The Cameron Peak wildfire in Colorado started on August 13, 2020. As of October 13, 2020, two months later, the fire was still only 56% contained and 850 firefighters are still at work on the blaze. The fire has burned 134,960 acres, almost 211 square miles (about the size of a small county).
Fortunately, the Cameron Peak fire has not yet caused any deaths and has only caused modest structure damage as it is mostly deep in a mountain forest.
These huge wildfires are something new. All of the twenty largest wildfires in Colorado history have taken place since 2002. Three have taken place this year. The 21st largest dates to 1879, a full 123 years before the latest round of huge Colorado wildfires began. The Cameron Peak fire is the third largest fire in state history behind this year’s Pine Gulch fire (which was 100% contained on September 24, 2020), which burned 139,007 acres, the largest in Colorado history, and the 137,760 acre Hayman fire in 2002.
These fires caused just seven deaths over eighteen years, however, and destroyed 1,169 structures, with the majority of lives lost and structures destroyed arising from a single fire (the Hayman fire in 2002). Three of the fires caused by loss of life and destroyed structures. Three more destroyed structures but caused no loss of life. Fourteen caused no loss of life and destroyed no structures.
This is due mostly due to a combination of drought, a pine beetle infestation, fire suppression that prevented smaller natural wildfires from removing fuel from the forest, and increased human populations that are interacting with the land to start fires, and also diverting water from the forests for agriculture and urban use.
These twenty wildfires (which are not a comprehensive list of all wildfires in the last eighteen years), have burned 1,231,851 acres (about 1,925 square miles which is about 1.8% of the land in the state) in Colorado (one of which burned additional acres in Kansas).
