San Geronimo Creek
San Geronimo Creek is a stream in Marin County, California, United States, which feeds into Lagunitas Creek below Kent Lake. Course The creek rises in the hills west of the town of Fairfax. It descends northward to Woodacre, where it turns westward and parallels Sir Francis Drake Boulevard through the villages of San Geronimo, Forest Knolls, and Lagunitas. It then turns southwestward and joins Lagunitas Creek at the eastern edge of the Samuel P. Taylor State Park. Ecology The 6000 acre San Geronimo Creek watershed is within the 60,000 acre Lagunitas Creek Watershed, which is home to the largest-remaining wild run of coho salmon in central California. These coho are part of the "Central California Coast Evolutionarily Significant Unit," or CCC ESU, and are listed as "endangered" at both the state and federal level. Efforts are also being made to protect and restore streams and habitat in the San Geronimo Valley, where upwards of 20% of the Lagunitas salmon spawn each year ...

Fairfax, California
Fairfax is an incorporated town in Marin County, California, United States. Fairfax is located west-northwest of San Rafael, at an elevation of . The population was 7,605 at the 2020 census. History The Coast Miwok Native Americans occupied stretches along local creeks, spring and seep areas; moreover, prehistoric habitations were usually chosen near permanent and seasonal drainages, typically along flat ridges and terraces. The town was named for Lord Charles Snowden Fairfax. In 1861, Fairfax was the site of the last political duel in California. Daniel Showalter and Charles W. Piercy, both former assemblymen in the state legislature, decided to settle a political dispute at the home of Lord Fairfax, a mutual friend. Although Fairfax provided lunch to both men and tried to talk them out of it, they eventually headed to an open field nearby and dueled, with Showalter killing Piercy. The first post office opened in 1910. Fairfax became an incorporated town in 1931. On May ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rivers Of Marin 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 ...

California State Route 1
State Route 1 (SR 1) is a major north–south state highway that runs along most of the Pacific coastline of the U.S. state of California. At , it is the longest state route in California, and the second-longest in the US after Montana Highway 200. SR 1 has several portions designated as either Pacific Coast Highway (PCH), Cabrillo Highway, Shoreline Highway, or Coast Highway. Its southern terminus is at Interstate 5 (I-5) near Dana Point in Orange County and its northern terminus is at U.S. Route 101 (US 101) near Leggett in Mendocino County. SR 1 also at times runs concurrently with US 101, most notably through a stretch in Ventura and Santa Barbara counties, and across the Golden Gate Bridge. The highway is designated as an All-American Road. In addition to providing a scenic route to numerous attractions along the coast, the route also serves as a major thoroughfare in the Greater Los Angeles Area, the San Francisco Bay Area, and several ...

Tee Beam
A T-beam (or tee beam), used in construction, is a load-bearing structure of reinforced concrete, wood or metal, with a -shaped cross section. The top of the -shaped cross section serves as a flange or compression member in resisting compressive stresses. The web (vertical section) of the beam below the compression flange serves to resist shear stress. When used for highway bridges the beam incorporates reinforcing bars in the bottom of the beam to resist the tensile stresses which occur during bending. The T-beam has a big disadvantage compared to an I-beam (with shape) because it has no bottom flange with which to deal with tensile forces. One way to make a T-beam more efficient structurally is to use an inverted T-beam with a floor slab or bridge deck joining the tops of the beams. Done properly, the slab acts as the compression flange. History A T-beam is a structural element able to withstand large loads by resistance in the beam or by internal reinforcements. In some r ...

Prestressed Concrete
Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" ( compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. Post-tensioned concreted is "structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in the concrete resulting from loads." This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service. Tendons may consist of single wires, multi-wire strands or threaded bars that are most commonly made from high-tensile steels, carbon fiber or aramid fiber. The essence of prestressed concrete is that once the initial compression has been applied, the resulting material has the characteristics of high-strength concrete when subject to any subsequent compression forces and of ductile high-strength steel when sub ...

San Geronimo Valley
San Geronimo Valley is located in Marin County, California, composed of four unincorporated towns: Woodacre, San Geronimo, Forest Knolls, and Lagunitas. It is a fairly close-knit community, with a rather liberal citizenry. The farther west one goes along the valley, the more forested the land becomes. The valley is bisected roughly east-to-west by Sir Francis Drake Boulevard; a number of streets in the towns along this road were constructed on the former right-of-way of the Northwestern Pacific Railroad. The valley has numerous hiking/biking trails. Most of the residents reside on the south, shadier, side of the valley. The San Geronimo Valley derives its name from the San Geronimo Ranch, established by Adolph Mailliard and Ann Eliza Ward in 1868, where they bred thoroughbred horses, including the famous stallion Monday, who sired most of the race horses in California. The Valley is part of the Lagunitas School District, unique in that it operates two alternative elemen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coho Salmon
The coho salmon (''Oncorhynchus kisutch;'' Karuk: achvuun) is a species of anadromous fish in the salmon family and one of the five Pacific salmon species. Coho salmon are also known as silver salmon or "silvers". The scientific species name is based on the Russian common name ''kizhuch'' (кижуч). Description During their ocean phase, coho salmon have silver sides and dark-blue backs. During their spawning phase, their jaws and teeth become hooked. After entering fresh water, they develop bright-red sides, bluish-green heads and backs, dark bellies and dark spots on their backs. Sexually maturing fish develop a light-pink or rose shading along the belly, and the males may show a slight arching of the back. Mature adults have a pronounced red skin color with darker backs and average and , occasionally reaching up to . They also develop a large kype (hooked beak) during spawning. Mature females may be darker than males, with both showing a pronounced hook on the nose. Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sir Francis Drake Boulevard
Sir Francis Drake Boulevard is an approximately 43.8 mile east–west arterial road in Marin County, California, running from the trailhead for Point Reyes Lighthouse at the end of the Point Reyes Peninsula to Interstate 580 just west of the Richmond-San Rafael Bridge. It is a main thoroughfare through (from west to east) the communities of Inverness, Point Reyes Station, Olema, Lagunitas-Forest Knolls, San Geronimo, Woodacre, Fairfax, San Anselmo, Ross, Kentfield, Greenbrae, and Larkspur. The road overlaps State Route 1 between Point Reyes Station and Olema. It is named for the English privateer, explorer and world circumnavigator Francis Drake, whose ship ''The Golden Hind'' landed somewhere along the Pacific coast of North America in 1579, claiming the area for England as "Nova Albion." Drake's landing place has often been theorized to be at what is now called Drakes Bay Drakes Bay (Coast Miwok: ''Tamál-Húye'') is a wide bay named so by U.S. surveyor Georg ...
