The Waldo Canyon Fire has been declared the worst in Colorado state history, but it is small compared to the fires in the 19th century that scorched millions of acres.
The Waldo Canyon Fire has been declared the worst in Colorado state history. With its flames still raging out of control, it has destroyed 346 homes in Colorado Springs, killed at least one person and burned an estimated 18,500 acres of land thus far. Meanwhile, the High Park Fire is charring pine forests in nearby Fort Collins.
But how do the Colorado wildfires compare to history's biggest blazes?
During the 19th and early 20th centuries, huge uncontrolled wildfires periodically arose that destroyed millions of U.S. acres, according to the National Park Service (NPS). In 1825, the Great Miramichi Fire burned 3 million acres in Maine and New Brunswick and killed at least 160 people. Two decades later, Oregon's Great Fire of 1845 blazed for weeks and downed 1.5 million acres of old-growth timber.
