Aliso Canyon
Aliso Canyon is a canyon located in Orange County, California in the United States. The canyon is a water gap across the San Joaquin Hills carved out by Aliso Creek, possibly as recently as the last ice age. Located in a semi-arid climate, it supports a variety of plant communities – mainly chaparral and coastal sage scrub – and native animals, some endangered. The canyon's northern divide once formed a formidable boundary between the indigenous Acjachemen and Tongva. Many Acjachemen archaeological sites have been found in the canyon. The fertile alluvial soil and grasslands of Aliso Canyon was used for orchards and grazing from Spanish conquest of the region until the early 20th century. Since the 1970s, the canyon has been the centerpiece of Aliso and Wood Canyons Wilderness Park. Aliso Canyon has also suffered environmental damage in recent years. Upstream urban development since the 1950s has increased urban runoff into Aliso Creek, causing severe erosion throughou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aliso Creek (Orange County)
Aliso Creek is a -long, mostly urban stream in south Orange County, California. Originating in the Cleveland National Forest in the Santa Ana Mountains, it flows generally southwest and empties into the Pacific Ocean at Laguna Beach. The creek's watershed drains , and it is joined by seven main tributaries. As of 2018, the watershed had a population of 144,000 divided among seven incorporated cities. Aliso Creek flows over highly erosive marine sedimentary rock of late Eocene to Pliocene age. What would become the Aliso Creek watershed originally lay at the bottom of the Pacific Ocean, before being uplifted as recently as 10 million years ago. About 1.2 million years ago, the San Joaquin Hills began to uplift in the path of Aliso Creek. Occasionally swollen by wetter climates during glacial periods, the creek carved the deep water gap known today as Aliso Canyon, the main feature of Aliso and Wood Canyons Wilderness Park. Historically, Aliso Creek served as the bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wisconsinian Glaciation
The Wisconsin glaciation, also called the Wisconsin glacial episode, was the most recent glacial period of the North American ice sheet complex, peaking more than 20,000 years ago. This advance included the Cordilleran Ice Sheet, which nucleated in the northern North American Cordillera; the Innuitian ice sheet, which extended across the Canadian Arctic Archipelago; the Greenland ice sheet; and the massive Laurentide Ice Sheet, which covered the high latitudes of central and eastern North America. This advance was synchronous with global glaciation during the last glacial period, including the North American alpine glacier advance, known as the Pinedale glaciation. The Wisconsin glaciation extended from about 75,000 to 11,000 years ago, between the Sangamonian Stage and the current interglacial, the Holocene. The maximum ice extent occurred about 25,000–21,000 years ago during the last glacial maximum, also known as the ''Late Wisconsin'' in North America. This glaciation ...

Laguna Niguel, California
Laguna Niguel () is a city in Orange County, California, United States.

Sewage Treatment
Sewage treatment is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges. Sewage contains wastewater from households and businesses and possibly pre-treated Industrial wastewater treatment, industrial wastewater. There are a large number of sewage treatment processes to choose from. These can range from Decentralized wastewater system, decentralized systems (including on-site treatment systems) to large centralized systems involving a network of pipes and pump stations (called sewerage) which convey the sewage to a treatment plant. For cities that have a combined sewer, the sewers will also carry urban runoff (stormwater) to the sewage treatment plant. Sewage treatment often involves two main stages, called primary and secondary treatment, while advanced treatment also incorpo ...

Wood Canyon Creek
Wood Canyon Creek is a perennial stream in Aliso and Wood Canyons Wilderness Park, Orange County, California, Orange County, California. A tributary of Aliso Creek (Orange County), Aliso Creek, it drains a deep undeveloped valley to the west of Aliso Viejo, California, Aliso Viejo. The Wood Canyon was populated by the Acjachemen tribe hundreds of years ago; many archaeological sites along the creek provide evidence of their habitation. Spanish explorers and colonists arrived in the mid-18th century, establishing missions and a Ranchos of California, rancho that extended around the Aliso Creek watershed. Wood Canyon was used first as a cattle grazing area; after California became part of the United States, it was used to graze sheep. From the 1960s onward, the creek's flow has been heavily affected by urban runoff from suburban residential development. The Wood Canyon watershed drains a portion of the San Joaquin Hills, a short coastal mountain range that uplifted beginning in the ...

Laguna Canyon
Laguna Canyon, also called , is a gorge that cuts through the San Joaquin Hills in southern Orange County, California, in the United States, directly south of the city of Irvine. The canyon runs from northeast to southwest, and is drained on the north side by tributaries of San Diego Creek and on the south by Laguna Canyon Creek. It is deeper and more rugged on the southwestern end near Laguna Beach. Geologically, the canyon likely originated millions of years ago as the result of San Diego Creek cutting through the San Joaquin Hills. Uplift diverted that stream to its present course, leaving Laguna Canyon as a wind gap. California State Route 133 runs the entire length of the canyon connecting Laguna Beach and Irvine, while California State Route 73 crosses it, running southeast–northwest. A majority of the canyon is located within the Laguna Coast Wilderness Park; small portions are part of Aliso and Wood Canyons Wilderness Park and the cities of Irvine, Laguna Beach, Lag ...
