Geology and Geologic Hazards of Northwestern Baja's Gold Coast and the Agua Blanca Fault cover
Geology of the Coyote Mountains.
Southern California

Randall Wagner, ed. (2015)
ISBN: 9781941384213

-------List Price 2015 $35-------



Anyone interested in the rich and complex geology of the Coyote Mountains will find this book useful for interpreting the Paleozoic metamorphic rocks of a rifted continental margin, Mesozoic igneous rocks from a magmatic arc, and Cenozoic continental red beds and volcanic rocks overlain by marine, riverine, and lake sequences. All these capped by fanglomerates and cut by faults. No other location in the region showcases such diverse rock types and so much geologic time in such a small area. As USGS geologist Walter Mendenhall said in 1910, the Coyote Mountains' "exposures and structures are so clear that its geology will be an open book to the fortunate student to whom falls the pleasant task of deciphering it in detail."
