[US FIRETOWER TYPOLOGIES]
Fire lookout towers proliferated in the United States in the mid-1900s for wildfire prevention in remote, forested areas, particularly across the national forests. Their elevated positions provided a panoramic view to detect smoke and flames before fires could spread.
Over time, the majority of these lookout towers have became decommissioned as fire surveillance shifted to aerial surveillance through satellites and remote cameras. Only a few towers remain in use today, although others may also remain preserved as historic sites.
