Edited by Philip A. Pearthree

This volume, prepared as part of the Geological Society of America Annual Meeting in Phoenix, includes eld guides covering aspects of the spectacular geology of southwestern North America. Field guides tackle the geology of the southern Colorado Plateau, from paleoenvironments of Petri ed Forest National Park, to Jurassic sand dunes of southern Utah, to the San Francisco Volcanic Field, to awesome Grand Canyon. Appropriately for the 50th anniversary of the rst lunar landing, one trip visits sites in northern Arizona that helped prepare astronauts for their missions. Several guides address aspects of the Proterozoic to Cenozoic tectonic development of the Transition Zone between the Colorado Plateau and the Basin and Range. Exploring the Basin and Range, guides feature Laramide tectonism and ore deposit In Press development, features associated with large-magnitude Ceno- zoic extensional tectonism, large Miocene volcanic centers in northwestern Arizona, and tectonism and development of the lower Colorado River. Three eld guides explore various aspects of northwest- ern Mexico, including tectonics and ore deposits of Sonora, fauna and paleoenvironments of Colorado River delta deposits, and volcanism in central Baja California. Finally, a guide analyzes anthropogenic earth ssures that have developed in the Phoenix metropolitan area. FLD055, 553 p., ISBN 9780813700557 | IN PRESS |

The Grand Canyon State welcomes the Geological Society of America to our capital city of Phoenix for the first time in more than three decades. It’s an especially auspicious year for GSA to come here, as 2019 marks both the 150th anniversary of John Wesley Powell’s first expedition through Grand Canyon and the 100th anniversary of Grand Canyon National Park! Arizona is indeed a land of textbook geology, where you can set your feet, hands, senses, and camera on the exposed rock record of nearly two billion years of deep time. As symbolized in the logo for the 2019 Annual Meeting, Arizona has tremendous geologic, topographic, climatic, and ecological diversity: from the Sonoran Steve Semken Desert landscapes of the rugged and arid Basin and Range in the south where Phoenix is located, through the mountainous Transition Zone, north to the high-elevation Colorado Plateau with its colorful, fossil-rich layer- cake strata incised a mile deep in the mighty Grand Canyon. Owing to this great natural diversity, Arizona is often referred to as “many states in one.” We produce more copper than all but a few nations, let alone any other U.S. state. We are home to 22 National Parks, Monuments, and Historic Sites, and wonderful state and local parks as well. The record of human history and culture in Arizona dates back many millennia, and 21 contemporary Native American nations know it as their homeland. Arizona’s history and culture have also long benefited from our proximity to and friendly relations with México. We hope you are taking advantage of one (or more) of the 28 scientific field trips being offered, with their many opportunities to explore and enjoy the geology, geography, and scenery of Arizona and adjoining areas of the Southwest. Today’s Phoenix is decidedly different from the town that hosted the GSA Annual Meeting in 1987. We are now the fifth-largest city in the United States: a sunny, friendly, exciting, culturally rich, proudly Southwestern place. Amenities range from the lovely landscapes of the Desert Botanical Garden to the world’s largest collec- tion of Native American art at the Heard Museum, to famed architect Frank Lloyd Wright’s fascinating western home base at Taliesin West, to the climate-controlled Chase Field just blocks from the Convention Center, where you can come watch the Arizona Diamondbacks play during a home series that coincides with our meeting! Phoenix is a gastronomic paradise, renowned for its multiregional Mexican, Latin American, and Indigenous cuisines, to be sure, but also home to scores of other diverse and delightful restaurants and pubs—including a pizzeria that many national food critics consider to be among the very best in the USA! Our light-rail and bus systems make it easy to get around, and Sky Harbor Airport, served by all major carriers, is a very short hop from downtown. The Annual Meeting technical program features 31 short courses and workshops, six Pardee Symposia, and 200 topical sessions. We’ll also have plenty of activities and informal gatherings, and as always, a dynamic exhibit hall. Students and early career geoscientists will find much here to engage and interest them. Welcome one and all to the Valley of the Sun!

Message from the GSA President and Executive Director

We welcome you to GSA’s 2019 Annual Meeting and Exposition! This will be an inspiring meeting, and we thank all the organizers and sponsors. It’s the 100th Anniversary of the iconic geologic wonder, the Grand Canyon, becoming a U.S. National Park and so having the meeting in Phoenix seems very appropriate indeed. Here you will have a wonderful opportunity to learn about and visit the geological and ecological diversity of the American Southwest, including Grand Canyon itself and dozens of other national parks and monuments. We trust you are planning to attend some of the 28 field trips, 200 topical sessions and specialty lectures, and six Pardee Symposia covering the gamut of our subdisciplines and dealing with geoscience topics ranging from applications to curiosity-driven research. General Chair Steve Semken, Technical Program Chairs Amy Brock-Hon and Kevin Mickus, Field Trip Chair Phil Pearthree, and all the local organizing committee did a wonderful job in arranging this special meeting. Our Associated Societies and GSA Scientific Divisions have cosponsored sessions, adding their expertise to the mix, ranging from critical climate change issues to details on the evolution of Earth’s crust to novel methods in applied geophysics and other tools. Short courses also cover a broad range of topics including the pedagogical. Students and early career professionals will have ample opportunities to take advantage of GSA mentoring and programs to get career advice and interview for jobs offered by industry, government, and academia through our expanded GeoCareers recruitment program. Visit the GSA GeoCareers Center to mingle, meet mentors and potential employers, or just find a relaxing place to discuss the meeting with friends. You can renew old acquaintanceships and make new friendships within our GSA community of geoscien- tists and friends at our opening reception in the expansive exhibit hall and at multiple university alumni receptions. We invite you to indulge in the smorgasbord of cuisines, museums, and entertainment venues in Phoenix and, if time allows, visit the multitude of national and other parks in close proximity during what promises to be good seasonal weather. Do come to the Presidential Address & Awards Ceremony Sunday beginning at noon. Join us in congratulating the 2019 GSA Medalists and Awardees as well as the new class of GSA Fellows. There, President Don Siegel will offer his vision of how geoscience opportunities may change in a future of serious climate disruption. Multidisciplinary opportunities should abound for those geoscientists who choose to participate in adaptation efforts to mitigate the effects. We invite you to attend the GSA Strategic Plan Town Hall to hear about GSA’s directions over the next decade. Please also attend the Ethics & Compliance Town Hall for an update on GSA’s revised Code of Ethics. We look forward to greeting as many of you as possible, listening to you share your research and results, and making new connections at this meeting.

The Edwards Aquifer: The Past, Present, and Future of a Vital Water Resource Edited by John M. Sharp Jr., Ronald T. Green, The Edwards aquifer system is one of the great and Geary M. Schindel karstic aquifer systems of the world. It supplies water for more than 2 million people and for agri- cultural, municipal, industrial, and recreational uses. The Edwards (Balcones Fault Zone) Aquifer in the San Antonio, Texas, area was the fi rst to be Memoir 215 designated a sole source aquifer by the Environ- mental Protection Agency in 1975. The Edwards Aquifer also hosts unique groundwater, cave, and spring ecosystems. This 27-chapter memoir re- views the current state of knowledge, current and emerging challenges to wise use of the aquifer system, and some of the technologies that must be adopted to address these challenges.
