It was 1943 and World War II raged on and Allied Forces were on the offensive in the Pacific and European theaters. Back home mineral exploration for critical minerals was essential to the war effort. As part of this effort, geologists of the Arizona Bureau of Mines meticulously mapped the geology of the copper-rich Superior mining area of Arizona.
Special Note:
On this, the 125th Anniversary of the Arizona Geological Survey (AZGS), we are celebrating the work of hundreds of geoscientists who struggled to understand and reconstruct Arizona’s geologic past. As part of that celebration, we are dedicating this issue of Arizona Geology to a retrospective display of articles published since the onset of our first formal publication serial, the Bulletin, in 1915. Because Arizona Geology is a vehicle for non-technical articles for a general audience, we largely focused on materials published over the past 42 years as part of our FieldNotes-Arizona Geology newsletter series.
