded to the southwest as well, but at least I could see silhouettes of the hills in the opposite direction.

I did, however, watch ashes floating by horizontally, 4 stories up.

Toward mid-afternoon, the wind (and fire) shifted, moving the worst of the smoke plume away, and outlines became visible. I took this one around 5:30, and you can just see the (likely) charred and smoking hills. (Notice also the orange balloon off toward the left.)

Smoking Hills

With all the smoke in the air, the sunset colors were intense. As the sun sank, it was a brilliant orange.

Orange sunset

Magenta sunAs it neared the horizon, dipping deeper into the layer of smoke, it turned almost purple, and was dim enough to look at directly. (Not that I stared—I’ve seen Pi after all!)

We got a break from the wind for several hours, which just ended minutes ago.

*Reports are that it was arson. What the hell is wrong with people who do this sort of thing? It’s not enough to set a bonfire, or even just burn down one structure—you have to burn down 15,000 acres of wilderness and possibly people’s homes?
