California State Route 24
STATE ROUTE 24 (SR 24) in the U.S. state of California is a heavily traveled east–west freeway in the eastern side of the San Francisco Bay Area of northern California that runs from the Interstate 580 / Interstate 980 interchange (just east of the MacArthur Maze ) in Oakland , and through the Caldecott Tunnel under the Berkeley Hills , to the Interstate 680 junction in Walnut Creek . It lies in Alameda County , where it is highly urban, and Contra Costa County , where it passes through wooded hillsides and suburbs. CONTENTS * 1 Route description * 2 History * 3 Exit list * 4 See also * 5 References * 6 External links ROUTE DESCRIPTIONThis route is part of the California Freeway and Expressway System and is eligible for the State Scenic Highway System . Caltrans has only designated it as a scenic highway between the eastern end of the Caldecott Tunnel and I-680 , however. SR 24 is designated as both the GROVE SHAFTER FREEWAY (named after streets the route travels along - Grove Street was later renamed Martin Luther King Jr. Way) and the William Byron Rumford Freeway (honoring the first African American elected to a state public office) from the Caldecott Tunnel to the I-580 interchange segment of the MacArthur Maze , continuing henceforth as I-980 to the terminus with I-880

Summit
A SUMMIT is a point on a surface that is higher in elevation than all points immediately adjacent to it. Mathematically , a summit is a local maximum in elevation. The topographic terms "acme", "apex", "peak" , and "zenith " are synonymous . CONTENTS* 1 Definition * 1.1 Western United States * 2 See also * 3 References * 4 External links DEFINITIONThe term "summit" is generally used only for a mountain peak with some significant amount of topographic prominence (height above the lowest point en route to the nearest higher peak) or topographic isolation (distance from the nearest point of higher elevation); for example, a boulder next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered _subsummits_ (or _subpeaks_) of the higher peak, and are considered as part of the same mountain. The UIAA definition is that a summit is independent if it has a prominence of 30 metres (98 ft ) or more; it is a mountain if it has a prominence of at least 300 metres (980 ft). This can be summarised as follows: TERM PROMINENCE ISOLATION Subpeak < 30 m ? m Independent peak or summit 30 m or more ? m Mountain 300 m or more ? mA pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may also refer to the highest point along a line, trail, or route

. It held fixed the height of the primary tidal bench mark, referenced to the International Great Lakes Datum of 1985 local mean sea level height value, at Rimouski , Quebec
Quebec
, Canada
Canada
. Additional tidal bench mark elevations were not used due to the demonstrated variations in sea surface topography, i.e., that mean sea level is not the same equipotential surface at all tidal bench marks. The definition of NAVD 88 uses the Helmert orthometric height, which calculates the location of the geoid (which approximates sea level) from modeled local gravity. The NAVD 88 model is based on then-available measurements, and remains fixed despite later improved geoid models. NAVD 88 replaced the National Geodetic Vertical Datum of 1929 (NGVD 29), previously known as the Sea Level Datum of 1929

Topographic Prominence
In topography , PROMINENCE characterizes the height of a mountain or hill's summit by the vertical distance between it and the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit . A peak's _key col_ is a unique point on this contour line and the PARENT PEAK is some higher mountain, selected according to various objective criteria.

List Of Mountain Lists
There are many notable MOUNTAIN LISTS around the world. Typically, a list of mountains becomes notable by first being listed or defined by an author or group (e.g. Sir Hugh Munro defining the Munros in Scotland ). This list then becomes a popular target for peak bagging , where a number of people attempt to climb all of the peaks in the list. Alternatively, a list of mountains may become notable in the mountaineering community as a challenge. An example of such a challenge list is the Seven Summits defined by Richard Bass . Examples of notable lists of mountains are shown below. CONTENTS * 1 Worldwide * 2 Europe * 3 British Isles * 4 North America * 4.1 Canada * 4.2 Mexico * 4.3 United States * 5 Central America * 5.1 Guatemala * 6 South America * 7 Asia * 7.1 China * 7.2 Japan * 7.3 Indonesia * 7.4 Taiwan * 8 Australia * 9 See also * 10 References WORLDWIDE * The Eight-thousanders are the fourteen mountains over 8,000 metres (26,247 ft) in height, all in the Himalaya and Karakoram ranges in Asia . * The Seven Summits are the highest peaks on each continent , from the Vinson Massif in Antarctica to Everest in Asia . * The Seven Second Summits are the second highest peaks on each continent

List Of Highest Points In California By County
This is a list of highest points in the U.S. state of California , in alphabetical order by county. All elevations use the North American Vertical Datum of 1988 (NAVD88), the currently accepted vertical control datum for United States, Canada and Mexico. Elevations are from the National Geodetic Survey (NGS) when available. Others are from the United States Geological Survey topographic maps when available. These can be found on the Peakbagger.com web pages. Elevations followed by a plus sign (+) were interpolated by the compiler using topographic map contour lines . The true elevation is between that shown and the elevation plus the contour line interval which is forty feet in most instances. Elevations from the NGS are rounded to the nearest whole number

Geographic Coordinate System
A GEOGRAPHIC COORDINATE SYSTEM is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position , and two or three of the numbers represent a horizontal position . A common choice of coordinates is latitude , longitude and elevation . To specify a location on a two-dimensional map requires a map projection

Mountain Range
A MOUNTAIN RANGE also called MOUNTAINS or MOUNTAIN BARRIER/BELT/SYSTEM, is a geographic area containing numerous geologically related mountains . A mountain system or system of mountain ranges, sometimes is used to combine several geological features that are geographically (regionally) related. On Earth, most significant mountain ranges are the result of plate tectonics , though mountain ranges are formed by a range of processes, are 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 highlands or mountain passes and valleys . Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology . They may be a mix of different orogenic expressions and terranes , for example thrust sheets , uplifted blocks , fold mountains, and volcanic landforms resulting in a variety of rock types .

Topographic Map
In modern mapping, a TOPOGRAPHIC MAP is a type of map characterized by large-scale detail and quantitative representation of relief , usually using contour lines , but historically using a variety of methods . Traditional definitions require a topographic map to show both natural and man-made features. A topographic map is typically published as a map series , made up of two or more map sheets that combine to form the whole map. A contour line is a line connecting places of equal elevation. Natural Resources Canada provides this description of topographic maps: These maps depict in detail ground relief (landforms and terrain), drainage (lakes and rivers), forest cover, administrative areas, populated areas, transportation routes and facilities (including roads and railways), and other man-made features. Other authors define topographic maps by contrasting them with another type of map; they are distinguished from smaller-scale "chorographic maps" that cover large regions, "planimetric maps" that do not show elevations, and "thematic maps " that focus on specific topics. However, in the vernacular and day to day world, the representation of relief (contours) is popularly held to define the genre, such that even small-scale maps showing relief are commonly (and erroneously, in the technical sense) called "topographic"

Geologic Time Scale
The GEOLOGIC TIME SCALE (GTS) is a system of chronological dating that relates geological strata (stratigraphy ) to time, and is used by geologists , paleontologists , and other Earth scientists to describe the timing and relationships of events that have occurred during Earth\'s history . The table of geologic time spans, presented here, agrees with the nomenclature , dates and standard color codes set forth by the International Commission on Stratigraphy . Evidence from radiometric dating indicates that Earth is about 4.54 billion years old . The geology or _deep time _ of Earth's past has been organized into various units according to events which took place in each period. Different spans of time on the GTS are usually marked by changes in the composition of strata which correspond to those, and indicate major geological or paleontological events, such as mass extinctions . For example, the boundary between the Cretaceous period and the Paleogene period is defined by the Cretaceous–Paleogene extinction event , which marked the demise of the non-avian dinosaurs and many other groups of life. Older time spans, which predate the reliable fossil record (before the Proterozoic eon ), are defined by their absolute age

Cretaceous
The CRETACEOUS ( /krᵻˈteɪʃəs/ , _krə-TAY-shəs_ ) is a geologic period and system that spans 79 million years from the end of the Jurassic Period 145 million years ago (mya ) to the beginning of the Paleogene Period 66 mya. It is the last period of the Mesozoic Era . The Cretaceous Period is usually abbreviated K, for its German translation _Kreide_ (chalk). The Cretaceous was a period with a relatively warm climate , resulting in high eustatic sea levels that created numerous shallow inland seas . These oceans and seas were populated with now-extinct marine reptiles , ammonites and rudists , while dinosaurs continued to dominate on land. During this time, new groups of mammals and birds , as well as flowering plants , appeared. The Cretaceous ended with a large mass extinction , the Cretaceous– Paleogene extinction event , in which many groups, including non-avian dinosaurs, pterosaurs and large marine reptiles died out. The end of the Cretaceous is defined by the abrupt Cretaceous– Paleogene boundary (K–Pg boundary), a geologic signature associated with the mass extinction which lies between the Mesozoic and Cenozoic eras

Jurassic
The JURASSIC ( /dʒuːˈræsɪk/ ; from Jura Mountains ) was a geologic period and system that spanned for 56 million years from the end of the Triassic Period 201.3 million years ago (Mya ) to the beginning of the Cretaceous Period 145 Mya. The Jurassic constituted the middle period of the Mesozoic Era , also known as the Age of Reptiles. The start of the period was marked by the major Triassic–Jurassic extinction event . Two other extinction events occurred during the period: the Pliensbachian/ Toarcian event in the Early Jurassic, and the Tithonian event at the end; however, neither event ranks among the "Big Five" mass extinctions. The Jurassic is named after the Jura Mountains within the European Alps , where limestone strata from the period were first identified. By the beginning of the Jurassic, the supercontinent
