Introduction San Andreas Fault: an Overview
Introduction This volume is a general geology field guide to the San Andreas Fault in the San Francisco Bay Area. The first section provides a brief overview of the San Andreas Fault in context to regional California geology, the Bay Area, and earthquake history with emphasis of the section of the fault that ruptured in the Great San Francisco Earthquake of 1906. This first section also contains information useful for discussion and making field observations associated with fault- related landforms, landslides and mass-wasting features, and the plant ecology in the study region. The second section contains field trips and recommended hikes on public lands in the Santa Cruz Mountains, along the San Mateo Coast, and at Point Reyes National Seashore. These trips provide access to the San Andreas Fault and associated faults, and to significant rock exposures and landforms in the vicinity. Note that more stops are provided in each of the sections than might be possible to visit in a day. The extra material is intended to provide optional choices to visit in a region with a wealth of natural resources, and to support discussions and provide information about additional field exploration in the Santa Cruz Mountains region. An early version of the guidebook was used in conjunction with the Pacific SEPM 2004 Fall Field Trip. Selected references provide a more technical and exhaustive overview of the fault system and geology in this field area; for instance, see USGS Professional Paper 1550-E (Wells, 2004). San Andreas Fault: An Overview The catastrophe caused by the 1906 earthquake in the San Francisco region started the study of earthquakes and California geology in earnest. -
THE EXPLORERS by Richard F. Pourade CHAPTER ONE: BEFORE
THE EXPLORERS By Richard F. Pourade CHAPTER ONE: BEFORE THE EXPLORERS San Diego was a well populated area before the first Spanish explorers arrived. The climate was wetter and perhaps warmer, and the land more wooded than now. The remnant of a great inland lake covered most of Imperial Valley. The San Diego River wandered back and forth over the broad delta it had formed between Point Loma and Old Town, alternately emptying into Mission Bay and San Diego Bay. The natural food supply was so abundant that the state as a whole supported an Indian population far greater than any equal area in the United States. The native population of the southern counties alone must have been at least 10,000. The early maps made of San Diego Bay by the Spanish explorers show the same general configuration as of today, except, of course, for the many changes in the shoreline made by dredging and filling in recent years. The maps, crudely drawn without proper surveys, vary considerably in detail. Thousands of years ago, in the late part of the Ice Age, Point Loma was an island, as were Coronado and North Island. Coronado used to be known as South Island. There was no bay, as we think of it now. A slightly curving coastline was protected by the three islands, of which, of course, Point Loma was by far the largest. What we now know as Crown Point in Mission Bay was a small peninsula projecting into the ocean. On the mainland, the San Diego and Linda Vista mesas were one continuous land mass. -

Historic Context Statement City of Benicia February 2011 Benicia, CA
Historic Context Statement City of Benicia February 2011 Benicia, CA Prepared for City of Benicia Department of Public Works & Community Development Prepared by page & turnbull, inc. 1000 Sansome Street, Ste. 200, San Francisco CA 94111 415.362.5154 / www.page-turnbull.com Benicia Historic Context Statement FOREWORD “Benicia is a very pretty place; the situation is well chosen, the land gradually sloping back from the water, with ample space for the spread of the town. The anchorage is excellent, vessels of the largest size being able to tie so near shore as to land goods without lightering. The back country, including the Napa and Sonoma Valleys, is one of the finest agriculture districts in California. Notwithstanding these advantages, Benicia must always remain inferior in commercial advantages, both to San Francisco and Sacramento City.”1 So wrote Bayard Taylor in 1850, less than three years after Benicia’s founding, and another three years before the city would—at least briefly—serve as the capital of California. In the century that followed, Taylor’s assessment was echoed by many authors—that although Benicia had all the ingredients for a great metropolis, it was destined to remain in the shadow of others. Yet these assessments only tell a half truth. While Benicia never became the great commercial center envisioned by its founders, its role in Northern California history is nevertheless one that far outstrips the scale of its geography or the number of its citizens. Benicia gave rise to the first large industrial works in California, hosted the largest train ferries ever constructed, and housed the West Coast’s primary ordnance facility for over 100 years. -

San Mateo County
Steelhead/rainbow trout resources of San Mateo County San Pedro San Pedro Creek flows northwesterly, entering the Pacific Ocean at Pacifica State Beach. It drains a watershed about eight square miles in area. The upper portions of the drainage contain springs (feeding the south and middle forks) that produce perennial flow in the creek. Documents with information regarding steelhead in the San Pedro Creek watershed may refer to the North Fork San Pedro Creek and the Sanchez Fork. For purposes of this report, these tributaries are considered as part of the mainstem. A 1912 letter regarding San Mateo County streams indicates that San Pedro Creek was stocked. A fishway also is noted on the creek (Smith 1912). Titus et al. (in prep.) note DFG records of steelhead spawning in the creek in 1941. In 1968, DFG staff estimated that the San Pedro Creek steelhead run consisted of 100 individuals (Wood 1968). A 1973 stream survey report notes, “Spawning habitat is a limiting factor for steelhead” (DFG 1973a, p. 2). The report called the steelhead resources of San Pedro Creek “viable and important” but cited passage at culverts, summer water diversion, and urbanization effects on the stream channel and watershed hydrology as placing “the long-term survival of the steelhead resource in question”(DFG 1973a, p. 5). The lower portions of San Pedro Creek were surveyed during the spring and summer of 1989. Three O. mykiss year classes were observed during the study throughout the lower creek. Researchers noticed “a marked exodus from the lower creek during the late summer” of yearling and age 2+ individuals, many of which showed “typical smolt characteristics” (Sullivan 1990). -
