This monograph is the most comprehensive treatment available of the geology of the Santa Catalina Mountains north of Tucson, expanding greatly on classic older descriptions of the southern Catalinas. The study treats the entire range with a cross-sectional emphasis to clarify relations among the mylonitic core-complex aspects to the south, passing northward through voluminous Tertiary granitic rocks and an older deformed and metamorphosed zone into a tilted relic of the Plateau. New rock units such as Precambrian glaciomarine deposits are introduced, and the mineral-resource character and potential of each segment of the range is described. The book includes a full-color 1:48,000 geologic map of an 11 x 48 km transect through the range, oriented to permit reconstruction of the jigsaw puzzle produced by Tertiary crustal stretching. Three other detailed maps and descriptions of key localities make the monograph a self-guided tour through the geologic history of the range.

This volume includes five geologic field-trip guides in the Los Angeles region associated with the 2020 GSA Cordilleran Section Meeting that was scheduled for May 2020, in Pasadena, California. The guides are organized in a generally counterclockwise order around the Los Angeles Basin. The first guide by Burgette et al. provides new slip rates, age constraints, and observations of the active Sierra Madre fault zone that borders the northern side of the San Gabriel and San Fernando Valleys. The Nourse et al. guide takes a new look at the San Gabriel Mountains from a basement and geomorphologic perspective. Further west, Keller et al. provide one of the first published field-trip guides focused on the 9 January 2018 Montecito debris flows that caused 23 deaths. The volume then moves south to Santa Cruz Island, where Davis et al. provide an updated review of the island’s geology within the California borderlands. The final guide returns to the east, where Platt et al. present the unique geology of Santa Catalina Island with a focus on the subduction-related Catalina Schist.

Once plentiful in the mountains of southern Arizona, by the 1990s desert bighorn sheep were wiped out in the Pusch Ridge Wilderness of the Santa Catalina Mountains as a result of habitat loss and alteration. This book uses their history and population decline as a case study in human alteration of wildlife habitat. When human encroachment had driven the herd to extinction, wildlife managers launched a major and controversial effort to reestablish this population. For more than forty years Paul R. Krausman directed studies of the Pusch Wilderness population of these iconic animals, located in the mountainous outskirts of Tucson. The story he tells here reveals the complex relationships between politics and biology in wildlife conservation. His account of the evolution of wildlife conservation practices includes discussions of techniques and of human attitudes toward predators, fire, and their management.

Excerpt from The Geology of Santa Catalina Island Santa Catalina Island, one of the group known as the Channel Islands, off the coast of southern California, lies about 20 miles south of San Pedro Hill, the nearest point on the mainland. At about the same distance south of Santa Catalina lies the island of San Clemente, the three eleva tions being nearly in a straight line. The general trend of the island is northwest by west. Its length is approximately twenty-one miles, with an aver age width Of three miles, varying from half a mile at the isthmus to about eight miles in the widest part. The pre vailing winds are from west to southwest, and the waves exert their greatest force on the southwest face of the island. They are, however, by no means inactive on the landward side, as is shown by the rapidly retreating shore-line. The only settlements on the island are the summer resort at Avalon, and a small community at the isthmus. Besides these, a few solitary houses are located at different points on the coast. The island was once occupied by Indians, and evi deuces of their camps occur frequently in the form of shell fragments, rounded stone implements, and earth blackened by the camp fires. Owing to its ruggedness and the scarcity of water, the island is habitable in only afew places. There are half a dozen or more springs and creeks which do not dry up during the summer, and a few wells supply the other points. All the water is decidedly alkaline.
