The Arizona Dept. of Water Resources has released detailed geologic maps of Holocene units along tributaries of the Verde River drainage that were done by AZGS. The maps are located at http://www.azwater.gov/AzDWR/SurfaceWater/Adjudications/
They are situated at the bottom of the page and referred to as Phase II Summary Report.
The mapping was led by AZGS geologist Joe Cook under contract to ADWR for anticipated use in groundwater - surface water adjudication hearings. The geologic maps along the main Verde River were previously released by ADWR and AZGS.
