EXCLUSIVE to APCRP: Volume 1 of "Mine Locations in La Paz and Yuma Counties", is currently available through APCRP. If you would like to receive an ELECTRONIC copy by email, you may do so by sending a check for $25.00 plus $5.00 shipping and handling to Neal (see contact information at the end of this document).


APCRP members know that much of the work we do (research, location, documentation and restoration) places us in contact with the territorial history of mines, mining camps and settlements.  It was the prospect of riches in the gold fields that attracted most of the early pioneers to this inhospitable and dangerous land in the mid-1800’s and after, and it is virtually impossible to develop a full understanding and appreciation of an abandoned pioneer cemetery or grave cluster without acknowledging the direct or indirect connections between that site and mine history.


For myself, this recognition prompted me to do more research into the locations and names of mines in each mountain range and county in Arizona.  I have now completed the inventory of La Paz and Yuma counties and hope to finish the Yavapai list in the very near future.  Preliminary work has already commenced on Mohave and Maricopa Counties, and others will follow as time permits.   The first volume, “La Paz & Yuma County Mine Locations”, contains 1,870 mine workings.  Of these, 938 are named mine locations; including many mines that are either not named on USGS maps or that do not appear on maps at all.  For example, the three mines shown below are not named by the USGS:


"Unnamed" Mines in the Harquahala Mountains


Not surprisingly, even 1,870 mine workings is not a complete rendering of the inventory of potential sites.  There are several thousand more “prospects” that failed to demonstrate enough potential to merit further development into working mines.  Unfortunately, there are many other mines whose names are known, but their locations are now lost.  Nevertheless, this compilation represents the most extensive listing that I have seen in a single document.


Mountain ranges are where you find most mines in Arizona.  This is true because the uplifting of continental plates and the violent nature of volcanism either exposed or concentrated the veins of ore in ways that made it relatively easy to locate.  Mountain ranges are far older than the arbitrary placement of county political boundaries.  For example, the Harquahala Mountains stretch from western Maricopa County into La Paz County, and the Kofa and Trigo Mountains overlay La Paz and Yuma Counties.  For this reason I have focused my documentation on the mountain ranges.  Thus, mines in the western Maricopa portion of the Harquahalas are included in this listing – even though this volume title represents La Paz and Yuma.  This means there are 162 named mines and unnamed mine workings in western Maricopa County that are included.


Most reference documents provide a single set of GPS coordinates to represent a mine, even though there might be a half-dozen or more workings (shafts, adits, surface cuts or open pits).  This document breaks with that frustrating tradition and lists the coordinates of every identifiable mine entrance.  Rather than place the coordinates “near” the mine, I have attempted to place them directly at the shaft or adit entrance.  The exceptions are those mines that relied exclusively on open pit operations where the coordinates (waypoints) will be found at the mine trail entrance to the site.  Otherwise, the only constraint on accuracy is that placed upon a GPS unit or mapping software.  Generally speaking, every mine opening contained in this list should be within 20 feet of accuracy.


In addition to GPS coordinates, each entry includes the section, Township and Range for the mine.  Why use this anachronistic method?  The simplest reason is that Township & Range are useful in separating one mine from another through historical documentation – especially where there was a high concentration of activity.  Each named mine entry includes a brief description of the workings and date of origin, if known. 


Finally, this document resolves thirty mines that have “conflicted location descriptions.”  Simply stated, the USGS and other reference sources occasionally got it wrong, and I have made every effort to correct the location descriptions when these errors were found.


In its current state, the “La Paz and Yuma County Mine Locations” document is 113 pages in length.  When it is (eventually) published in book form it will include selected photos and maps showing the location of many of the mines, including those that are not named on USGS maps.  It is difficult to estimate the final number of pages, but it will probably exceed 200.  The published book will also include a means to obtain all GPS coordinates in a “.gpx” file format for use with National Geographic TOPO or De Lorme mapping software.


It is my hope this form of documentation will be useful for your research of historic mines and pioneer sites. As I expand the coverage to other counties, you can expect the addition of several thousand more mines. Special thanks to Kathy Block for her help and enthusiasm during the collection of material for La Paz, Yuma and western Maricopa counties.
