The origin of this fire is officially under investigation. The park service has been letting the lightning-caused Meadow Fire burn for awhile, and it’s likely that embers from the Meadow Fire were picked up and blown into an area with heavy fuels, then were fanned by the wind. But it’s also possible that this is a new fire with an unknown cause.
In either case, the winds caused this fire to blow up suddenly Sunday at about 12:30 p.m., closing all the trails in and around Little Yosemite Valley, and forcing the park service to evacuate 50 hikers from the top of Half Dome by helicopter! A big news story, as you can imagine. As of yesterday, the fire was estimated at 4,400 acres. They’re using helicopters, air tankers, and ground crews to contain it. All the park roads and facilities are open, and fortunately no one has been injured by the fire.
There were quite a few photographers at Washburn Point Sunday night, and no wonder – the fire was a spectacular sight. Moonlit clouds kept streaming in from the south, and several times we saw lightning in the distance. Two separate rain showers just missed us, but passed directly over the fire. The first shower seemed to noticeably dim the flames. After the second, heavier shower, a large bank of fog rose up, obscuring the fire and Half Dome. The fog may actually have been steam, created by water hitting the fire. These brief showers didn’t put the fire out, but they probably slowed it down.
The clouds added a lot to the photographs. I made the image at the top of this post during a brief time when the fire was particularly active, and low clouds were passing overhead. The glow from the fire lit the underside of the clouds, making it look like the whole world was on fire. The panorama below was made after the second rain shower passed through, as moonlight broke through the clouds and illuminated Half Dome. You can see some rain falling behind Half Dome in this image:
If it does turn out that this was a spot fire from the Meadow Fire, the park service will undoubtedly face criticism for letting this burn. But they have a tough job. Fire is a natural and inevitable event in western North-American forests. If the park service doesn’t let some fires burn, or deliberately set fires to thin brush and undergrowth, then the fuels will keep accumulating. When that fuel-laden forest burns, the fire will be huge and catastrophic, killing not just the brush and small trees, but the big trees as well – not to mention posing a huge threat to any people and structures in the fire’s path.
That’s what happened with the enormous Rim Fire last year. It started in National Forest lands, where fuels had been accumulating for probably 100 years. After two years of drought, with all that undergrowth to feed on, the fire just exploded. In one day it doubled in size from 25,000 acres to 50,000 acres. The next day it doubled again – to over 100,000 acres.
The Rim Fire then moved rapidly east, reached the boundary of Yosemite National Park… and slowed down. The park’s more open forests – created by allowing low-intensity fires to burn – had less fuel for the Rim Fire to feed on. The fire eventually burned 257,000 acres (most of it outside the park), making it the largest fire in the recorded history of the Sierra Nevada. In some places, the fire burned so hot that it consumed everything. In other places, it left a patchwork of burned and relatively unscathed areas, with most of the large trees surviving. All of the hottest areas, the large swaths where every tree died, were outside the park.
Sooner or later, every acre of forest in the Sierra Nevada (and most other western forests) will burn. Our only choice is whether to have frequent, low-intensity fires, or infrequent but catastrophic fires. I’d prefer frequent, low intensity fires. But I recognize that this kind of fire management does carry risks. Fire is unpredictable, and sometimes these managed fires will get out of control and become big fires. It’s tragic when homes are destroyed or lives lost when a managed fire gets out of control. But in the long run the risks to homes, lives, and mature trees are probably greater if we don’t allow some fires to burn.
After staying up most of Sunday night photographing the Meadow Fire, I was trying to sleep late Monday morning (in Mariposa, just outside Yosemite) when I was rudely awakened by loud claps of thunder. One very close lightning strike knocked out a surge protector and caused our internet connection to go out. Several more showers passed through – very unusual for early September in Mariposa. On the webcam, I saw more rain falling on the fire Monday, and the smoke was greatly diminished compared to Sunday. It seems likely that the fire will be contained soon.
But the memory of watching the fire Sunday night lingers. Standing at one of the park’s most spectacular viewpoints, watching the glow from the fire illuminate Half Dome, with moonlit clouds passing overhead and flashes of lightning in the distance, is something I won’t soon forget.
