Abstract

The human-caused Schultz Fire near Flagstaff, Arizona burned 6,100 ha (15,075 acres) on the Coconino National Forest between June 20th and 30th, 2010. Ignited by an abandoned campfire, high winds drove the fire over approximately 60% of the total area burned during the first 12 hours (U.S. Forest Service, 2010). The majority of the area burned at moderate (27%) or high (40%) severity across slopes of 30% to over 100%, through forests of ponderosa pine and mixed conifer. Nine of eleven 6th code watersheds were almost completely burned, with areas of high burn severity covering more than 50% in three watersheds and more than 70% in two others. Subsequent rains from the 4th wettest monsoon on record produced numerous floods and debris flows across the burned area and caused extensive damage to downstream communities.
