Bear River (Humboldt County)
Bear River is the largest Pacific coastal drainage basin between the Mattole River and the Eel River. Bear River drains the ranch pastures and forests of California Coast Ranges south of the Bear River Ridge extending easterly from False Cape along the False Cape shear zone of the Russ Fault. The river channel through undivided Cretaceous marine formations exposes younger Neogene, namely middle or lower Pliocene, marine sedimentary and metasedimentary rocks near the mouth, but lacks the well defined offshore submarine canyons of the Eel River to the north and the Mattole River to the south. Bear River reaches the Pacific after flowing westerly approximately from elevations above along the ridge above the Bull Creek drainage of Humboldt Redwoods State Park. Bear River provides the recreational and industrial water supply for the community of Capetown, California, and wildlife habitat including cold freshwater habitat for fish migration and spawning. Bear River was named from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sedimentary
Sedimentary rocks are types of rock (geology), rock that are formed by the accumulation or deposition of mineral or organic matter, organic particles at Earth#Surface, Earth's surface, followed by cementation (geology), cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of detritus (geology), geological detritus (minerals) or detritus, biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or Mass wasting, mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on ...

Josiah Gregg
Josiah Gregg (19 July 1806 – 25 February 1850) was an American merchant, explorer, naturalist, and author of '' Commerce of the Prairies'', about the American Southwest and parts of northern Mexico. He collected many previously undescribed plants on his merchant trips and during the Mexican–American War, for which he has often been credited in botanical nomenclature. After the war he went to California, where he reportedly died of a fall from his mount due to starvation near Clear Lake on 25 February 1850, following a cross-country expedition which fixed the location of Humboldt Bay. Early years Josiah Gregg was born on July 19, 1806, in Overton County, Tennessee, the youngest son of seven children of Harmon and Susannah (Smelser) Gregg.Palmquist, Peter E., Thomas R.

Humboldt Redwoods State Park
Humboldt Redwoods State Park is a state park of California, United States, containing Rockefeller Forest, the world's largest remaining contiguous old-growth forest of Sequoia sempervirens, coast redwoods. It is located south of Eureka, California, near Weott, California, Weott in southern Humboldt County, California, Humboldt County, within Northern California, named after the great nineteenth-century scientist, Alexander von Humboldt. The park was established by the Save the Redwoods League in 1921 largely from lands purchased from the Pacific Lumber Company.

Bull Creek (Humboldt County)
Bull Creek is the largest Eel River tributary drainage basin preserved within Humboldt Redwoods State Park. The basin contains the world's largest remaining contiguous old-growth forest of coast redwoods. Bull Creek flows in a clockwise semi-circle around 3373-foot (1028-meter) Grasshopper Mountain to enter the South Fork Eel River approximately 1.5 miles (2.5 km) upstream of the South Fork confluence with the Eel River. Old-growth forest The forest that grows in the alluvial flats along Bull Creek contain the highest recorded biomass of any forest in the world. This forest also has as the world's highest canopy—as measured by the average height of the mature trees. The average height of canopy trees along Bull Creek exceeds 300 feet (91 meters), and several trees in this forest exceed 360 feet (110 meters). The forest canopy is dominated by mature coast redwoods, many of which are over 1000 years old. Smaller populations of Tanoak, California laurel, and Douglas fir ar ...

Submarine Canyon
A submarine canyon is a steep-sided valley cut into the seabed of the continental slope, sometimes extending well onto the continental shelf, having nearly vertical walls, and occasionally having canyon wall heights of up to 5 km, from canyon floor to canyon rim, as with the Great Bahama Canyon. Just as above-sea-level canyons serve as channels for the flow of water across land, submarine canyons serve as channels for the flow of turbidity currents across the seafloor. Turbidity currents are flows of dense, sediment laden waters that are supplied by rivers, or generated on the seabed by storms, submarine landslides, earthquakes, and other soil disturbances. Turbidity currents travel down slope at great speed (as much as 70 km/h), eroding the continental slope and finally depositing sediment onto the abyssal plain, where the particles settle out.Continental Margin Sedimentation: From Sediment Transport to Sequence Stratigraphy (Special Publication 37 of the IAS) Ma ...

Metasedimentary
In geology, metasedimentary rock is a type of metamorphic rock. Such a rock was first formed through the deposition and solidification of sediment Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles. For example, sand an .... Then, the rock was buried underneath subsequent rock and was subjected to high pressures and temperatures, causing the rock to recrystallize. The overall composition of a metasedimentary rock can be used to identify the original sedimentary rock, even where they have been subject to high-grade metamorphism and intense deformation.
