Deconstructing geologic maps exhibit at Pima Co library

What does it take to make a geologic map, from start to finish?

AZGS set up an 8-panel display in the Pima County (Tucson) Public Library, entitled "Deconstructing Geologic Mapping of the San Pedro Valley with Joe Cook." The display walks the viewer through the steps of making a geologic map from "Getting Started" -- pulling together the aerial photos, previous geologic mapping and topographic base --, through field work and field hazards -- floods, rattlesnakes, dogs and No Trespassing signs -- to digitizing the field sheets in a GIS to the final published geologic map. The story is drawn from the real experiences of AZGS geologist Joe Cook.
