Sierra Nevada
The Sierra Nevada () is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, an almost continuous chain of mountain ranges that forms the western "backbone" of the Americas. The Sierra runs north-south and its width ranges from to across east–west. Notable features include General Sherman, the largest tree in the world by volume; Lake Tahoe, the largest alpine lake in North America; Mount Whitney at , the highest point in the contiguous United States; and Yosemite Valley sculpted by glaciers from one-hundred-million-year-old granite, containing high waterfalls. The Sierra is home to three national parks, twenty wilderness areas, and two national monuments. These areas include Yosemite, Sequoia, and Kings Canyon National Parks; and D ...

Mountain Pass
A mountain pass is a navigable route through a mountain range or over a ridge. Since many of the world's mountain ranges have presented formidable barriers to travel, passes have played a key role in trade, war, and both human and animal migration throughout history. At lower elevations it may be called a hill pass. A mountain pass is typically formed between two volcanic peaks or created by erosion from water or wind. Overview Mountain passes make use of a gap, saddle, col or notch. A topographic saddle is analogous to the mathematical concept of a saddle surface, with a saddle point marking the highest point between two valleys and the lowest point along a ridge. On a topographic map, passes are characterized by contour lines with an hourglass shape, which indicates a low spot between two higher points. In the high mountains, a difference of between the summit and the mountain is defined as a mountain pass. Passes are often found just above the source of a river ...

Ebbetts Pass
Ebbetts Pass (el. ), named after John Ebbetts, is a high mountain pass through the Sierra Nevada range in Alpine County, California. Ebbetts is the eastern of two passes in the area traversed by State Route 4. The western pass is the Pacific Grade Summit (el ). The pass is registered as a California Historical Landmark. The Pacific Crest Trail, a long National Scenic Trail crosses State Route 4 at Ebbetts Pass. History Native Americans were undoubtedly the first humans to traverse the Sierra Nevada Mountains, but it is unknown if they regularly used Ebbetts Pass since any trail they would have used is no longer traceable. It is traditionally held to be the pass used by Jedediah Smith in late spring of 1827 when leaving California at the end of his first exploratory journey, the first crossing ever of the Sierra Nevada by a non-native, but snow would have obscured any trail so he was blazing his own path. It may also have been used by the Bartleson–Bidwell Party on their emigr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

California State Route 4
State Route 4 (SR 4) is a state highway in the U.S. state of California, routed from Interstate 80 in the San Francisco Bay Area to State Route 89 in the Sierra Nevada. It roughly parallels the Sacramento-San Joaquin River Delta, a popular area for boating and fishing, with a number of accesses to marinas and other attractions. After crossing the Central Valley, the highway ascends up the Sierra foothills. It passes through Ebbetts Pass and contains the Ebbetts Pass Scenic Byway, a National Scenic Byway. Route description SR 4, an east–west highway, begins in Hercules at San Pablo Avenue next to the Interstate 80 junction as part of John Muir Parkway. (The actual parkway extends a bit past the western terminus.) The road is an expressway from its starting point until it approaches Martinez, at which point it becomes a full freeway (the California Delta Highway) passing Concord, Pittsburg, and Antioch. The John Muir National Historic Site is located directly nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
State Scenic Highway System (California)
The State Scenic Highway System in the U.S. state of California is a list of highways, mainly state highways, that have been designated by the California Department of Transportation (Caltrans) as scenic highways. They are marked by the state flower, a California poppy, inside either a rectangle for state-maintained highways or a pentagon for county highways. The California State Legislature makes state highways eligible for designation as a scenic highway, listing them in the Streets and Highways Code, sections 260-284. For a highway to then be declared scenic by Caltrans, the local government with jurisdiction over abutting land must adopt a "scenic corridor protection program" that limits development, outdoor advertising, and earthmoving, and Caltrans must agree that it meets the criteria. The desire to create such a designation has at times been in conflict with the property rights of abutters, for example on State Route 174. Any county highway that is believed to have ou ...

Mountain Passes Of The Sierra Nevada (United States)
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 ...
