The June 2005 Cave Creek Complex Fire is one of the largest historic wildfires to affect Arizona's Sonoran Desert. Post-fire gullying was measured using pre-fire and post-fire aerial photographs from the Maricopa County (after the 2005 and 2006
Arizona monsoon) and ground-based surveys. Results and discussion. A corresponding field-based investigation reveals both deepening and widening of gullying over time.
