In July of 2019 the Museum Fire of Northern Arizona burned 1,961 acres of Ponderosa pine and mixed conifer forest. This was caused by a forest-thinning project which was originally undertaken to help prevent devastating wildfires. The fire was started from a piece of heavy equipment striking a rock and sparking the blaze. Nearby neighborhoods were forced to evacuate. According to the National Forest Service, the fire cost $9 million before it was brought under control. This section of burned trees was photographed from the Sunset Trail in the Coconino National Forest near Flagstaff, Arizona, USA.
