Course Of San Juan Creek
San Juan Creek is a creek in Orange County in the U.S. state of California. It is about long, and along with its major tributary, Trabuco Creek, drains near the southernmost extent of Orange County. This article describes the course of San Juan Creek. Headwaters to San Juan Canyon San Juan Creek begins in the southern Santa Ana Mountains, a few miles northwest of Lake Elsinore. Its highest elevation is above sea level. Paralleling the Ortega Highway (California State Route 74) the creek flows erratically south, west and occasionally northwest. In the furthest upper reaches of the watershed, the creek is typically ephemeral. The creek channel in the uppermost few miles is a narrow mountain stream with many rapids and waterfalls, which include a series of large cascades, known as San Juan Falls. There are little alluvial deposits in the canyons, and the creek mostly cascades over bedrock. In this upper reach, the pool-and-riffle stream channel structure is evident. There are a fe ...

Interstate 5
Interstate 5 (I-5) is the main north–south Interstate Highway on the West Coast of the United States, running largely parallel to the Pacific coast of the contiguous U.S. from Mexico to Canada. It travels through the states of California, Oregon, and Washington, serving several large cities on the U.S. West Coast, including San Diego, Los Angeles, Sacramento, Portland, and Seattle. It is the only continuous Interstate highway to touch both the Mexican and the Canadian borders. Upon crossing the Mexican border at its southern terminus, I-5 continues to Tijuana, Baja California, as Mexico Federal Highway 1 (Fed. 1). Upon crossing the Canadian border at its northern terminus, it continues to Vancouver as British Columbia Highway 99 (BC 99). I-5 was originally created in 1956 as part of the Interstate Highway System, but it was predated by several auto trails and highways built in the early 20th century. The Pacific Highway auto trail was built ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cleveland National Forest
Cleveland National Forest encompasses 460,000 acres (), mostly of chaparral, with a few riparian areas. A warm dry mediterranean climate prevails over the forest. It is the southernmost U.S. National Forest of California. It is administered by the U.S. Forest Service, a government agency within the United States Department of Agriculture. It is divided into the Descanso, Palomar and Trabuco Ranger Districts and is located in the counties of San Diego, Riverside, and Orange. History The Kumeyaay, Payómkawichum, Cahuilla, and Cupeño long inhabited various areas of the forest. They lived on various forms of food, including acorns and local wildlife. Many of the Cleveland National Forest's trails are built following the routes developed by these Indigenous peoples. Cleveland National Forest was created on July 1, 1908 with the consolidation of Trabuco Canyon National Reserve and San Jacinto National Reserve by President Theodore Roosevelt and named after former president Grov ...

Gabion
A gabion (from Italian ''gabbione'' meaning "big cage"; from Italian ''gabbia'' and Latin ''cavea'' meaning "cage") is a cage, cylinder or box filled with rocks, concrete, or sometimes sand and soil for use in civil engineering, road building, military applications and landscaping. For erosion control, caged riprap is used. For dams or in foundation construction, cylindrical metal structures are used. In a military context, earth- or sand-filled gabions are used to protect sappers, infantry, and artillerymen from enemy fire. Leonardo da Vinci designed a type of gabion called a ''Corbeille Leonard'' ("Leonard basket") for the foundations of the San Marco Castle in Milan. Civil engineering The most common civil engineering use of gabions was refined and patented by Gaetano Maccaferri in the late 19th century in Sacerno, Emilia Romagna and used to stabilize shorelines, stream banks or slopes against erosion. Other uses include retaining walls, noise barriers, temporary flood w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Culvert
A culvert is a structure that channels water past an obstacle or to a subterranean waterway. Typically embedded so as to be surrounded by soil, a culvert may be made from a pipe, reinforced concrete or other material. In the United Kingdom, the word can also be used for a longer artificially buried watercourse. Culverts are commonly used both as cross-drains to relieve drainage of ditches at the roadside, and to pass water under a road at natural drainage and stream crossings. When they are found beneath roads, they are frequently empty. A culvert may also be a bridge-like structure designed to allow vehicle or pedestrian traffic to cross over the waterway while allowing adequate passage for the water. Culverts come in many sizes and shapes including round, elliptical, flat-bottomed, open-bottomed, pear-shaped, and box-like constructions. The culvert type and shape selection is based on a number of factors including requirements for hydraulic performance, limitations on up ...

San Juan Capistrano
San Juan Capistrano (Spanish for "St. John of Capistrano") is a city in Orange County, California, located along the Orange Coast. The population was 34,593 at the 2010 census. San Juan Capistrano was founded by the Spanish in 1776, when St. Junípero Serra established Mission San Juan Capistrano. Extensive damage caused by the 1812 Capistrano earthquake caused the community to decline. Following the Mexican secularization act of 1833, the mission village officially became a town and was briefly renamed as San Juan de Argüello. Following the American Conquest of California, San Juan remained a small, rural town until the 20th century; the restoration of the mission in the 1910–20s transformed the town into a tourist destination and a backdrop for Hollywood films. History Indigenous The region was populated by the Acjachemen, referred to by the Spanish as ''Juaneños'', an Indigenous Californian nation. They lived in the area for approximately 10,000 years, with some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
