We often hear, “It’s not IF an area will burn, but WHEN”.
Capital Public Radio has developed an interactive map showing the footprints of wildfires that have occurred in California since 1878. You can see all of the fires at once, or individual years, and the map is zoomable. (The map may not display well in all browsers. It seems to work best using Firefox.)
I may or may not have spent too much time looking at these maps.
Above: Map of the Detwiler Fire. The yellow line was the perimeter at 1 a.m. PDT Tuesday July 18, 2017. The red dots represent heat detected by a satellite at 1:48 p.m. PDT July 18. The satellite detections can’t be relied upon to be 100 percent accurate. The very intense smoke plume over the fire on Tuesday may have contained enough heat to trip the sensors on the satellite, giving the impression that the fire was larger than it actually was.

(All articles on Wildfire Today about the Detwiler Fire are tagged “Detwiler Fire” and can be found here, with the most recent at the top.)
The Detwiler Fire continued to be very active Tuesday afternoon. CAL FIRE, the agency responsible for suppressing the blaze, estimated at 7 p.m. that the size had increased to about 25,000 acres, up from 19,601 at 1 a.m. on Tuesday. They reported that 8 structures have been destroyed, but did not specify if they were residences or outbuildings.
The CAL FIRE web site sometimes has information about evacuations.
The fire spread to the south Tuesday, pushed by a wind out of the north. Winds from the north are expected to continue through the night and into Wednesday morning at 6 to 9 mph, shifting to come out of the west in the afternoon. Wednesday’s temperature in the fire area will top out at 98 degrees, with the relative humidity hitting 14 percent in the afternoon.
The Detwiler Fire has been very, very active Tuesday afternoon, spreading very quickly and putting up a huge smoke plume. For a while at mid-afternoon at least one air tanker working the fire, a DC-10, was diverted to a new fire 6 miles southeast of Redding. During that time the KCRA live video did not show any air tankers on the Detwiler Fire, but after a while there were two DC-10s, an MD-87, a C-130, and at least one S2T working the fire again.
The camera operator for KCRA has no trouble finding action to film — air tankers dropping, massive flames, or a towering convection column.
The Detwiler Fire has grown explosively since it started less than 48 hours ago during the afternoon of July 16. At 1 a.m. PDT on July 18 it was mapped at 19,610 acres, an increase of 16,192 acres over the previous 24 hours.
The fire is 6 miles northwest of Mariposa.
The maps of the Detwiler Fire below were current at 1 a.m. PDT July 18, 2017.
It is already causing evacuations in areas of Mariposa County, according to the Sheriff’s office. At 12:30 p.m. PDT Tuesday CAL FIRE revised their information about the fire to indicate that the city of Mariposa is being evacuated, but by 1:18 p.m. PDT the Sheriff’s Office had not stated it like that on their web site. However, the Sheriff’s site lists about 19 locations that ARE evacuated, without providing a map, so it can be a little difficult to get the entire picture.
Highway 49 is closed. Power lines that supply electricity to Yosemite National Park, which is 19 air miles to the east, could be impacted.
The time-lapse video below was filmed by Toney Gorham between 7:30 and 8:30 p.m. on Sunday July 16.

This map was provided by Oklahoma Forestry Services, along with the information that the fire had burned an estimated 397,420 acres and was 0% contained Thursday morning.
(UPDATED at 6:12 p.m. CDT March 24, 2016)
The video below is a recording of the briefing by public officials of Barber County Kansas the morning of March 24, 2016 about the very large fire insouthern Kansas and northern Oklahoma. It was originally broadcast on Periscope by Amy Bickel, but since recordings there are automatically deleted after 24 hours, we preserved it here. It was recorded off a computer monitor, so we apologize for the low quality.
In the briefing referenced above, the County Attorney said “397,420 acres have burned over the last couple of days”. He did not indicate if that was the size of the very large fire in our maps, or if the acreage includes multiple fires. He also said two homes were destroyed.
The map below shows heat detected by a satellite at 2:25 p.m. on March 24. The light vegetation in the area may sometimes ignite, burn up completely, and then cool before the next satellite overpass, which can be about 12 hours apart. In this case the mapped data may under-report the true extent of the fire.
Here is an excerpt from an article at WIBW, dated March 24 at 2:10 p.m.
Strong winds have thwarted efforts to contain a wildfire that has burned 620 square miles of rural land in Oklahoma and Kansas, and it’s now approaching populated areas.
Oklahoma Forestry Services spokesman Mark Goeller said Thursday that strong winds shifted the direction of the fire late Wednesday and overwhelmed existing containment lines.
Officials are now monitoring a part of the blaze 5 miles away from Alva, Oklahoma, where about 5,000 people live. No mandatory evacuations have been issued in Oklahoma, though Goeller says officials are forming contingency evacuation plans as crews work to slow the fire’s spread.
Goeller says wind conditions and humidity are expected to improve throughout the day, making progress on containment more likely…
The Solimar Fire northwest of Ventura, California as of 5:40 p.m. PST had not grown appreciably since early Saturday morning, and was mapped at 1,236 acres. Approximately 403 firefighters were on scene at that time as well as one helicopter.
The 101 Freeway, which had been closed in both directions is now open and evacuations have been lifted.
The weather has changed from strong gusty winds Friday night to a Saturday night forecast of 7 mph north winds, 37 degrees, with 30 percent humidity.
(Originally published at 11:05 a.m. PST, December 26, 2015)
A vegetation fire has burned about 1,200 acres in southern California northwest of the city of Ventura. The Solimar Fire started at about 11 p.m. PST Christmas day and spread quickly, pushed by 50 mph winds.
The fire, burning on both sides of the 101 freeway near the Pacific coast, caused havoc among motorists when some of them made U-turns on the blocked divided highway, fleeing from the fire through opposing traffic, much to the surprise of the unaware oncoming drivers.
The 101 is closed and mandatory evacuations are still in place as this is written at 10:56 a.m. on Saturday.
The good news is that, again, the Pacific Ocean proved its value as a very adequate fuel break.
The video below was a 2 a.m. briefing by the Ventura County Fire Department.
Strong winds on the day it started spread it across 2,500 acres by the next morning on lands managed by the Idaho Department of Lands, Southwest Forest Protective District, and the Boise National Forest. It is burning on both sides of Grimes Creek Road. Three cabins and one outbuilding have been destroyed.
The fire was very active on the north side on Tuesday.
Evacuations have been ordered for residents in Macks Creek, Wolf Creek, and Pine Creek.
Smoke from the fire has caused air quality alerts in the Treasure Valley area.
