Geologic Map of the Fredonia 30’ x 60’ Quadrangle, Mohave and Coconino Counties, Northern Arizona

By George H. Billingsley, Susan S. Priest, and Tracey J. Felger

1:24,000-scale Maps of the Geologic Map of the Fredonia 30’' x 60’ Quadrangle, Mohave and Coconino Counties, Northern Arizona

The database for the 1:100,000-scale Fredonia 30' x 60' quadrangle map was compiled from 32 1:24,000-scale maps. For clarity at 1:100,000-scale, some of the map units shown on the 1:24,000-scale maps were grouped together (see attached unit list) and some structural data were dropped; the database for the 1:24,000-scale maps is embedded in the 100,000-scale database. The full database is provided here in a large compressed file; (73.7 MB).

The Fredonia metadata report describes both 1:100,000- and 1:24,000-scale map elements. Users can view metadata either embedded within the geodatabase or in ASCII format outside the database.

The authors have generated geologic maps in PDF format of each of the 32 1:24,000-scale quadrangles. To view a 1:24,000-scale geologic map, click on a quadrangle in the index map below.
