dc.descriptionThe central Verde River is one ofthe primary perennial, free-flowing streams in Arizona. Portions ofthe river have been significantly impacted by human activities, and its future flow may be threatened by groundwater depletion. The Arizona Geological Survey received a grant from the U.S. Environmental Protection Agency to evaluate and map the geologic units along the Verde River between Sullivan Lake in Big Chino Valley and Horseshoe Reservoir as part of an Advanced Identification (ADID) project to identify sites that may be suitable or are generally unsuitable for disposal of dredged or fill material. Variations in the physical characteristics of geologic units found along the Verde River have important implications for assessment of the riparian environment because they are the substrate for riparian biotic communities and they are the primary aquifers for riparian vegetation along the river. This report summarizes the geologic and geomorphic setting of riparian areas along the central Verde River. Geologic units along the Verde River were mapped through interpretation of aerial photographs, field checking and description of units, analyses of topographic maps, and compilation of mapping by previous workers. Mapping focused on alluvial deposits associated with the Verde River and its tributaries because these deposits had not been mapped previously in any detail. Alluvial deposits were differentiated into five age categories ranging from modern to more than 1 million years old; deposits of the Verde River and its perennial tributaries were discriminated from deposits of smaller, ephemeral tributaries. Basin-fill sediments and bedrock were divided into 5 general categories based on their age and physical properties. (25 pages)
