The Tucson SE 7.5' quadrangle is located southeast of the city of Tucson, Arizona, between Wilmot and Houghton Roads and bisected by Interstate 10. Regionally, the map area is southwest of the Pantano Wash. Portions of this map area have been developed since the most recent aerial photography; therefore these areas were mapped from the air photos and ground checked where possible. These areas are outlined on the map by thick, dotted red lines. Field work was carried out between November, 2003 and June, 2004. The surficial deposits were mapped using aerial photos from digital orthoquad photos, color aerial photos, and field mapping. This report also includes descriptions of various geologic hazards and surficial geology within the mapped area. The surficial geologic map itself provides a substantial amount of information about the aerial distribution of various geologic hazards in this area, because some hazards correlate with surfaces of different ages. Soil characteristics that may impact human structures, including clay content, carbonate accumulation, and potential for compaction, vary with each surface. Flooding in the past can be relatively predicted using the age and elevation of the surface with respects to regional drainage. This map should be used as a guide for more in-depth investigation in the potential for geologic hazards within the mapped area.
