Part 24 [see also Special Note at bottom pertaining to the Appendix]
GEOLOGIC AND SPECIAL TOPOGRAPHIC MAPS IN THE GRAND CANYON REGION -- WITH GUIDES TO USGS TOPOGRAPHIC QUADRANGLES
Separately published geologic, geodetic, and special topographic maps of the Grand Canyon region; with summary guides to U.S. Geological Survey topographical quadrangles in the region
OVERVIEW. This part of the bibliography lists only separately published maps, and selected atlas sheets. Regional maps that embrace the Grand Canyon area are included.
Appendix to Part 24: Graphical and other guides to U.S. Geological Survey topographical quadrangles in the greater Grand Canyon region
The appendix provides graphical and itemized guides to the topographic maps of the lower Colorado River region, produced by the U.S. Geological Survey. Both legacy paper map guides and current online guides are referred to. Graphical guides illustrate the geographical arrangement of named topographical quadrangles. Itemized guides list, either alphabetically or by special geographical order, the quadrangle names within the region. These lists provide the names of quadrangles by which researchers may refer to either in physical map collections or in the U.S. Geological Survey’s very comprehensive collections of digitized historic and current maps. The alphabetical lists are provided so that users who wish to acquire complete sets may locate the maps easily by name.
SPECIAL NOTE: In the APPENDIX the map embedded in the PDF that depicts the system of 7.5-minute topographic map quadrangles in the Grand Canyon region (which had been replicated from an old-style paper copy) does not sufficiently display the quadrangle names when the PDF is enlarged.
