Morro Creek
Morro Creek is a coastal stream in San Luis Obispo County, in the central region of the U.S. state of California. The watercourse flows from the Santa Lucia Mountains to discharge into the Pacific Ocean, at its mouth on Estero Bay, near the city of Morro Bay. Natural history The creek is in the coastal sage and chaparral section of the California chaparral and woodlands Ecoregion. Historically this watershed had habitats containing considerable amounts of chaparral, and scarce Oak woodlands, and Grey Pine (''Pinus sabiniana'') trees. Cultural history The lower reaches of Morro Creek were used as a significant settlement of the Chumash tribe since at least the Millingstone Horizon. There is also incidence of historic mining of chromium within the catchment basin.USGS, 1910 It was used extensively for grazing by the cattle ranches.

Stream
A stream is a continuous body of surface water flowing within the bed and banks of a channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long large streams are usually called rivers, while smaller, less voluminous and more intermittent streams are known as streamlets, brooks or creeks. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighted subterranean water, and surfaced groundwater ( spring water). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes that respond to geological, geomorphological, hydrological and biotic controls. Streams are important as conduits in the water cycle, instruments in groundw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinus Sabiniana
''Pinus sabiniana'' (sometimes spelled ''P. sabineana''), with vernacular names including towani pine, foothill pine, gray pine, bull pine, and digger pine, is a pine endemic to California in the United States. Some sources discourage using the name "digger pine," considering it pejorative ("digger" was a slur commonly used to refer to Indigenous Americans in the Great Basin and California). Description The ''Pinus sabiniana'' tree typically grows to , but can reach feet in height. The needles of the pine are in fascicles (bundles) of three, distinctively pale gray-green, sparse and drooping, and grow to in length. The seed cones are large and heavy, in length and almost as wide as they are long. When fresh, they weigh from , rarely over . The male cones grow at the base of shoots on the lower branches.

Rivers Of San Luis Obispo County, California
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, a ...

Morro Rock
Morro Rock (Salinan: ''Le'samo; ''Chumash: ''Lisamu'''; Spanish: ''El Morro'') is a volcanic plug in Morro Bay, California, on the Pacific Coast at the entrance to Morro Bay harbor. A causeway connects it with the shore, making it a tied island. The rock is protected as the Morro Rock State Preserve. Geology The Morro Rock is one of 13 volcanic plugs (remnant necks of extinct volcanoes), lava domes, and sheetlike intrusions between Morro Bay on the north and Islay Hill on the south, all in San Luis Obispo County. It is composed mostly of dacite, an igneous, volcanic rock, and partially of petrified bird feces, which have compacted into the plug over the years. It is a groundmass of plagioclase, with amphibole (hornblende), biotite, pyroxene (augite), quartz, and glass; phenocrysts of plagioclase. Its silica dioxide (SiO2) content can range from 63 to 69 percent. The dacite volcanic plugs, lava domes, intrusive sheets, and felsitic rhyolite-dacite between Morro ...

Morro Bay State Park Museum Of Natural History
The Morro Bay State Park Museum of Natural History is a natural history museum in Morro Bay State Park, Morro Bay, California, United States, opened in 1962. The museum sits on a hill overlooking the Morro Bay estuary, midway between Los Angeles and San Francisco, with a view of Morro Rock. It is the only natural history museum in the California State Park system. From 1993 through 2002, the museum was remodeled in a three phase modernization project, with exhibits by Exhibitgroup Giltspur, which has also created exhibits for the Smithsonian and J. Paul Getty museums.

Millingstone Horizon
Millingstone Horizon is an archaeological period of Native American dominance denoting a period in California, United States involving extensive use of manos and other grinding technology. The interval is a subset of the Archaic Period; specifically Millingstone is usually applied to the period 6500 to 1500 BC. Alternatively this epoch within North America is known as the Encinitas Tradition. Archaeological recovery from a number of sites in California has yielded evidence of Native American habitation and daily life in this period that ended around 3,500 years ago. Example sites The Chumash people, who inhabited much of present-day San Luis Obispo County, Santa Barbara County, and Ventura County have Millingstone Horizon elements in their history. For example, an extensive site at Morro Creek in the present day town of Morro Bay has yielded evidence of coastal Chumash in the Millingstone period.C.M.

Chumash People
The Chumash are a Native American people of the central and southern coastal regions of California, in portions of what is now San Luis Obispo, Santa Barbara, Ventura and Los Angeles counties, extending from Morro Bay in the north to Malibu in the south. Their territory included three of the Channel Islands: Santa Cruz, Santa Rosa, and San Miguel; the smaller island of Anacapa was likely inhabited seasonally due to the lack of a consistent water source. Modern place names with Chumash origins include Malibu, Nipomo, Lompoc, Ojai, Pismo Beach, Point Mugu, Port Hueneme, Piru, Lake Castaic, Saticoy, Simi Valley and Somis. Archaeological research demonstrates that the Chumash people have deep roots in the Santa Barbara Channel area and lived along the southern California coast for millennia. History Prior to European contact (pre-1542) Indigenous peoples have lived along the California coast for at least 11,000 years. Sites of the Millingstone Horizon date fro ...

California Oak Woodland
California oak woodland is a plant community found throughout the California chaparral and woodlands ecoregion of California in the United States and northwestern Baja California in Mexico. Oak woodland is widespread at lower elevations in coastal California; in interior valleys of the Coast Ranges, Transverse Ranges and Peninsular Ranges; and in a ring around the California Central Valley grasslands. The dominant trees are oaks, interspersed with other broadleaf and coniferous trees, with an understory of grasses, herbs, geophytes, and California native plants. Oak savannas occur where the oaks are more widely spaced due a combination of lack of available moisture, and low-intensity frequent fires. The oak woodlands of Southern California and coastal Northern California are dominated by coast live oak ('' Quercus agrifolia''), but also include valley oak ( ''Q. lobata''), California black oak ( ''Q. kelloggii''), canyon live oak ( ''Q. chrysolepis''), and other California oaks. ...
