53-568: The name Tamalpais was first recorded in 1845. It comes from the Coast Miwok name for this mountain, támal pájiṣ , meaning "west hill". Various different folk etymologies also exist, but they are unsubstantiated. One holds that it comes from the Spanish Tamal país , meaning "Tamal country," Tamal being the name that the Spanish missionaries gave to the Coast Miwok people. Another holds that

106-512: A 170-acre (0.69 km ) parcel 1/2 mile upstream from the lagoon, and constructed levees along the right banks in 1948–1949 to prevent overbank flooding. These historical actions created an artificially-straight, constrained stream with relatively little habitat heterogeneity, nicknamed the "Bowling Alley" reach. The NPS acquired this property in 1980, with an agreement allowing the Banduccis to continue farming until 1995. In 1945, George Wheelwright,

159-484: A blind thrust fault does exist under Mount Tamalpais, and if it ruptures, it could be potentially devastating to the North Bay, San Francisco, and any other nearby locale resting on unstable earth and loose fill. Major Mount Tamalpais rockforms include serpentine , particularly evident in outcroppings near the summit and on the north side. A number of serpentine endemic plants grow in the serpentine soils in this part of

212-613: A co-founder of Polaroid , purchased the Green Gulch Farm and Muir Beach where he created pasture by constructing drainage channels, levees, a dam and a large drainage channel along Redwood Creek. In 1967, Wheelwright donated the Muir Beach area to the California State Parks who built a large parking lot in the current location by the beach. In 1972, Wheelwright sold the Green Gulch Farm to Zentatsu Richard Baker who transformed

265-499: A distinctive DNA. The Redwood Creek salmon are Central California Coast coho salmon evolutionarily significant unit (ESU) which have been listed as federally threatened species since October 1996 and as federally endangered species in June 2005. Coho migrate from the ocean back to freshwater for a single chance at reproduction, generally after two years in the ocean. The spawning migrations begin after heavy late fall or winter rains breach

318-462: A few isolated areas, are of two types. Northern coastal prairie is found below the fog line and is characterized by a Festuca - Danthonia association, while valley grassland , found in drier areas, is dominated by Nassella pulchra , with Elymus glaucus and Leymus triticoides also being common. Wetland vegetation types found on Mount Tamalpais include coastal riparian forests, wet meadows , and some marsh areas. Coastal riparian forest

371-404: A functional, self-sustaining ecosystem and improve visitor access. The intervention was almost too late, since the coho only has a three-year life span. Fortunately, as of January, 2010 and for the first time in three years, an estimated 45 coho swam up Redwood Creek to spawn, creating 23 redds or clusters of eggs. In 2011, 11 live adult coho and 1 coho carcass was observed, along with three redds,

424-558: A modest increase over the 2007-2008 spawning season. Statewide the coho population is 1% of its levels in the 1940s and the fish have vanished from 90% of the streams they formally visited. The Watershed Alliance of Marin reported that no salmon returned to spawn in 2014, prompting concerns that the fish may now be locally extinct. Three adult male coho captured from the creek as juveniles in 2014 were released with three Olema Creek females as part of California Department of Fish and Wildlife operation "coho jumpstart", and at least one of

477-402: A new 650 foot meandering channel with three side-channels, in an attempt to restore the historic Big Lagoon , which according to 1850 maps, extended all the way back to the present Pelican Inn. Once the planted native vegetation takes hold on the new stream banks, the current parking lot will be rotated 90 degrees and the new channel connected. Other rare species living in the watershed include

530-525: A self-service fee ($ 8). The scenic Ridgecrest Blvd. running along the ridgeline between the Rock Spring trailhead and Fairfax-Bolinas Road, with panoramic views of the summit, Pacific, San Francisco , Bolinas , and Point Reyes , is featured in many automobile and other advertisements, as well as being the local hang-gliding launch point. Mount Tam is also home to the Edgewood Botanic Garden and to

583-508: Is a rare variety of thistle known only from the serpentine seeps of the mountain. The Mount Tamalpais jewelflower ( Streptanthus batrachopus ) is also limited to the area. Mount Tamalpais provides one of the last remaining wildlife refuges in the Bay Area. Urbanization has invaded wildlife habitat, forcing many fauna in southern Marin County to retreat up onto Mount Tamalpais, Muir Woods , and

636-403: Is formed by the confluence Rattlesnake Creek and Spike Buck Creeks at elevation 341 feet (104 m) on the southern flanks of Mount Tamalpais , however its tributaries begin on the peak at about 2,000 feet (610 m). Mainstem tributaries in descending order include Fern Creek, anadromous Kent Creek, and Green Gulch Creek. Prior to the land use changes that followed European colonization of

689-438: Is more dominant in shadier, moister areas; madrone is abundant in certain soil types in both moist and dry spots. Oak woodlands are a more open-canopy forest dominated by coast live oak, while oak savannah has a completely open canopy and represents a mixture of coast live oak woodland and grassland. The great diversity of microclimates on Mount Tamalpais ensures a wide variety of plant communities as well. Plant communities on

742-434: Is predominant along the valley streams of Mount Tamalpais. Red and white alder ( Alnus rubra and Alnus rhombifolia ) and arroyo and yellow willow ( Salix lasiolepis and S. lasiandra ) are dominant in these types of woodland, with bigleaf maple ( Acer macrophyllum ), box-elder ( Acer negundo ssp. californicum ), and California bay also being common. Wet meadows are present in several high-elevation spots on

795-526: The Bolinas Ridge . A wide variety of avifauna , amphibians , arthropods and mammals are found on Mount Tamalpais, including a number of rare and endangered species . Mt. Tamalpais and the neighboring Golden Gate Recreation Area together encompass over 115 square miles (298 square kilometers) of land, forming one of the largest preserved parklands located near a U.S. urban center. The Coast Miwok are said to have believed that an evil witch dwelled at

848-829: The Indigenous languages of the Americas is a stub . You can help Misplaced Pages by expanding it . Redwood Creek (Marin County) Redwood Creek is a mostly perennial stream in Marin County, California . 4.7 miles (7.6 km) long, it drains a 7-square-mile (18 km ) watershed which includes the Muir Woods National Monument , and reaches the Pacific Ocean north of the Golden Gate at Muir Beach . At

901-698: The Marin County Fire Department . Mount Tamalpais is a hiking, picnicking, mountain and road cycling, horseback riding, and hang-gliding destination for residents of the San Francisco Bay Area , with over 100 miles (160 km) of trails and fire roads. With numerous trailheads, a well-networked trail and road system, and hikes of greatly varying length and difficulty, the mountain offers a compelling range of attractions. Marin Municipal Water District maintains several reservoirs on

954-629: The Sidney B. Cushing Amphitheatre where Broadway musical productions are performed every year by the Mountain Play Association. Monthly astronomy viewings and lectures are held at Rock Spring and Mountain Theater April through October by Mt Tam Astronomy. Since the Mount Tamalpais area contains large expanses of undeveloped, natural land, there are many trails and trailheads that criss-cross

1007-757: The northern spotted owl ( Strix occidentalis caurina ) and the California red-legged frog ( Rana aurora draytonii ). In late 2009 the NPS excavated a pond in a pasture at Green Gulch Farm to provide habitat for the dwindling California red-legged frog population, the only one in the watershed. River otter ( Lontra canadensis ) were spotted in Redwood Creek in 1996, and return every year to eat steelhead trout. River otter were not listed as native to Marin County in Grinnell's 1937 Fur-bearing Mammals of California . Redwood Creek

1060-515: The Bolinas Ridge and the summit of Mount Tamalpais. In summer, the area gets almost no precipitation, except for fog drip that occurs in Muir Woods, the Bolinas Ridge and the western end of Mount Tamalpais, where summer fog and oceanic breezes are more prevalent. In contrast, the eastern foothills, sheltered from the oceanic breezes and fog, are drier, since the foothills force little moisture out of

1113-809: The Mount Tamalpais Watershed. It adjoins the Golden Gate National Recreation Area (which in turn adjoins Point Reyes National Seashore ) as well as several Marin County Open Space Preserves. This provides nearly 40 miles (64 km) of continuous publicly accessible open space. Some of the lower slopes of Mount Tamalpais fall within several cities and unincorporated communities of Marin County, including Mill Valley , Tamalpais-Homestead Valley , Stinson Beach , and Kentfield . These areas are generally developed, consisting of mostly low-density single-family homes . Like

1166-591: The West Peak, where a radar dome currently stands, is between 2,560 feet (780 m) and 2,578 feet (786 m) It stood over 2,600 feet (792 m) before the summit was flattened for the radar dome construction. The East Peak is at 2,571 feet (784 m). The mountain is clearly visible from parts of San Francisco and the East Bay . The majority of the mountain is contained in protected public lands, including Mount Tamalpais State Park, Muir Woods National Monument , and

1219-510: The air. This leads to the fact that the eastern slopes contain only oak, pine, chaparral shrub, coastal sage scrub , grassland and sparse Douglas-fir forest. Coastal sage scrub also occurs on some of the exposed coastal slopes. Temperatures on top of Mount Tamalpais are generally somewhat cooler than places next to the San Francisco Bay or the ocean due to elevation. In summer, however, the top of Mount Tamalpais may actually be warmer than

1272-509: The area. Many of these trails are used by hikers and bikers seeking refuge from the urban landscape of the San Francisco Bay Area. Some of these trails, including the mountaintop or ridgetop trails, have views of the San Francisco Bay and Pacific Ocean. Other trails, usually lower elevation valley trails, lead into natural, dense groves of mature Douglas-fir and redwood trees, clear, open grassland, and shrublands. All roads leading to

1325-469: The birthplace of mountain biking in the 1970s, where early mountain bikers such as Gary Fisher , Charlie Kelly , and Joe Breeze were active. British philosopher Alan Watts owned a cabin on Mount Tamalpais later in his life where he ultimately died in his sleep of heart failure on November 16, 1973. On top of the East Peak is a fire lookout station, staffed during the summer months by volunteers with

1378-402: The drier, eastern foothills to about 59 inches (1,500 mm) near the Bolinas Ridge , close to the Pacific Ocean . Both Mount Tamalpais and the Bolinas Ridge force moisture out of the air efficiently, since the air is cooled rapidly as it ascends the steep mountain faces and thus Mount Tamalpais's western part is heavily forested with tall redwoods and Douglas firs. The same fact holds for

1431-465: The fog line with relatively low overall rainfall or thin soils are often the site of a northern coastal scrub community characterized by coastal sage - coyote brush association, with lesser amounts of poison-oak , bush monkeyflower , California blackberry , western bracken fern , and various species of grasses and forbs . Chaparral is predominant in areas characterized by thin, rocky soils and little moisture. Two main types of chaparral are found

1484-645: The fog line, and deep soils. Muir Woods is the most extensive and best-known redwood forest of the Mount Tamalpais area. Mixed evergreen forests of various combinations of tanoak , madrone , coast and canyon live oak , and Douglas-fir are found in moist areas on middle to high elevations on the mountain. Very moist areas of mixed evergreen forest may also include bay, redwood, and California torreya . Areas in which mixed evergreen forests are predominant include areas of Fairfax-Bolinas Road and Ridgecrest Boulevard and around Alpine Lake . Various kinds of scrub communities are also widespread. Low-elevation areas below

1537-488: The instream project was to create rearing pools for juvenile salmonids. NPS also removed invasive, non-native vegetation in the riparian corridor, and replaced it with native vegetation to enhance nesting habitat for resident and migrant riparian songbirds. The current phase of the Redwood Creek Restoration Project, begun in 2009, is an attempt to restore the 46-acre creek floodplain. It includes creation of

1590-486: The latter was observed to spawn, raising hopes of a return of a viable spawning run in Redwood Creek. In fall of 2003, the NPS completed the first phase of the Banducci Site restoration project, about 1 km upstream from the creek's mouth at Muir Beach. Artificial log jams were constructed using downed Eucalyptus trees and breaching the constraining levees to reconnect the channel and floodplain. The primary purpose of

1643-601: The many trailheads around Mount Tamalpais are usually open, but during fire season some of these roads may be closed due to high fire risk. The many roads, paved and unpaved, that cross the Mount Tamalpais region are used by mountain bikers , especially on weekends. Mount Tamalpais played an instrumental role in the birth of mountain biking many years ago, with pioneer frame builders such as Tom Ritchey , Gary Fisher, and Joe Breeze setting up shops in nearby towns. There has been considerable controversy over trail access for mountain bikes, both in terms of environmental impact and

1696-633: The middle, foggy elevations due to a thermal inversion . The summer fog and breezes make locations on Mount Tamalpais, closer to the ocean, cooler than the blazing hot interior valleys. Hardwood woodland types are generally subtypes of California oak woodland , including oak-bay-madrone forest, oak woodland, and oak savannah . Oak-bay-madrone forests are found in areas with moderate moisture and particularly favor north-facing slopes. They are dominated by one or more of three hardwood tree species – Coast Live Oak , California bay , and madrone . Coast live oak tends to be dominant in somewhat drier areas, while bay

1749-803: The mountain chamise chaparral and manzanita chaparral. Chamise is dominant in the hottest, most xeric areas of the mountain, particularly on south- and west-facing slopes, while manzanita is dominant in other xeric areas, particularly on east-facing slopes and forest borders. Areas of mixed chamise-manzanita chaparral occur in relatively more mesic areas; Ceanothus and dwarfed interior live oak may also predominate on such sites. Areas in which various kinds of chaparral communities are dominant include areas along Old Railroad Grade. Grassland areas are also common on Mount Tamalpais. Native perennial bunchgrass species were originally dominant, but most of these grasslands are now dominated by invasive annual grasses of European origin. Native grasslands, still found in

1802-480: The mountain in the early 20th century, only to be destroyed by one of the periodic hurricane-force windstorms. In late November 1944, a US Navy plane crashed into the mountain after developing engine trouble shortly after takeoff from Alameda Naval Air Station . All eight aviators on board were killed. The U.S. Weather Bureau operated a weather station at the site of the now defunct Mill Valley Air Force Station for many years. The peak and its surrounding areas are

1855-412: The mountain include various types of hardwood and coniferous forests , coastal scrub , chaparral , grassland , and wetland vegetation. Wholly or partially coniferous forest types are found in the moistest areas of Mount Tamalpais. Coast redwood forests are restricted to areas where the particular ecological needs of redwood are met: areas characterized by high overall moisture, low elevations below

1908-596: The mountain, while High Marsh represents a rare example of a marsh community on the mountain. Serpentine soils have a high rate of endemism and are the site of several unique subtypes of the above plant communities. Serpentine grasslands are some of the few grasslands in which native perennial grasses are still relatively dominant. Serpentine chaparral forms a unique plant community, dominated by dwarfed leather oak ( Quercus durata ), Jepson ceanothus ( Ceanothus jepsonii ), Tamalpais manzanita ( Arctostaphylos montana ), and Sargent cypress ( Cupressus sargentii ). On

1961-430: The mountain. Since the steep slopes of Mount Tamalpais force out moisture from passing storms and/or fog, the mountain supports several year-round streams like Redwood Creek on the southern face of the mountain down into Muir Woods . The steep southeastern slopes of Mount Tamalpais drain to Arroyo Corte Madera del Presidio , which in turn discharges to Richardson Bay . With its height, various faces, and proximity to

2014-538: The name is the Coast Miwok word for "sleeping maiden" and is taken from a " Legend of the Sleeping Maiden " Supposedly, the legend is that the mountain's contour reflects the reclining profile of a young Miwok girl who was saved from a rival tribe by the shuddering of the mountain. However, this legend actually has no basis in Coast Miwok myth and is instead a piece of Victorian-era apocrypha . The "Sleeping Lady" story

2067-541: The north slopes of Mount Tamalpais, including Alpine Lake , Kent Lake , Bon Tempe Lake , Phoenix Lake, and Lake Lagunitas . The western slopes of the mountain descend to the Pacific Ocean at Stinson Beach . The annual Dipsea Race traverses the mountain from Mill Valley to Stinson Beach. Though backpack camping isn't allowed, walk-in camping exists at the Pantoll and Bootjack campgrounds. The historic Bootjack Campground

2120-418: The ocean and bay, the mountain contains many microclimates , ranging from cool and foggy in lower ocean-facing valleys with their redwood forests, to hot and dry on the manzanita slopes, cool and breezy at the summit, and shady on the heavily Douglas-fir -forested north slopes near Alpine Lake. Annual precipitation around Mount Tamalpais varies greatly from around 27.5–31.5 inches (700–800 mm) in

2173-612: The population has shifted to English. According to Catherine A. Callaghan's Bodega Miwok Dictionary , nouns have the following cases , expressed with suffixes: present subjective , possessive , allative , locative , ablative , instrumental , and comitative . Sentences are most commonly subject-verb-object , but Callaghan says that "syntax is relatively free". The following is the Bodega dialect: Phonemes in parentheses are introduced from Spanish loan words. Allophones of introduced sounds, /b ɡ/ include /β ɣ/. This article related to

Redwood Creek provides a critical spawning and rearing habitat for coho or silver salmon ( Oncorhynchus kisutch ), coastal cutthroat ( Oncorhynchus clarki clarki ) and steelhead trout ( Oncorhynchus mykiss ), each of them federally listed species . The creek is near the southernmost limit of coho habitat and the fish have never been stocked, so they have

2279-657: The rest of the California Coast Ranges, Mount Tamalpais is the result of uplift, buckling, and folding of the North American Plate as it slides along the Pacific Plate near the San Andreas Fault zone . In 2004, a team of Penn State geoscientists suggested that a blind thrust fault , like the one that caused the infamous Northridge earthquake , lies beneath Mount Tamalpais. This idea was partly based on

2332-407: The safety of other trail users. As a result, bicycles have been banned from the majority of narrow, single-track trails, though bicycles are still allowed on fire roads. The fire roads on Mt. Tam are mixed-use and they are commonly used as running, hiking, biking and horseback riding routes. The Dipsea Race , the oldest cross-country trail running race in the U.S., is held in the area and part of

2385-523: The sandbar at Muir Beach allowing the fish to move upstream (usually in December and January). No salmon were seen in the 2007-2008 winter run, nor the 2008-2009 winter run. Evidence points to exhaustion of smolt oversummering in the creek due to a loss of large woody debris and deep pools where young salmon can rest. Starting in 2009, the National Park Service will begin restoring Muir Beach to create

2438-778: The steep, south-facing bowl canyon that Muir Woods is located in, with precipitation in Redwood Canyon at around 39.4–47.2 inches (1,000–1,200 mm). As in San Francisco , most of the annual precipitation falls during the winter months. During cold, wet winter storms, the mountain also regularly gets some snowfall, sometimes as much as 6 inches (15 cm) overnight, as observed in February 2001, March 2006, February 2011, February 2019, and February 2023. The region sometimes gets hit with strong Pacific storms that may topple trees, and bring hurricane-force winds to exposed, barren areas like

2491-549: The steepness of Mount Tamalpais and of nearby Bolinas Ridge , such steepness on the visible surface often being the result of blind thrust faults. Another reason for the suggestion was that the San Andreas Fault creeps more slowly south of Mount Tamalpais than it does in its sections north of Mount Tamalpais and in the Olema Valley , and that the existence of a blind thrust fault may explain the different creeping velocities. If

2544-581: The time of European discovery, the watershed was inhabited by the Coast Miwok, of which the local Huimen tribe was one of fifteen independent Miwok tribes in Marin and southern Sonoma counties. The indigenous archeological site named CA-MRN-33 on the edge of Big Lagoon is listed on the National Register of Historic Places as the Muir Beach Historical Site. The Banducci family grew hay and flowers on

2597-690: The top of Mount Tamalpais and therefore never set foot on the peak. Tamalpais was home to the Mount Tamalpais and Muir Woods Railway , also known as "The Crookedest Railroad in the World," a railroad which wound its way from downtown Mill Valley up to the mountain's East Peak, starting in 1896. An auto road was constructed to the peak as automobiles gained popularity in the 1920s. The 8-mile standard-gauge railroad used conventional rails but required mountain-climbing geared steam locomotives and operated from 1896 to 1930. Early wireless towers were constructed on

2650-493: The trail traverses the mountain from Mill Valley to Stinson Beach. Broadway musicals are performed outdoors, several times each summer, in the stone open air Cushing Memorial Amphitheatre on the southern side of Mt. Tam. Coast Miwok language Coast Miwok was one of the Miwok languages spoken in California , from San Francisco Bay to Bodega Bay . The Marin and Bodega varieties may have been separate languages. All of

2703-498: The upper slopes of the mountain, small groves of Sargent cypress trees up to 50 feet (15 m) tall can be found in serpentine areas. Several species of endemic plants are found only on serpentine soils; these species may be widespread, but only occur on serpentine soils, or the may be more restricted, only growing in a few other places besides Mount Tamalpais, or may even be restricted just to Mount Tamalpais. The Mount Tamalpais thistle ( Cirsium hydrophilum var. vaseyi ), for example,
