Siskiyou County, California
Siskiyou County (, ) is a county in the northernmost part of the U.S. state of California. As of the 2020 census, the population was 44,076. Its county seat is Yreka and its highest point is Mount Shasta. It falls within the Cascadia bioregion. Siskiyou County is in the Shasta Cascade region along with the Oregon border. Because of its outdoor recreation, Mt. Shasta, McCloud River, and Gold Rush era history, it is an important tourist destination within the state.

Ice Age
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet. Earth is currently in the Quaternary glaciation. Individual pulses of cold climate within an ice age are termed ''glacial periods'' (or, alternatively, ''glacials, glaciations, glacial stages, stadials, stades'', or colloquially, ''ice ages''), and intermittent warm periods within an ice age are called '' interglacials'' or ''interstadials''. In glaciology, ''ice age'' implies the presence of extensive ice sheets in both northern and southern hemispheres. By this definition, Earth is currently in an interglacial period—the Holocene. The amount of anthropogenic greenhouse gases emitted into Earth's oceans and atmosphere is predicted to prevent the next glacial period for th ...

Knobcone Pine
The knobcone pine, ''Pinus attenuata'' (also called ''Pinus tuberculata''), is a tree that grows in mild climates on poor soils. It ranges from the mountains of southern Oregon to Baja California with the greatest concentration in northern California and the Oregon-California border. Description Individual specimens can live up to a century. The crown is usually conical with a straight trunk. It reaches heights of , but can be a shrub on especially poor sites. The Bark (botany), bark is thin and smooth, flaky and gray-brown when young, becoming dark gray-red-brown and shallowly furrowed into flat scaly ridges in age. The twigs are red-brown and often resinous. Its wood is knotty and of little interest for lumber. The leaves are in fascicles of three, needle-like, yellow-green, twisted, and long. The Conifer cone, cones are resin-sealed and irregularly shaped, long and clustered in Whorl (botany), whorls of three to six on the branches. The scales end in a short stout prickle. ...

Abies Magnifica
''Abies magnifica'', the red fir or silvertip fir, is a western North American fir, native to the mountains of southwest Oregon and California in the United States.

Chrysolepis
''Chrysolepis'' is a small genus of plants in the family Fagaceae, endemic to the western United States. Its two species have the common name chinquapin. The genus occurs from western Washington south to the Transverse Ranges in Southern California, and east into Nevada. Description ''Chrysolepis'' are evergreen trees and shrubs with simple, entire (untoothed) leaves with a dense layer of golden scales on the underside and a thinner layer on the upper side; the leaves persist for 3–4 years before falling. The fruit is a densely spiny cupule containing 1–3 sweet, edible nuts, eaten by the indigenous peoples. The fruit also provides food for chipmunks and squirrels. ''Chrysolepis'' is related to the subtropical southeast Asian genus ''Castanopsis'' (in which it was formerly included), but differs in the nuts being triangular and fully enclosed in a sectioned cupule, and in having bisexual catkins. ''Chrysolepis'' also differs from another allied genus ''Castanea'' (chestnut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canyon Live Oak
''Quercus chrysolepis'', commonly termed canyon live oak, canyon oak, golden cup oak or maul oak, is a North American species of evergreen oak that is found in Mexico and in the western United States, notably in the California Coast Ranges. This tree is often found near creeks and drainage swales growing in moist cool microhabitats. Its leaves are a glossy dark green on the upper surface with prominent spines; a further identification arises from the leaves of canyon live oak being geometrically flat. Description ''Quercus chrysolepis'' is an evergreen tree with significant-sized spreading, horizontal branches, and a broad, rounded crown; it attains a height of 6–30 meters (20–100 feet) and often forms as a shrub. The trunk diameter typically ranges from . Exceptionally large specimens are found in the mountains of Southern California, and rank among the largest oaks in North America.

''Calocedrus'', the incense cedar (alternatively spelled incense-cedar), is a genus of coniferous trees in the cypress family Cupressaceae first described as a genus in 1873. It is native to eastern Asia and western North America. The generic name ''Calocedrus'' means "beautiful cedar". Description The genus is related to the ''Thuja'', and has similar overlapping scale-leaves. ''Calocedrus'' differs from ''Thuja'' in the scale leaves being in apparent whorls of four (actually opposite decussate pairs like ''Thuja'', but not evenly spaced apart as in ''Thuja'', instead with the successive pairs closely then distantly spaced), and in the cones having just 2–3 pairs of moderately thin, erect scales, rather than 4–6 pairs of very thin scales in ''Thuja''.
