How did the 1910 fire stop?
Most of what was destroyed fell to hurricane- force winds that turned the fire into a blowtorch. Re-constructing what happened, leads to an almost impossible conclusion: Most of the devastation occurred in a six-hour period.
What was the effect of US fire policy that was in place for most of the 20th century?
For most of the 20th century, U.S. federal fire policy focused on suppressing all fires on national forests. The goal was to protect timber resources and rural communities, but this policy ignored the ecological importance of fire. North American forests have evolved with fire for thousands of years.
What causes the wildfires that burn thousands of acres?
Wildfires do sometimes occur naturally, either ignited by the sun’s heat or a lightning strike. However, most wildfires are caused by human activities, including unattended campfires, discarded cigarettes, arson and more.

What is the problem with fire suppression?
Fire suppression leads to the buildup of dead biomass in fire-prone ecosystems which may produce more severe fires when they do burn.
What event occurred in 1910 and how did it affect the mission of the US Forest Service?
In the summer of 1910, a devastating series of forest fires swept over Idaho, Montana, and Washington, culminating on August 20–21 in what is known as the “Big Blowup.” Coming only five years after the U.S. Forest Service’s establishment, this seminal event made a deep and lasting impact on the agency.

What caused the wildfires of the late 1990s?
The late 1990s were a period of transition in certain climate cycles that tend to shift every few decades. 18 This shift—combined with other ongoing changes in temperature, drought, and snowmelt—may have contributed to warmer, drier conditions that have fueled wildfires in parts of the western United States. 19, 20
Is there a trend in the extent of wildfires?
The data do not show an obvious trend during this time. The extent of area burned by wildfires each year appears to have increased since the 1980s.
