The Waldo Canyon fire descends into the Mountain Shadows neighborhood in Colorado Springs, burning 347 homes in a matter of hours and killing two people.

The Waldo Canyon fire was a forest fire that started approximately 4 miles (6.4 km) northwest of Colorado Springs, Colorado on June 23, 2012, and was declared 100 percent contained on July 10, 2012, after no smoke plumes were visible on a small portion of the containment line on Blodgett Peak. The fire was active in the Pike National Forest and adjoining areas, covering a total of 18,247 acres. The fire had caused the evacuation of over 32,000 residents of Colorado Springs, Manitou Springs and Woodland Park, several small mountain communities along the southwestern side of U.S. Highway 24, and partial evacuation of the United States Air Force Academy. There were 346 homes destroyed by the fire. U.S. Highway 24, a major east–west road, was closed in both directions. The Waldo Canyon Fire resulted in insurance claims totaling more than US $453.7 million. It was the most destructive fire in Colorado state history, as measured by the number of homes destroyed, until the Black Forest Fire surpassed it almost a year later when it consumed 486 homes and damaged 28 others.
