San Gabriel Mountains
The San Gabriel Mountains ( es, Sierra de San Gabriel) are a mountain range located in northern Los Angeles County and western San Bernardino County, California, United States. The mountain range is part of the Transverse Ranges and lies between the Los Angeles Basin and the Mojave Desert, with Interstate 5 to the west and Interstate 15 to the east. The range lies in, and is surrounded by, the Angeles and San Bernardino National Forests, with the San Andreas Fault as its northern border. The highest peak in the range is Mount San Antonio, commonly referred to as Mt. Baldy. Mount Wilson is another notable peak, known for the Mount Wilson Observatory and the antenna farm that houses many of the transmitters for local media. The observatory may be visited by the public. On October 10, 2014, President Obama designated the area the San Gabriel Mountains National Monument. The Trust for Public Land has protected more than of land in the San Gabriel Mountains, its foothi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alluvial Fans
An alluvial fan is an accumulation of sediments that fans outwards from a concentrated source of sediments, such as a narrow canyon emerging from an escarpment. They are characteristic of mountainous terrain in arid to semiarid climates, but are also found in more humid environments subject to intense rainfall and in areas of modern glaciation. They range in area from less than to almost . Alluvial fans typically form where flow emerges from a confined channel and is free to spread out and infiltrate the surface. This reduces the carrying capacity of the flow and results in deposition of sediments. The flow can take the form of infrequent debris flows or one or more ephemeral or perennial streams. Alluvial fans are common in the geologic record, such as in the Triassic basins of eastern North America and the New Red Sandstone of south Devon. Such fan deposits likely contain the largest accumulations of gravel in the geologic record. Alluvial fans have also been found on Mar ...

William Chaffey
William Benjamin Chaffey, CMG (21 October 1856 – 4 June 1926) was a Canadian engineer and irrigation planner who with his older brother George Chaffey developed what became the cities of Etiwanda, California, Ontario, California, and Upland, California in the United States of America, as well as the cities of Mildura, Victoria and the town of Renmark, South Australia, in Australia. Life Chaffey was born in Brockville, Ontario, Canada, the third son of George and his wife Anne ''née'' Legoe. The Chaffey brothers developed irrigation colonies, named by them Etiwanda and Ontario, on the Cucamonga Plain in the early 1880s. The brothers had bought land and water-rights at a low price and resold 10 acre (4 ha) blocks to settlers; a non-profit mutual irrigation company distributed water. Alfred Deakin, then a minister in the Victorian government and chairman of a royal commission on water supply, visited the irrigation areas of California in 1885 where he met George and W ...

George Chaffey
George Chaffey (28 January 1848 – 1 March 1932) was a Canadian–born engineer who with his brother William developed large parts of Southern California, including what became the community of Etiwanda and cities of Ontario, and Upland. They undertook similar developments in Australia which became the city of Mildura, and the town of Renmark and Paringa. Biography Chaffey was born in Brockville, Ontario and attended Kingston Grammar School on Lake Ontario. Chaffey's family was of Scottish heritage. Although not interested in schoolroom instruction, he read engineering books from the local library. Chaffey left school at 13 years of age, was fascinated by the shipbuilding yard of his father and became an apprentice marine engineer in May 1862. By 1880 he was well established as a designer of ships for Great Lakes traffic. While visiting his father in California that year, however, he became interested in the Riverside irrigation colony. By 1886 he and his brother William ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

San Andreas Fault
The San Andreas Fault is a continental transform fault that extends roughly through California. It forms the tectonic boundary between the Pacific Plate and the North American Plate, and its motion is right-lateral strike-slip (horizontal). The fault divides into three segments, each with different characteristics and a different degree of earthquake risk. The slip rate along the fault ranges from /yr. It was formed by a transform boundary. The fault was identified in 1895 by Professor Andrew Lawson of UC Berkeley, who discovered the northern zone. It is often described as having been named after San Andreas Lake, a small body of water that was formed in a valley between the two plates. However, according to some of his reports from 1895 and 1908, Lawson actually named it after the surrounding San Andreas Valley. Following the 1906 San Francisco earthquake, Lawson concluded that the fault extended all the way into southern California. In 1953, geologist Thomas Dibblee c ...

Fault (geology)
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A '' fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur ...

Thrust Fault
A thrust fault is a break in the Earth's crust, across which older rocks are pushed above younger rocks. Thrust geometry and nomenclature Reverse faults A thrust fault is a type of reverse fault that has a dip of 45 degrees or less. If the angle of the fault plane is lower (often less than 15 degrees from the horizontal) and the displacement of the overlying block is large (often in the kilometer range) the fault is called an ''overthrust'' or ''overthrust fault''. Erosion can remove part of the overlying block, creating a ''fenster'' (or '' window'') – when the underlying block is exposed only in a relatively small area. When erosion removes most of the overlying block, leaving island-like remnants resting on the lower block, the remnants are called ''klippen'' (singular '' klippe''). Blind thrust faults If the fault plane terminates before it reaches the Earth's surface, it is referred to as a ''blind thrust'' fault. Because of the lack of surface evidence, blind ...

Sierra Madre Fault Zone
Situated at the boundary to the San Gabriel Valley and San Fernando Valley, the Sierra Madre Fault Zone (also known as the Sierra Madre-Cucamonga Fault) runs along the southern edge of the San Gabriel Mountains for a total of , where the northwesternmost comprises the San Fernando Fault (the section responsible for the 1971 San Fernando earthquake). A 1980s paleoseismic study that included a trench investigation and mapping revealed that a major earthquake had most likely not occurred to the east of the San Fernando rupture area for at least the last several thousand, and possibly the last 11,000 years. The 1971 event was the first in a series ( 1987 Whittier Narrows, 1991 Sierra Madre, 1994 Northridge) of damaging earthquakes which have occurred on reverse faults in the Los Angeles area. The events triggered discussions concerning the largest magnitude earthquake that could be generated by one of the faults, especially in the Transverse Ranges, but the focal point of earthqua ...

Santa Ana Winds
The Santa Ana winds (sometimes devil winds) "Scholars who have looked into the name's origins generally agree that it derives from Santa Ana Canyon, the portal where the Santa Ana River -- as well as a congested Riverside (CA-91) Freeway -- leaves Riverside County and enters Orange County. When the Santa Anas blow, winds can reach exceptional speeds in this narrow gap between the Puente Hills and Santa Ana Mountains." are strong, extremely dry downslope winds that originate inland and affect coastal Southern California and northern Baja California. They originate from cool, dry high-pressure air masses in the Great Basin. Santa Ana winds are known for the hot, dry weather that they bring in autumn (often the hottest of the year), but they can also arise at other times of the year. They often bring the lowest relative humidities of the year to coastal Southern California, and “beautifully clear skies.” These low humidities, combined with the warm, compressionally-heated air ...

Inland Empire (California)
The Inland Empire (IE) is a metropolitan area and region inland of and adjacent to coastal Southern California, centering around the cities of San Bernardino and Riverside, and bordering Los Angeles County to the west. It includes the cities of western Riverside County and southwestern San Bernardino County, and is considered to include the desert communities of the Coachella and Victor Valleys, respectively on the other sides of the San Gorgonio Pass and San Bernardino Mountains from the Santa Ana River watershed that forms the bulk of the Inland Empire; a much broader definition includes all of Riverside and San Bernardino counties. The combined land area of the counties of the Inland Empire is larger than ten U.S. states—West Virginia, Maryland, Hawaii, Massachusetts, Vermont, New Hampshire, New Jersey, Connecticut, Delaware and Rhode Island—and slightly smaller than the combined area of the five smallest U.S. states (New Hampshire through Rhode Island).
