As mentioned previously, the data used to create these maps are either the property of the USGS (US taxpayer), the State of Arizona, or the University of Arizona.  Although the 2D geologic maps and the 3-dimensional Bryce images are my creations, the data used to make the geologic maps and the DEM base maps are not.

Some of the geologic map views provided here will seem blurry, blocky, or structure lines oversized beyond utility.  A brief explanation is that these are artifacts created by the resolution necessities imposed on a desktop computer when transposing a file format of digitized, high-resolution files into a bitmap format.  Some of the files originally created with Surfer years ago are now inoperable, consequently, mitigation of this problem entails a complete re-creation of maps.  Because this is a long and arduous process, that operation is on the 'back burner' for now.  Additionally, the clarity of 3D renditions is restricted by virtual memory and run-time errors while processing high resolution images.  In short, 2-dimensional hardcopies in my possession do not include such defects, but the conversion difficulties of facilitating a precise and detailed cybermodel are proving to be the weak link of this project (one consolation is that this project was impossible just 10 years ago).

To view local geologic maps, view the annotated map to correlate the area name with the selections below.  Unit correlations utilized for this map are included here as a temporary measure.  Please be aware that this current table is unreliable for Quaternary deposits.  Late basin sediments vary spatially and temporally.  For example, terrace terrains flanking the CMCC all did not occur simultaneously even though basin-range topography had effected drainages; although terrace terrains may be similar in different localities, they may not have occurred simultaneously.  This shortcoming is admittedly my lack of a thorough knowledge of all Quaternary deposits and the difficulty inherent in attempting to cram diverse depositional facies into a few, neat, and convenient descriptive categories.  I urge students to consult William R. Dickinson's publication: Tectonic setting of faulted Tertiary strata associated with the Catalina Core Complex in southern AZ, GSA Special Paper 264, 1991.  Dickinson's excellent paper is, unlike the CMCC bible (Memoir 153), still available for purchase.

Most of the known geologic units in the CMCC are included here (a notable exception being a few units described by Force 1997).  This work is not sanctioned by any recognized authority on the CMCC.  Although I am quite sure about most correlations and/or units, I am aware of several errors/updates that have not been corrected.  Digitizing artifacts still plague the maps and are not indicated as such.  I will respond to inquiries of particular areas or specific units, but the errata will not be listed.  Basin deposits are not included as my current research is not rigorous enough to justify inclusion.  This project is currently ongoing and changes concerning polygons, lines, notation, et cetera...are yet to be included.
