As a result of recent large wildfires, Post-Fire Site Survey projects have occurred 10 out of the past 12 years. A total of 682 new archeological sites were discovered and recorded during the surveys. Archeologists have discovered that the Ancestral Puebloans were even more successful farmers than originally believed. Post-fire surveys have led to the recordation of many more check dams and water control features than in previous surveys. These features typically consist of retaining walls placed on slopes in order to direct water to catchment features or to agricultural plots.
After each wildfire, teams of archeologists survey the fire areas and assess, document, and treat previously recorded and newly discovered sites. Treatment methods include reseeding to promote vegetation growth, placement of erosion control features such as log diverters to direct water away from sites, and the installation of silicone driplines in cliff dwellings.
