Iron Horse Trail Ygnacio Valley Rd Bridge 01
Iron () is a chemical element with symbol Fe (from la, ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or furnaces capable of reaching or higher, about higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BCE and the use of iron tools and weapons began to displace copper alloys, in some regions, only around 1200 BCE. That event is considered the transition from the Bronze Age to the I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arterial Road
An arterial road or arterial thoroughfare is a high-capacity urban road that sits below freeways/motorways on the road hierarchy in terms of traffic flow and speed. The primary function of an arterial road is to deliver traffic from collector roads to freeways or expressways, and between urban centres at the highest level of service possible. As such, many arteries are limited-access roads, or feature restrictions on private access. Because of their relatively high accessibility, many major roads face large amounts of land use and urban development, making them significant urban places. In traffic engineering hierarchy, an arterial road delivers traffic between collector roads and freeways. For new arterial roads, intersections are often reduced to increase traffic flow. In California, arterial roads are usually spaced every half mile, and have intersecting collector(s) and streets. Some arterial roads, characterized by a small fraction of intersections and driveways compared to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interstate 680 (California)
Interstate 680 (I-680) is a north–south auxiliary Interstate Highway in Northern California. It curves around the eastern cities of the San Francisco Bay Area from San Jose to I-80 at Fairfield, bypassing cities along the eastern shore of San Francisco Bay such as Oakland and Richmond while serving others more inland such as Pleasanton and Concord. Built in the 1920s and designated in 1955, I-680 begins at a junction with I-280 and US Route 101 (US 101/ Bayshore Freeway) and heads northeast and north-northwest through the northeast part of San Jose. After passing State Route 237 (SR 237) in Milpitas and SR 262 in Fremont, I-680 abruptly turns northeast (where a connection to a SR 238 freeway was planned) and enters the hills and valleys of the California Coast Ranges. The highway crosses over Mission Pass, also known as the Sunol Grade, and descends into the Sunol Valley, where it meets SR 84 near Sunol. From Sunol, I-680 agai ...

Clayton, California
Clayton (formerly Clayton's and Claytonville) is a city in Contra Costa County, California, United States. The population was 10,897 as of the 2010 census. History In 1857, the town of Clayton was laid out and founded by Joel Henry Clayton (1812–1872) and his two younger brothers. Clayton was born in Bugsworth, now Buxworth, in the United Kingdom, and emigrated to the United States in 1837. After years in other states he settled down with his wife Margaret (1820–1908) at his town at the foot of Mount Diablo, where he and his family prospered. Clayton was named after Joel Henry Clayton, although only by the flip of a coin. Joel Clayton and Charles Rhine cofounded the town, and each wanted to name it after himself. If Charles had won it would have become Rhinesville, but Joel Clayton won. Joel and his wife Margaret both died in Clayton, and were buried in Live Oak Cemetery in what is now Concord, CA. Clayton prospered during the coal mining boom in eastern Contra Costa County ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diablo Range
The Diablo Range is a mountain range in the California Coast Ranges subdivision of the Pacific Coast Ranges in northern California, United States. It stretches from the eastern San Francisco Bay area at its northern end to the Salinas Valley area at its southern end. Geography The Diablo Range extends from the Carquinez Strait in the north to Orchard Peak and Polonio Pass in the south, near the point where State Route 46 crosses over the Coast Ranges at Cholame, as described by the United States Geological Survey (USGS). It is bordered on the northeast by the San Joaquin River, on the southeast by the San Joaquin Valley, on the southwest by the Salinas River, and on the northwest by the Santa Clara Valley. The USGS designation is somewhat ambiguous north of the Santa Clara Valley, but on USGS maps, the range is shown as the ridgeline which runs between its namesake Mount Diablo southeastward past Mount Hamilton. Geologically, the range corresponds to the California Coast R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
