Wildfire’s size shows vastness of U.S. West

PORTLAND, ORE. » The monstrous wildfire burning in Oregon has grown to a third the size of Rhode Island and spreads miles each day, but evacuations and property losses have been minimal compared with much smaller blazes in densely populated areas of California.

The fire’s jaw-dropping size contrasted with its relatively small impact on people underscores the vastness of the American West and offers a reminder that Oregon, which is larger than Britain, is still a largely rural state, despite being known mostly for its largest city, Portland.

The 476-square-mile Bootleg fire is burning 300 miles southeast of Portland in and around the Fremont-Winema National Forest, a vast expanse of oldgrowth forest, lakes and wildlife refuges.

If the fire were in densely populated parts of California, “it would have destroyed thousands of homes by now,” said James Johnston, a researcher with Oregon State University’s College of Forestry who studies historical wildfires. “But it is burning in one of the more remote areas of the lower 48 states. It’s not the Bay Area out there.”

At least 2,000 homes have been evacuated at some point during the fire and another 5,000 threatened. At least 70 homes and more than 100 outbuildings have gone up in flames. Thick smoke chokes the area where residents and wildlife alike have already been dealing with months of drought and extreme heat. No one has died.

Pushed by strong winds from the southwest, the fire is spreading rapidly to the north and east, advancing toward an area that’s increasingly remote.

Evacuation orders on the fire’s southern edge, closer to more populous areas such as Klamath Falls and Bly, have been lifted or relaxed as crews gain control. Now it’s small, unincorporated communities such as Paisley and Long Creek — both with fewer than 250 people — and scattered homesteads that are in the crosshairs.

“The Bootleg fire is threatening ranch houses that are in pretty far-flung areas,” Johnston said. “There are no suburbs in that area.”

But as big as the Bootleg fire is, it’s not the biggest Oregon has seen. The fire’s current size puts it fourth on the list of the state’s largest blazes in modern times, including rangeland fires, and second on the list of infernos specifically burning in forest.

These megafires usually burn until the late fall or even early winter, when rain finally puts them out.

The largest forest fire in modern history was the Biscuit fire, which torched nearly 780 square miles in 2002 in the Rogue River-Siskiyou National Forest in southern Oregon and northern California. The largest fire of any type was the Long Draw fire in 2012, which incinerated 872 square miles of mostly sagebrush and rangeland in the endless expanses of southeastern Oregon, where almost no one lives.

By the time the Bootleg fire is extinguished months from now, it will likely be as big or bigger than those fires, but research shows that Oregon once experienced megafires much larger than these fairly often, Johnston said.

“I think it’s important for us to take the long view of wildfire. In the context of the last couple hundreds years, the Bootleg fire is not large,” he said. “One of the things my lab group does is reconstruct historical fires, and fires that were burning in that area in the 1600s and 1700s were just as big as the Bootleg Fire or bigger.”

That’s little reassurance for fire crews battling the current blaze, which is 25% contained.

On Monday, flames forced the evacuation of a wildlife research station as firefighters had to retreat from the flames for the ninth consecutive day due to erratic and dangerous fire behavior.

The Bootleg fire was one of many fires burning in a dozen states, most of them in the U.S. West. Sixteen large uncontained fires burned in Oregon and Washington state alone on Monday, affecting a total of 767 square miles, the Northwest Interagency Coordination Center said.

In California, meanwhile, Pacific Gas and Electric, the state’s largest utility, said that blown fuses on one of its utility poles may have sparked the Dixie fire, which has burned through 30,000 acres in Northern California, The New York Times reported.
