Natural Disasters, Past and Impending, in the Eastern San Gabriel
April 18, 2009 Field Trip #4: Natural Hazards, Past and Impending, in the Eastern San Gabriel Mountains Jonathan A. Nourse Department of Geological Sciences California State Polytechnic University 3801 West Temple Avenue Pomona, CA 91768 Introduction The eastern San Gabriel Mountains present a spectacular outdoor laboratory for studying the causes and consequences of natural hazards that include earthquakes, floods, landslides, and fires. Since 1991 I have utilized the San Antonio Canyon region as a convenient place to educate Cal Poly Pomona students enrolled in my Natural Disasters, Engineering Geology, Structural Geology, Tectonics, Groundwater Geology and Optical Mineralogy courses. The area has also provided world-class field trip sites for the Geological Society of America, the Thomas W. Dibblee Foundation and NAGT. This guidebook includes excerpts from several previous field trip guides for which I have been principle or contributing author (Nourse, et al., 1998; Trent and Nourse, 2001; Trent et al., 2001, Nourse, 2003). The oblique aerial view of Figure 1 highlights the San Gabriel Mountains block, uplifted along the Sierra Madre-Cucamonga frontal thrust system and dissected by left-lateral and right-lateral strike slip faults. Our plan for today is to begin the trip at San Antonio Dam near the intersection of the Cucamonga, San Jose and San Antonio Canyon faults. Working our way up the Mt. Baldy Road, we shall view field evidence of floods, landslides and debris flows that have resulted from interplay between steep topography, severe weather conditions, and major earthquakes. Effects of the devastating fire of 2003 are also prominent. We will discuss impacts of the floods of 1938, 1969, and 2005 on human structures such as dams, roads and buildings. -

THE YOSEMITE by John Muir CHAPTER I The
THE YOSEMITE By John Muir CHAPTER I The Approach to the Valley When I set out on the long excursion that finally led to California I wandered afoot and alone, from Indiana to the Gulf of Mexico, with a plant-press on my back, holding a generally southward course, like the birds when they are going from summer to winter. From the west coast of Florida I crossed the gulf to Cuba, enjoyed the rich tropical flora there for a few months, intending to go thence to the north end of South America, make my way through the woods to the headwaters of the Amazon, and float down that grand river to the ocean. But I was unable to find a ship bound for South America--fortunately perhaps, for I had incredibly little money for so long a trip and had not yet fully recovered from a fever caught in the Florida swamps. Therefore I decided to visit California for a year or two to see its wonderful flora and the famous Yosemite Valley. All the world was before me and every day was a holiday, so it did not seem important to which one of the world's wildernesses I first should wander. Arriving by the Panama steamer, I stopped one day in San Francisco and then inquired for the nearest way out of town. "But where do you want to go?" asked the man to whom I had applied for this important information. "To any place that is wild," I said. This reply startled him. He seemed to fear I might be crazy and therefore the sooner I was out of town the better, so he directed me to the Oakland ferry. -

Appendix D Building Descriptions and Climate Zones
Appendix D Building Descriptions and Climate Zones APPENDIX D: Building Descriptions The purpose of the Building Descriptions is to assist the user in selecting an appropriate type of building when using the Air Conditioning estimating tools. The selected building type should be the one that most closely matches the actual project. These summaries provide the user with the inputs for the typical buildings. Minor variations from these inputs will occur based on differences in building vintage and climate zone. The Building Descriptions are referenced from the 2004-2005 Database for Energy Efficiency Resources (DEER) Update Study. It should be noted that the user is required to provide certain inputs for the user’s specific building (e.g. actual conditioned area, city, operating hours, economy cycle, new AC system and new AC system efficiency). The remaining inputs are approximations of the building and are deemed acceptable to the user. If none of the typical building models are determined to be a fair approximation then the user has the option to use the Custom Building approach. The Custom Building option instructs the user how to initiate the Engage Software. The Engage Software is a stand-alone, DOE2 based modeling program.

In advance of the plan’s release, the NPS is providing the Tuolumne River Values and Baseline Conditions chapter as a preview into one of the plan’s most foundational elements. Sharing the baseline information in advance of the plan will give members of the public an understanding of river conditions today and specific issues that will be explored in the Tuolumne River Plan. Public comments on all elements of the Tuolumne River Plan, including the baseline conditions chapter, will be accepted when it is released for review this summer. What follows is a description of the unique values that make the Tuolumne stand apart from all other rivers in the nation. This chapter also provides a snapshot in time, documenting overall conditions and implications for future management. In particular the baseline chapter examines, • What are the outstandingly remarkable values that make the Tuolumne River worthy of special protection under the Wild and Scenic Rivers Act (WSRA)? • What do we know about the condition of these values (in addition to water quality and free-flow), both at time of designation in 1984 and -
