The Tillamook Burn was a series of forest fires in the Northern Oregon Coast Range of Oregon in the United States that destroyed a total area of 355,000 acres (1,440 km2) of old growth timber in what is now known as the Tillamook State Forest. The fires spanned the years of 1933–1951. By association, the name Tillamook Burn also refers to the location of these fires. This event is an important part of the local history of Oregon.
There were four wildfires in this series. The first was started in the Gales Creek Canyon on August 14, 1933, when a steel cable dragging a fallen Douglas fir rubbed against the dry bark of a wind-fallen snag. The snag burst into flame, and the wildfire that grew out of this burned 311,000 acres (1,260 km2) before it was extinguished by seasonal rains on September 5. An oppressive, acrid smoke filled the neighboring valleys; ashes, and cinders, and the charred needles of trees fell in the streets of Tillamook; and debris from the fire reached ships 500 miles (800 km) at sea. The loss in processed lumber was estimated to have been $442.4 million in contemporary (1933) dollars—a serious loss not only to the timber industry at the time, but also to a nation struggling with the Great Depression. Salvage operations were immediately begun to harvest usable portions of the burned wilderness. A Civilian Conservation Corps member was the only known human casualty of fighting the fire.
The speed with which a forest fire can spread in heavy fuels under the most hazardous conditions is well illustrated by this fire. From August 14 at 1 p.m. until the early morning of August 24 the fire had burned about 63 square miles (160 km2) and it appeared that it might be brought under control soon. Thus, for over 10 days it had burned at an average rate of about 6 square miles (16 km2) a day. On August 24, the humidity dropped rapidly to 26 percent and hot gale force winds from the east sprang up. During the next 20 hours of August 24 and 25 the fire burned over an additional 420 square miles (1,100 km2), or at a rate of 21 square miles (54 km2) per hour along a 15-mile (24 km) front. The fire was stopped only by the fact that the wind ceased and a thick, wet blanket of fog drifted in from the ocean.
The second fire was started in 1939, allegedly by another logging operation. It burned 190,000 acres (770 km2) before being extinguished, and was contained within the bounds of the earlier fire.
A third fire started on the morning of July 9, 1945, near the Salmonberry River, and was joined two days later by a second blaze on the Wilson River, started by a discarded cigarette. This fire burned 180,000 acres (730 km2) before it was put out. The cause of the blaze on the Salmonberry River was mysterious, and many believed it had been set by an incendiary balloon launched by the Japanese, which had been carried to Oregon by the jet stream.
The third fire was perhaps the best known, after the initial wildfire, because it affected much of the forested mountains along the popular highways between Portland, Oregon and the recreational destinations of the Ocean beaches. This devastation remained visible to any traveller through the area as late as the mid-1970s.
The last fire started in 1951, and burned only 32,700 acres (132 km2). It was also confined within the burned-over area.
Much of the lands of the Tillamook burn had come to be owned by the counties of Tillamook, Yamhill, and Washington through foreclosures on unpaid property taxes; at the time of the forest fires, most of the land was owned by timber companies, which also paid the cost of fighting the fires. A measure was submitted by the Legislative Assembly to the voters to float a bond to finance reforestation, which narrowly passed in 1948.
In a book published that same year, Stewart Holbrook wrote about the Tillamook burn in Northwest Corner: Oregon and Washington:
[Reforestation] can never compensate for that tragedy we call the Tillamook Burn, as somber a sight as to be viewed this side of the Styx. There they stand, millions of ghostly firs, now stark against the sky, which were green as the sea and twice as handsome, until an August day of 1933, when a tiny spark blew into a hurricane of fire that removed all life from 300,000 acres (1,200 km2) of the finest timber even seen. It was timber, too, that had been 400 years in the making. It was wiped out in a few seething hours which Oregon will have reason to remember well past the year 2000. To this day the forest stands powerless against the threat of wildfires.
Reforestation was performed simultaneously with research into the best methods. Young people from northwest Oregon helped with the hand-planting of seedlings. Between 1949 and 1972, they planted about a million seedlings or about 1 percent of the total of 72 million seedlings replanted by all means. In 1973, Oregon Governor Tom McCall dedicated the Tillamook Burn as the Tillamook State Forest.
At the time the reforestation of the Tillamook Burn began, some assumed that the forest land would, when the trees were mature, be harvested for lumber. Current environmental beliefs have questioned this assumption, and both the proportions and specific parts of this land that will be logged or conserved for wildlife are in dispute.
