Three Idaho firefighters injured when gas can falls off truck and ignites

Three firefighters with the Downey Fire Department in southeast Idaho (map) were injured when a gas can fell off their truck while fighting a vegetation fire. They were backing at the time and one of the tires on the five-ton, 6×6 truck ran over the can. The spilled gas ignited from an ember in the burned over area where they were at the time. The intense fire that developed burned all three firefighters, one of them over 40 percent of his body.

All three were transported to a hospital and two were transferred to the University of Utah Burn Center in Salt Lake City where a spokesperson said one was in critical condition and another was in serious condition. The third was treated and released. One of them also suffered a broken leg.

The truck was destroyed and the fire was knocked down after it spread to six acres.

It has been many days since we were able to find a satellite photo free of clouds enough to see smoke from the wildfires in Western Montana and Northern Idaho, but today there were few clouds in the area. This photo from Tuesday afternoon shows less heat (the red dots) than what we were seeing one to two weeks ago.

Dozens of active wildfires in the Northwest U.S.

Dozens of wildfires are active in the Northwest one-quarter of the United States. Many of them have been burning for several weeks under a limited suppression strategy. The states of Washington and Oregon have a total of 32 large uncontained fires that have spread over 810,171 acres.

Wildland firefighters are much busier this year than in a typical year. To date, fires have burned 46 percent more acres than the 10-year average — 5,820,802 acres vs. the 3,962,906 average. In some years fire activity in Alaska, where many very large fires are not suppressed, can inflate these numbers, but so far that state can only account for 626,786 acres, not a huge number for Alaska.

400 hand crews, usually comprised of 20 people each, are deployed nationwide, along with 949 fire engines, and 120 helicopters for a total of 16,673 personnel.

Map showing heat detected on the Powerline Fire southwest of Pocatello, Idaho by a satellite August 5 and 6, 2016. The red dots are the most current, at 4:04 a.m. MDT August 6. Some areas with light vegetation, such as grass, may have burned and cooled before the satellite overflight and were not detected.

Here are brief descriptions of some of the larger or more prominent fires:

  • Powerline (see the map and photo above): Since it was reported Friday night this fire has spread very rapidly. Saturday it was very active on the northeast and southeast sides. Using satellite data the Incident Management Team estimated early Sunday morning that it had burned over 40,000 acres, but that is a very rough guess. More accurate mapping by fixed wing aircraft will provide better numbers. The satellite information indicated that by 4:04 a.m. Sunday it had spread to within 6 miles of Pocatello, Idaho. It is moving into steeper terrain with heavier fuels, offering more resistance to control and is the #2 priority in the Great Basin Geographic Area according to the national situation report.
  • Mammoth Cave, southwest of Carey, Idaho. Since it started August 4 it has burned three structures and 30,000 acres. It is the number 1 priority in the Great Basin Geographic Area.
  • The Shoestring Fire between Shoshone and Gooding, Idaho has blackened about 12,000 acres since it started August 5. It is the #3 priority in the Great Basin Geographic Area.
  • The Rice Ridge Fire northeast of Seeley Lake, MT is the #1 priority in the Northern Rockies Geographic Area and is threatening over 1,000 structures. It added almost 700 acres on Saturday to bring the total to 7,740.
  • The Sunrise Fire, 12,900 acres, the #2 priority in the Northern Rockies Geographic Area, grew by 600 acres Saturday. It has been burning since July 16, growing every day, adding several hundred acres daily on the east or northeast sides. It is now mapped at 12,900 acres.
  • The Hanover Fire, in a very remote area 15 miles northwest of Riggins, Idaho, was extremely active on Saturday. The Incident Management Team reports that it has burned 4,479 acres.
  • Parker 2, 10 miles east of Alturas, California. It was very active Saturday, adding 5,300 acres, growing to 7,100 acres.
  • Minerva 5, just south of Quincy, California. It has burned 4,088 acres and the voluntary evacuation of the town has been lifted. Firefighters completed a firing operation Saturday night.

Fires in Western Montana still very active

The fires are consuming thousands of acres each day and producing large quantities of smoke.

The residents of Western Montana have been dealing with wildfire smoke for several weeks and there is no relief in sight.

Our map above identifies eight of the largest blazes in the area. Here are a few facts about some of them, with them ranked in priority order according to fire management officials.

  • Sunrise: Six miles south of Riverbend, 9,900 acres, 548 personnel assigned.
  • Sapphire Complex: Three fires, 15 miles southeast of Clinton, MT, 12,756 acres, 864 personnel assigned.
