Prescribed fire held in check partially by snow

When I heard this morning that the Black Hills National Forest was going to conduct a 94-acre prescribed fire today I looked out my window at the snow in my yard. Curious about how they were going to accomplish this I departed on a expedition to answer this question. It being close to lunch time I stopped at the Dew Drop In for a burger and their wonderful homemade fries, and then again at the TurtleTown chocolate shop for, obviously, a bag of chocolate turtles.

Passing near the Crazy Horse mega-sculpture I saw two bald eagles on the ground in a pasture. I pulled over onto a nearby side road hoping to get a photo, but they were pretty skittish and rudely flew away. But I still grabbed a few not very impressive photos.

By the time I made it to the Whaley prescribed fire near Hill City, South Dakota, I was no longer hungry and was ready to see how the the U.S. Forest Service fire folks were going to pull this off.

It turned out that there was almost no snow on the south facing slopes and they were about 75 percent done with ignition when I pulled up. But there was still snow in some of the flat lands and shaded areas, enough to make it pretty easy to find snow fields, in addition to roads, to serve as control lines.

At the Elk Mountain weather station the temperature was in the 40s, the relative humidity in the low 30s, and the sky was partly cloudy. As it turned out, a good day for being out in the woods with a drip torch.

Another look at the fatal Decker Fire of 1959

Decker Fire report map diagram

The Decker Fire of 1959, where six firefighters were killed near the U.S. Forest Service El Cariso fire station west of Lake Elsinore, California, is unique among fatal fires for several reasons: three members of the El Cariso Hotshots died, they were only a couple of miles from their home base, a U.S. Forest Service District Ranger was killed, and one of the primary factors that caused the extreme fire behavior was a locally well-known and predictable diurnal wind shift caused by the dry lake bed of Lake Elsinore that turned the flames against the firefighters, trapping and overrunning them on the Ortega Highway. In addition, this tragedy was followed seven years later by another, when the El Cariso Hotshots were overrun by flames on the Loop Fire on the Angeles National Forest in 1966, killing 12 more.

The official report did a pretty good job of explaining the important facts of August 8, 1959. But more than half a century later, a former firefighter who served on the El Cariso Hotshots from 1963 through 1966 conducted extensive research on what happened that day in 1959 and assembled many details that were not included in the U.S. Forest Service report. Julian Lee, Professor of Biology, Emeritus at The University of Miami (now living in New Mexico), made available to us his 27-page description of the Decker Fire. It is very well written and comprehensive, laying out the details of what occurred during and after the fire, as well as providing some analysis.

Mr. Lee’s sources included interviews and correspondence with individuals who were on the fire, CAL FIRE (CDF) documents, newspaper accounts, many USFS documents, training records, documents from ambulance companies, and verbatim transcripts of testimony given by surviving USFS personnel recorded a few days after the incident.

We thank Mr. Lee for his efforts to produce this valuable report, and for his permission to link to it and to post the excerpt below.

There were three burnovers on the fire, but since there were no radios most of the firefighters did not know about them right away unless they were directly involved.

Here is an account of the first, from Mr. Lee’s account:

****

“GUTHRIE BURN-OVER

“… the east flank near the head of the fire blew up, making a run up the east side of Decker Canyon and crossing the Ortega Highway like it wasn’t there.”

While Ferguson was moving his crew out of harm’s way, Will Donaldson, a CDF Tank Truck Driver assigned to San Jacinto Station 26 miles to the northeast, was en route to the fire and listening to radio traffic. An early indication that something exceptional was unfolding on the steep slopes above Elsinore came when he heard a report of “… fire storms, and that something was happening on that fire.”

One of the things happening involved John D. Guthrie, a 25 year old CDF Tanker Foreman and his five man crew. They were one of two units dispatched to the Decker Fire from Old Temecula Station, about 18 miles southeast of the fire. Arriving at around 6:40 p.m., they headed up the Ortega Highway toward the fire, with Guthrie behind the wheel of an International tanker with a 500 gallon capacity. They pulled off at a turn-out at the hair-pin turn (Fig. 2).

Guthrie got out and started down the steep bank to get a better look at the fire burning below. Almost immediately he came scrambling back to the truck, yelling for the men on the back of the truck to get into the cab and to move the truck farther up the road to the protection of the high bank at a nearby road cut. There wasn’t room for Guthrie in the cab; he remained outside, intending to use the tanker’s hose to wet himself down for protection. But suddenly, before they could move the truck, the fire burst upon them.

As the wall of flames engulfed the truck and its occupants, it burned through Guthrie’s hose line, rendering it useless and forcing him to dive under his truck for protection. As CDF tanker foreman Ferguson watched “… the east flank near the head of the fire blew up, making a run up the east side of Decker Canyon and crossing the Ortega Highway (near the hair-pin turn) like it wasn’t there.” He didn’t realize that Guthrie and his crew had been engulfed by the flames as the fire roared across the highway. This, the first of three burn-over events suffered by personnel fighting the Decker Fire, occurred at about 6:40 p.m.

Two of Guthrie’s crewmen, Art Shannon age 28, and Larry Mollers age 19, received serious burns to their arms and hands. Three others, Eugene Golden, Montie Campbell, and Jim Miller received lesser injuries, but Guthrie was burned over 85 percent of his body. He and his injured men were loaded into a CDF pick-up truck and driven to Lakeland Village at the base of the mountain.

There Guthrie was transferred to a 1953 Pontiac ambulance belonging to the Sunnymead Volunteer Fire Department. The ambulance driver headed for Hemet Hospital, but within a few miles the engine threw a piston rod. Coasting to a stop, the driver rushed into a nearby bar, explained their situation and asked to use the telephone. Upon hearing of their plight, a patron pushed the keys to his car across the bar and said, “Take my station wagon and put him in.” Guthrie was treated at Hemet Hospital, stabilized, and then transferred to a hospital in Redlands. He was the first firefighter to be critically burned on the Decker Fire.”

Collecting, processing, and distributing weather and fire behavior data on a smart phone

A modern smartphone has many times the processing power of the computers on the Apollo spacecraft that took astronauts to the moon. Increasingly, wildland firefighters in the field are taking advantage of the smart brilliant devices in their pockets.

An article published in Fire Management Today (in the third quarter of 2015) covers two smart phone applications, or apps. After the user inputs the current weather and environmental conditions they can calculate various parameters and share them via mail or use various archiving options. One of the apps even uploads data to a remote computer server where advanced simulations can be performed which then return forecasts for the next 3 to 12 hours.

Below, FDFM and PIG, are Fine Dead Fuel Moisture and Probability of Ignition. The app can harvest information from the smart phone and insert it into the fields, including time, date, latitude, longitude, and elevation.

Fire Weather Calculator

From Fire Management Today:

This application allows the user to input traditional observations (e.g., dry bulb, wet bulb, etc.) and have the application calculate critical information, such as relative humidity and probability of ignition, which both saves time and ensures consistency between weather observers. More importantly, however, is the ability to archive and share these digital observations with other users and managers in real time. This application allows for more streamlined management of weather information, a critical aspect of any fire event. The ability to share observations, particularly if many users are archiving their observations, will lead to a very useful archive of crowd-sourced data that will be used to create value-added products, such as the calculations of 3-dimensional weather fields that could be shared with personnel to increase their situational awareness.

Fire Weather Calculator is for Android devices and iPhones.

Topofire Weather app

The Topofire Weather app takes the weather calculations to the next level, however it is no longer available. In searching for it we contacted one of the authors of the article, Matt Jolly, a research ecologist at the Missoula Fire Sciences Laboratory, who told us that it has been removed because they “are working on better options for displaying geographic information across all devices, rather than just a few platforms. We are almost ready to release it but development is going slowly right now.”

Topofire Weather looks like it was rather intriguing, as you can see from the description in Fire Management Today:

Similar to the Fire Weather Calculator app described above, this application allows users to enter a suite of fire weather observations that are normally collected on incidents. These observations, as well as the time and location, are sent directly to the TOPOFIRE server, where they are permanently archived and can be made available to users and fire weather forecasters. Weather information entered into the phone can then be used to parameterize the WindNinja simulation model, using either current observations or gridded data from the Real-Time Mesocale Analysis dataset (RTMA).

Users can also request forecasts for the next 3 to 12 hours, using data from the National Digital Forecast Database. Model simulations are then run on the TOPOFIRE server, and outputs are returned to the user’s phone in the form of a keyhole markup language (.KML) file that can be opened on the phone on GoogleEarth.

The Topofire Weather app apparently required access to government computer servers, which may prevent the ordinary user from being able to take advantage of its entire functionality.

We will look forward to the next generation of the app.

National survey – the use of prescribed fire

The National Association of State Foresters and the Coalition of Prescribed Fire Councils recently completed their second national survey of all 50 states, asking questions about how prescribed fire is used, managed, and reported. They found that after sorting the responses into three regions, Northeast, Southeast, and West, 69 percent of all acres burned were in the Southeast in 2014.

The top impediments to accomplishing their prescribed fire objectives were, in decreasing order, weather, capacity, and air quality/smoke management.

Below is an excerpt from the report, and below that some graphics. (click on the images to see larger versions)

One significant finding was an increase in the number of states that offer education and training to certify prescribed fire managers. The number of states increased to 24, a 41% increase over the 2012 report. This is an impressive statistic, and one that will hopefully build capacity of trained fire managers. During the same period, the number of prescribed fire councils grew by 24%, bringing the total to 31 councils in 27 states.

Two killed in Waroona Bushfire in Western Australia

The BBC reports that two people have been found dead in a very large bushfire south of Perth in Southwestern Australia. Police say the bodies of two men in their 70s were discovered in the debris of burnt-out houses in the town of Yarloop. Most of the structures in the town were destroyed when the Waroona Bushfire, pushed by strong winds, raged through the community.

The blaze continues to spread and threaten populated areas, but less intensely now, with less extreme weather conditions. An emergency warning was issued at 10:51 a.m. local time on January 9 for the following locations: Hamel, Cookernup, Yarloop, Harvey, east of Waroona and the surrounding areas. It doesn’t include the Waroona townsite.

The Department of Fire and Emergency Services reports that the fire has consumed 70,876 hectares (175,000 acres) and 143 homes and outbuildings. It is being fought by 250 firefighters, 50 appliances including 38 heavy machines, air tankers, and helicopters. The fire perimeter is more than 140 miles.
