	CA10196 - Trinity Dam - California
		The state of crustal stress in the Klamath Mountains is poorly defined, due to the near absence of recorded seismicity prior to 1983, when the USBR monitoring effort began (Zoback and Zoback, 1980; USBR, 1984a).
		Trinity Dam is located on the eastern Klamath plate, the oldest and easternmost of four eastward-dipping thrust sheets that comprise the Klamath Mountains province.
		Rocks of the eastern Klamath plate are Devonian to Jurassic metavolcanic and metasedimentary rocks that are underlain by widespread sheets of ultramafic rocks, and have been intruded by Jurassic to Cretaceous granitic stocks and batholiths.

	Klamath Mountains - Wikipedia, the free encyclopedia
		The Klamath Mountains are a mountain range in northwest California and southwest Oregon, the highest peaks being Mount Eddy (2744m / 9002') in Trinity County, California, and Mount Ashland (2296m / 7533') in Jackson County, Oregon.
		They have a very varied geology, with substantial areas of serpentine and marble, and a climate characterised by cold winters with very heavy snowfall, and warm summers with limited rainfall.
		The northernmost range of the Klamath Mountains are known as the Siskiyou Mountains.

	Klamath River - Wikipedia, the free encyclopedia
		The Klamath River, approximately 250 mi (400 km) long, is a major river of the Pacific coast in southern Oregon and northern California in the United States.
		Below Klamath Falls, the water of the river, along with that of the nearby Lost River, is extensively diverted for irrigation within the 230,000 acre (930 km²) federal Klamath Irrigation Project.Much of the lower course of the river in California is within the Klamath National Forest.
		A separate controversy on the river surrounds the removal of water from Upper Klamath Lake for irrigated agriculture, which was temporarily halted in 2001 to protect endangered salmon and lake fish during a record-breaking drought.

		The Klamath Economic Zone, which includes the Klamath Ecoregion as well as the Rogue River drainage to the north, is managed as one unit for purposes of allocating ocean salmon harvesting since stocks from these rivers are found together in the ocean fishery.
		A principal feature of the Klamath Mountains is the presence of "peneplains" which are elevated land masses with flattish or gently rounded summits with an approximate accordance in the altitudes of even-crested ridges, given the appearance of a dissected plateau.
		The Klamath Ecoregion is somewhat unique in that the European invasions of the last 500 years came from quite different directions: the Russians moving across the Bering Strait and down the coast, the Spanish working their way up California from Mexico, and the Americans moving across the continent from the east.

	California's Coastal Mountains
		The northern-most is the Klamath Mountains province, which lies near the coast in northwestern Del Norte County and extends north into Oregon.
		In Northern California, the Klamath Mountains are composed of metamorphic and granitic rock--formed as a result of extreme changes in temperature, pressure, and chemical composition that occurred when molten material from below the earth's crust was pushed to the surface.
		South of the Klamath Mountains, the Coast Ranges lie close to the continent's edge, from Humboldt County to San Francisco Bay, forming a series of low mountains paralleling the coast.

	The Mamaís and Papaís
		The northernmost are the Siskiyou Mountains, drained primarily by the Smith River.
		The Klamath region batholithic rock (granitic) was formed by a subduction, this material intruded into a series of prebatholithic metamorphic rocks in the long belts west of the plutonic rocks.
		The geology of the mountains of the Klamath Province is similar in origin and structure to the Sierra Nevada.

	California Geological Overview (Site not responding. Last check: 2007-10-30)
		The bedrock geology of the Klamaths disappears beneath the young cover of the Cascades and the sediments of the so-called Lassen Straits to the east; similarly, the Sacramento Valley sediments lap onto the Klamaths and form the southern range boundary.
		Subdivision of the Klamaths into these terranes is complicated by the fact that exposures are sometimes sparse because of rainfall (often more than 250 cm)and the resultant deep weathering and vegetative cover, and additionally are often highly metamorphosed from the intrusion of many plutons.
		The Trinity ophiolite separates the Eastern Klamath Plate from the so-called Central Metamorphic Plate that lies structurally beneath it; this ophiolite is thus the easternmost of the Klamath Mountains ophiolites.

	Correlation of the Klamath Mountains and Sierra Nevada
		The sequence shown for the Klamath Mountains is modified from Irwin and Mankinen (1998) and Irwin and Wooden (1999).
		In the Klamath Mountains, the Eastern Klamath terrane, which consists of the Yreka, Trinity and Redding subterranes, was the backstop for the Central Metamorphic and younger accretionary episodes, and displays a remarkable record of sedimentation, volcanism and plutonism from Silurian-Devonian to Jurassic time.
		Examples of this in the Klamath Mountains are the Devonian Salmon and Abrams Schists of the Central Metamorphic terrane, the Triassic(?) schist of the Fort Jones terrane, and the Early Cretaceous South Fork Mountain Schist that structurally underlies Klamath Mountains terranes along much of the western edge of the province.

	SummitPost - Salmon Mountain -- Climbing, Hiking & Mountaineering
		Salmon Mountain is the highpoint of California’s storied Humboldt County, a land of towering redwoods, renowned cannabis, & controversial claims of bigfoot sightings.
		Despite its relatively low overall elevation, Salmon Mountain’s (& Mountains’) proximity to the ocean ensures enough precipitation during the winter to keep patches of the heavy, white frozen stuff on the mountain until after June, even during low snow years (this area was glaciated during the last ice age).
		Salmon Mountain is named so perhaps because of the enormous number of fish of the same name that used to fill many of the larger rivers that the peak overlooks, making their seasonal trek to the ocean, to return before dying.

		The conventional geologic map (rock units are mapped but the context is not that of terrane units) is shown and the map that characterizes the assemblage of stratigraphic units as distinct terranes is presented.
		Two examples of exceptions are the deep purple unit (Jui), which is actually outliers of ultramafic (ophiolitic) lavas, once part of oceanic crust, which appear similar in the field but originated locally within their terranes, and the pinkish-red unit, which consists of intrusive rocks that invaded several terranes, already in place.
		We proffer a preview of the topographic expression of the Klamath Mountains, which will be presented in Landsat format shortly, by this enlargement of the area made from the same DEM data.

		Easily visible on the photo is the winding channel of the Klamath (California's third largest river, after the Colorado and Sacramento), entering the state across the top of the image from Oregon, disgorging into the Pacific at lower left.
		The mountains of the Klamaths, contrariwise, are over 100 million years old — a factor of a thousandfold older.
		The Klamath Mountains are remote and neglected even by Californians, since when natives think of going to the mountains, they typically think of the Sierras, while if the idea of the far north of California enters into their cognition, they then usually think of Mount Shasta.
