This report contains four detailed maps depicting the distribution of Quaternary alluvial deposits and their associated geomorphic surfaces in the northern portion of the Verde Valley. Preliminary age estimations based on relative age criteria and soil development characteristics are assigned to each unit. Each map also depicts the distribution of generalized bedrock types in the area. Geologic structures in the bedrock units other than the principal trace of the Verde Fault are not included in these maps. Each map in this report contains a wealth of geological information concerning the effects of Quaternary climatic fluctuations on the evolution of the Verde River, its major tributaries, and adjacent piedmont areas. Evident in these maps is the strong influence of drainage basin and substrate lithology on the evolution of the regional landscape and the persistence of landforms. In addition, the maps contain information relevant to the distribution and character of flood hazards, vegetation assemblages, and potential soil problems. (20 pages; 4 map sheets, map scale 1:24,000)
