Pelican 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 has an outflow via the short Pelican Lake Creek southwest through a notch in the coastal cliffs onto Double Point's Bolsa Beach. Pelican Lake is one of the five Coast Trail Lakes, along with Bass Lake, Crystal Lake, Ocean Lake and Wildcat Lake. Alamere Falls is about to the northwest. Geology As with the other nearby lakes in the southeast portion of the Point Reyes peninsula, Pelican 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 Range ...

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.

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''. There may be as many as 1000 scientific papers focused on this species. The genome is (as of 2012) being studied in depth. Description A highly variable plant, taking many forms, ''E. guttata'' is a species complex in that there is room to treat some of its forms as different species by some definitions. The plant ranges from tall with disproportionately large, 2 to 4 cm long, tubular flowers. The perennial form spreads with stolons or rhizomes. The stem may be erect or recumbent. In the latter form, roots may develop at leaf nodes. Sometimes dwarfed, it may be hairless or have some hairs. Leaves are opposite, round to oval, usually coarsely a ...

Baccharis Pilularis
''Baccharis pilularis'', called coyote brush (or bush), chaparral broom, and bush baccharis, is a shrub in the family Asteraceae native to California, Oregon, Washington, and Baja California.

Coyote brush is known as a secondary pioneer plant in communities such as coastal sage scrub and chaparral. It does not regenerate under a closed shrub canopy because seedling growth is poor in the shade. Coast live oak, California bay, '' Rhus integrifolia'', and other shade producing species replace coastal sage scrub and other coyote bush-dominated areas, particularly when there has not been a wildfire or heavy grazing. In California grasslands, it comes in late and invades and increases in the absence of fire or grazing. Coyote bush inv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
