Bass Lake (Marin County, California)
Bass Lake is a small lake in the southern portion of the Point Reyes National Seashore, northwest of Bolinas. The lake sits at an elevation of and flows out south to the ocean via a creek. Bass Lake is the largest of the five Coast Trail Lakes, which also include Pelican Lake, Crystal Lake, Ocean Lake and Wildcat Lake. Geology Much like the other nearby lakes in the southeast portion of the Point Reyes peninsula, Bass Lake occupies a natural synclinal depression formed behind blocks of rock displaced by landslides within the past 10,000 years. The depressions forming Crystal, Pelican and Bass lakes appear to have been caused by the Double Point Slide, which covers an area of about . The rocks involved in the landslide are shale, chert and sandstone, some similar to Miocene rocks of the Monterey Formation and others to Pliocene rocks from the Central Coast Ranges. The process that caused these slides is ongoing, with several nearby slides caused by the 1906 San Francisco eart ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

California Coast Ranges
The Coast Ranges of California span from Del Norte or Humboldt County, California, south to Santa Barbara County. The other three coastal California mountain ranges are the Transverse Ranges, Peninsular Ranges and the Klamath Mountains. Physiographically, they are a section of the larger Pacific Border province, which in turn is part of the larger Pacific Mountain System physiographic division. UNESCO has included the "California Coast Ranges Biosphere Reserve" in its Man and the Biosphere Programme of World Network of Biosphere Reserves since 1983. * Physiography The northern end of the California Coast Ranges overlap the southern end of the Klamath Mountains for approximately 80 miles on the west. They extend southward for more than 600 miles to where the coastline turns eastward along the Santa Barbara Channel, around the area of Point Conception. Here the southern end meets the Los Angeles Transverse Ranges, or ''Sierras de los Angeles''. The rocks themselves that com ...

Schoenoplectus Californicus
''Schoeneoplectus californicus'' is a species of sedge known by the common names California bulrush, southern bulrush and giant bulrush.

Schoenoplectus Acutus
''Schoenoplectus acutus'' ( syn. ''Scirpus acutus, Schoenoplectus lacustris, Scirpus lacustris'' subsp. ''acutus''), called tule , common tule, hardstem tule, tule rush, hardstem bulrush, or viscid bulrush, is a giant species of sedge in the plant family Cyperaceae, native to freshwater marshes all over North America. The common name derives from the Nāhuatl word ''tōllin'' , and it was first applied by the early settlers from New Spain who recognized the marsh plants in the Central Valley of California as similar to those in the marshes around Mexico City. Tules once lined the shores of Tulare Lake in California, formerly the largest freshwater lake in the western United States. It was drained by land speculators in the 20th century. The expression "out in the tules" is still common, deriving from the dialect of old Californian families and meaning "where no one would want to live", with a touch of irony. The phrase is comparable to "out in the boondocks". ''Schoenoplectus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Willow
Willows, also called sallows and osiers, from the genus ''Salix'', comprise around 400 speciesMabberley, D.J. 1997. The Plant Book, Cambridge University Press #2: Cambridge. of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions. Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow (from Old English ''sealh'', related to the Latin word ''salix'', willow). Some willows (particularly arctic and alpine species) are low-growing or creeping shrubs; for example, the dwarf willow (''Salix herbacea'') rarely exceeds in height, though it spreads widely across the ground. Description Willows all have abundant watery bark sap, which is heavily charged with salicylic acid, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to live ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lupinus Arboreus
''Lupinus arboreus'', the yellow bush lupine (US) or tree lupin (UK), is a species of flowering plant in the legume family Fabaceae. Description ''Lupinus arboreus'' is an evergreen shrub growing to tall (hence the alternative common name, tree lupine) in sheltered situations, but more typically tall. It is capable of tolerating temperatures down to −12 °C and living for up to seven years. It has green to gray-green palmate leaves, with 5–12 leaflets per leaf. The leaflets are long, often sparsely covered with fine silky hairs. In spring it bears many racemes, long, of fragrant, soft yellow, pea-like flowers. Both yellow and lilac to purple flowering forms are known. However, the yellow form is more common, except in the north of the species' range. Distribution The shrub is indigenous to California, US, where it is widely distributed among coastal sage scrub and sand dunes. Because it has been widely introduced in the state, there is some uncertainty about its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mimulus Guttatus
''Erythranthe guttata'', with the common names seep monkeyflower and common yellow monkeyflower, is a yellow bee-pollinated annual or perennial plant. It was formerly known as ''Mimulus guttatus''. ''Erythranthe guttata'' is a model organism for biological studies, and in that context is still referred to as ''Mimulus guttatus''.
