Chuckanut Formation
The Chuckanut Formation in northwestern Washington (named after the Chuckanut Mountains, near Bellingham, Washington, Bellingham), its extension in southwestern British Columbia (the Huntingdon Formation), and various related Geological formation, formations in central Washington (including the Swauk Formation, Swauk, Roslyn Formation, Roslyn, Manastash Formation, Manastash, and Chumstick Formation, Chumstick) are fluvial sedimentary formations of Eocene age, deposited from about to around . The nature of the deposits and included plant fossils indicate a low-lying coastal plain with a subtropical climate; the nature of the sediments indicates metamorphic sources in northeastern Washington. Extent The original Chuckanut/Huntingdon/Swauk formation appears to have been deposited as a single unit in a large basin, and subsequently separated by faulting. The original extent of the formation is unknown, parts having been uplifted and eroded away, and the current extents largely co ...

Sabalites
''Sabalites'' is an extinct genus of palm. Species belonging to the genus lived in the late Cretaceous to Miocene and have been found in South America, North America, Europe, and Asia. The genus is characterized by its costapalmate leaves, which consist of a radial fan of leaves that have individual pronounced midribs (costa). The genus was erected by Gaston de Saporta, who rejected Oswald Heer's previous placement of the relevant fossil species in the genus ''Sabal ''Sabal'' is a genus of palms (or fan-palms) endemic to the New World. Currently, there are 17 recognized species of ''Sabal'', including one hybrid species. The species are native to the subtropical and tropical regions of the Americas, from th ...''.

Metamorphic
Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock (protolith) is subjected to temperatures greater than and, often, elevated pressure of or more, causing profound physical or chemical changes. During this process, the rock remains mostly in the solid state, but gradually recrystallizes to a new texture or mineral composition. The protolith may be an igneous, sedimentary, or existing metamorphic rock. Metamorphic rocks make up a large part of the Earth's crust and form 12% of the Earth's land surface. They are classified by their protolith, their chemical and mineral makeup, and their texture. They may be formed simply by being deeply buried beneath the Earth's surface, where they are subject to high temperatures and the great pressure of the rock layers above. They can also form from tectonic processes such as continental collisions, which cause horizontal pressure, friction, and distorti ...

Turtle
Turtles are an order of reptiles known as Testudines, characterized by a special shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, although many species live in or around water. Turtle shells are made mostly of bone; the upper part is the domed carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scales made of keratin, the material of hair, horns, and claws. The carapace bones develop from ribs that grow sideways and develop into broad flat plates th ...

Seattle
Seattle ( ) is a seaport city on the West Coast of the United States. It is the seat of King County, Washington. With a 2020 population of 737,015, it is the largest city in both the state of Washington and the Pacific Northwest region of North America. The Seattle metropolitan area's population is 4.02 million, making it the 15th-largest in the United States.

Strike-slip
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

Roslyn, Washington
Roslyn is a city in Kittitas County, Washington, United States. The population was 893 at the 2010 census. Roslyn is located in the Cascade Mountains, about 80 miles east of Seattle. The town was founded in 1886 as a coal mining company town. During the 20th century, the town gradually transitioned away from coal, and today its economy is primarily based on forestry and tourism. The town was the filming location for '' The Runner Stumbles'', ''Northern Exposure'', and ''The Man in the High Castle''. Many of the town's historical structures have been preserved, and its downtown was added to the National Register of Historic Places in 1978. History Early history Coal deposits were first noted in the Roslyn area in 1883, with a large vein discovered at the upper Smith Creek canyon in 1885 by C.P. Brosious, Walter J. Reed, and Ignatius A. Navarre. Roslyn was platted in 1886 by Logan M. Bullet, vice president of the Northern Pacific Coal Company, at the time that the company initi ...

Mount Stuart
Mount Stuart is a mountain in the Cascade Range, in the U.S. state of Washington. It is the second highest non-volcanic peak in the state, after Bonanza Peak and seventh-highest overall. Mount Stuart is the highest peak in the Stuart Range, and it is located in the central part of the Washington Cascades, south of Stevens Pass and east of Snoqualmie Pass in the Alpine Lakes Wilderness. Name Mount Stuart was given its name by George B. McClellan in September 1853 in honor of his oldest and best friend, "the late Capt. Jas. immieStuart of the Rifles—a gallant soldier & accomplished gentleman." Stuart had died of an arrow wound on June 18, 1851, following a skirmish with Native Americans at the base of the Siskiyou Mountains in southwest Oregon. Topography Mount Stuart is more notable for its local relief than for its absolute elevation. For example, the south face rises in just 2 horizontal miles (3.2 km). The northeast and northwest sides of the mountain exhibit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
