Fire lookout tower

A fire lookout tower, fire tower, or lookout tower is a tower that provides housing and protection for a person known as a "fire lookout", whose duty it is to search for wildfires in the wilderness. It is a small building, usually on the summit of a mountain or other high vantage point to maximize viewing distance and range, known as view shed. From this vantage point the fire lookout can see smoke that may develop, determine the location by using a device known as an Osborne Fire Finder, and call for wildfire suppression crews. Lookouts also report weather changes and plot the location of lightning strikes during storms. The location of the strike is monitored for a period of days afterwards, in case of ignition.

A typical fire lookout tower consists of a small room, known as a cab, atop a large steel or wooden tower. Historically, the tops of tall trees have also been used to mount permanent platforms. Sometimes natural rock may be used to create a lower platform. In cases where the terrain makes a tower unnecessary, the structure is known as a ground cab. Ground cabs are called towers, even if they do not sit on a tower.

Towers gained popularity in the early 1900s, and fires were reported using telephones, carrier pigeons and heliographs.

Although many fire lookout towers have fallen into disrepair from neglect, abandonment and declining budgets, some fire service personnel have made efforts to preserve older fire towers, arguing that a person watching the forest for wildfire can be an effective and cheap fire control measure.

The history of fire lookout towers predates the United States Forest Service, founded in 1905. Many townships, private lumber companies, and State Forestry organizations operated fire lookout towers on their own accord.

The Great Fire of 1910, also known as the Big Blowup, burned 3,000,000 acres (12,000 km²) through the states of Washington, Idaho, and Montana. The smoke from this fire drifted across the entire country to Washington D.C. — both physically and politically — and it challenged the five-year-old Forest Service to address new policies regarding fire suppression, and the fire did much to create the modern system of fire rules, organizations, and policies. One of the rules as a result of the 1910 fire stated "all fires must be extinguished by 10 a.m. the following morning."

To prevent and suppress fires, the U.S. Forest Service made another rule that townships, corporations and States would bear the cost of contracting fire suppression services, because at the time there was not the large Forest Service Fire Department that exists today.

As a result of the above rules, early fire detection and suppression became a priority. Towers began to be built across the country. While earlier lookouts used tall trees and high peaks with tents for shelters, by 1911 permanent cabins and cupolas were being constructed on mountaintops.
