Mount Umunhum
Mount Umunhum (Ohlone for "Resting Place of the Hummingbird") is a peak in the Santa Cruz Mountains, located in Santa Clara County, California. It is the fourth-highest peak in the Santa Cruz Mountains, after Loma Prieta, Crystal Peak, and Mt. Chual. Most of the mountain is located within the Sierra Azul Open Space Preserve. Geology Mt. Umunhum consists of a geologic formation that is known as the ''Coast Range Ophiolite.'' This ophiolite is a piece of Middle Jurassic oceanic crust and mantle that has been obducted onto land and largely been converted to serpentinite. It has been extensively faulted and diapirically uplifted and eroded to form Mt. Umunhum and extensive outcrop areas throughout the Santa Cruz Mountain foothills and elsewhere. The Coast Range Ophiolite is also known to underlie the rocks of the Great Valley throughout central California. The exposure on the northeast face of Mt. Umunhum is one of the best Bay Area exposures of the Coast Range Ophiolite.Bailey, E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Santa Cruz Mountains
The Santa Cruz Mountains, part of the Pacific Coast Ranges, are a mountain range in central and Northern California, United States. They form a ridge down the San Francisco Peninsula, south of San Francisco. They separate the Pacific Ocean from the San Francisco Bay and the Santa Clara Valley, and continue south to the Central Coast, bordering Monterey Bay and ending at the Salinas Valley. The range passes through the counties of San Mateo, Santa Clara, Santa Cruz, San Benito and Monterey, with the Pajaro River forming the southern boundary. Geography The northernmost portion of the Santa Cruz Mountains, north of Half Moon Bay Road ( SR 92), is known as Montara Mountain; the middle portion is the Sierra Morena, which includes a summit called Sierra Morena, and extends south to a gap at Lexington Reservoir; south of the gap, the mountain range is known as the Sierra Azul. The highest point in the range is Loma Prieta Peak, west of Morgan Hill, with a height of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredth an ...

Mountain Range
A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. Mountain ranges are usually segmented by Highland (geography), highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same Structural geology, geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example Thrust fault, thrust sheets, Fault-block mountain, uplifted blocks, Fold (geology), fold mountains, and vol ...

Mountains Of Santa Clara County, California
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
