 In remote areas and wilderness parks, fires may be left to burn as part of the natural ecological cycle.Wildfire suppression in the United States has had a long and varied history.For most of the 20th century, any form of wildland fire, whether it was naturally caused or otherwise, was quickly suppressed for fear of uncontrollable and destructive conflagrations such as the Peshtigo Fire in 1871 and the Great Fire of 1910.
