On 14-15 November, Jon Spencer, Phil Pearthree and Jordan Bright (Univ of AZ Ph.D. candidate) guided 30 AGS members and guests on an excursion in the northern Plomosa Mountains and to view the Bouse Formation in the Blythe Basin. The weather splendid, the rocks and Bouse outcrops brilliant, the audience engaged and argumentative (in a positive way), and the trip a smashing success.
A final draft of the field guide is available here.
On the following Tuesday, we canvassed trip participants for their experience. Over 75% completed and submitted an online survey published at SurveyMonkey.com. We hope these data will inform future field trips.
The survey results and comments of those surveyed are available here.

Karen Wenrich and Bob Cummings getting an autographed copy of Dave Lowell's autobiography
The Arizona Geological Society thanks J. David Lowell for attending the September 1, 2015 dinner meeting, where he autographed copies of his recently published autobiography, Intrepid Explorer: The Autobiography of the World's Best Mine Finder.
A native Arizonan, whose family roots date from territorial days, J. David Lowell was raised on a ranch near Nogales, Arizona to become one of the world's most successful exploration geologists. He received a B.S. degree in Mining Engineering from the University of Arizona in 1949 and a M.S. degree in Geology from Stanford in 1957.
He has personally discovered more copper than anyone in history, contributing to the discoveries of the Kalamazoo, Vekol Hills and Casa Grande West deposits in Arizona, the JA Deposit in British Columbia, the Dizon and Far Southeast deposits in the Philippines, and the La Escondida, Zaldivar and Leonore deposits in Chile. He is also personally responsible for the discovery of the San Cristobal Au-Ag mine in Chile and the 8-million ounce Pierina gold deposit in Peru.
Dave Lowell has published more than 50 articles, including one of which he co-authored with John Guilbert in 1970 that defines the Lowell-Guilbert porphyry copper model. This work remains a standard reference for exploration geologists, today. Dave Lowell is also a
former member of the Arizona Geological Society and served as its president in 1966.
The geosciences community lost a giant on July 21, 2015. Dr. William (Bill) Dickinson, Professor Emeritus at the University of Arizona, passed away apparently in his sleep, while in his hotel room in Nuku'alofa, Tonga. Bill was working with archaeologist David Burley and his graduate student on the geology of some archaeological sites in Tonga.
Bill Dickinson's contributions to the geosciences are legendary. He was a true pioneer in the field of plate tectonic theory and its implications for geology in the western United States. As a longtime member of the Arizona Geological Society, he co-organized the 1981 AGS symposium on “Relations of Tectonics to Ore Deposits in the Southern Cordillera” the proceedings of which were published as AGS Digest 14. He also co-edited AGS Digest 18, “Mesozoic Rocks of Southern Arizona and Adjacent Area.” AGS Digest 22, “Ores and Orogenesis: Circum-Pacific Tectonics, Geologic Evolution, and Ore Deposits” was dedicated in his honor.
We offer our sincere condolences to Bill's family, friends and colleagues. Bill was a great teacher, who touched and influenced many. He will be missed, but his contributions to geology will endure. May he rest in peace.
