Garfield Peak (Oregon)
Garfield Peak is a mountain peak on the south end of Crater Lake in Crater Lake National Park, Oregon. The top of the peak reaches above sea level. The peak has a elevation trail to the summit from the Crater Lake lodge, one of the most popular hiking sites surrounding the lake. The trail continues east toward Applegate peak ( high). The peak is one of seven peaks on Crater Lake's rim to rise above . History The Garfield Peak was named in honor of James Rudolph Garfield, the Secretary of Interior for President Theodore Roosevelt, who created the national park in 1902. Garfield visited the park in 1907, the first cabinet member to visit Crater Lake. Geology Garfield Peak was created after Mount Mazama, a large stratovolcano, erupted violently approximately 7,700 years ago, formed on the rim of its caldera which now contains Crater Lake. The walls along the southern rim of Crater Lake have had a peculiar influence from sulfur steams coming off fumaroles, which color the r ...

Stratovolcano
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as . Stratovolcanoes are sometimes called composite volcanoes because of their composite stratified structure, built up from sequential outpourings of erupted materials. They are among the most common types of volcanoes, in contrast to the less common shield volca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dark-eyed Junco
The dark-eyed junco (''Junco hyemalis'') is a species of junco, a group of small, grayish New World sparrows. This bird is common across much of temperate North America and in summer ranges far into the Arctic. It is a very variable species, much like the related fox sparrow (''Passerella iliaca''), and its systematics are still not completely untangled. Taxonomy The dark-eyed junco was formally described by the Swedish naturalist Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'' as ''Fringilla hyemalis''. The description consisted merely of the laconic remark "''F ingillanigra, ventre albo.'' ("A black 'finch' with white belly") and a statement that it came from America. Linnaeus based his description on the "Snow-Bird" that Mark Catesby had described and illustrated in his ''The Natural History of Carolina, Florida and the Bahama Islands''. The Bill of this Bird is white: The Breast and Belly white. All the rest of the Body black; but in some places dusky, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow-bellied Marmot
The yellow-bellied marmot (''Marmota flaviventris''), also known as the rock chuck, is a large, stout-bodied ground squirrel in the marmot genus.

American Pika
The American pika (''Ochotona princeps''), a diurnality, diurnal species of pika, is found in the mountains of western North America, usually in boulder fields at or above the tree line. They are herbivorous, smaller relatives of rabbits and hares. Pikas have two different ways of foraging; they either directly consume food or they cache food in piles for the winter (haying). Pikas are vocal, using both calls and songs to warn when predators are nearby and during the Estrous cycle, breeding season. Predators of the pika include eagles, hawks, coyotes, bobcats, foxes, and weasels. Recent studies suggest some populations are declining due to habitat loss and global warming. They generally cannot tolerate temperatures above . Currently the American pika is considered a species of least concern. Description American pikas, known in the 19th century as "little Chief hares", have a small, round, ovate body. Their body lengths range from . Their hind feet range from 25 to 35 mm ...

Pinus Albicaulis
''Pinus albicaulis'', known by the common names whitebark pine, white bark pine, white pine, pitch pine, scrub pine, and creeping pine, is a conifer tree native to the mountains of the western United States and Canada, specifically subalpine areas of the Sierra Nevada, Cascade Range, Pacific Coast Ranges, and Rocky Mountains. It shares the common name "creeping pine" with Creeping pine, several other plants. The whitebark pine is typically the highest-elevation pine tree found in these mountain ranges and often marks the tree line. Thus, it is often found as ''krummholz'', trees growing close to the ground that have been dwarfed by exposure. In more favorable conditions, the trees may grow to in height. Identification Whitebark pine is a member of the Pinus classification, white pine group, the ''Pinus'' subgenus ''Strobus'', and the section ''Strobus''; like all members of this group, the leaves (needles) are in fascicle (botany), fascicles (bundles) of five with a decidu ...

Hematite
Hematite (), also spelled as haematite, is a common iron oxide compound with the formula, Fe2O3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of . It has the same crystal structure as corundum () and ilmenite (). With this it forms a complete solid solution at temperatures above . Hematite naturally occurs in black to steel or silver-gray, brown to reddish-brown, or red colors. It is mined as an important ore mineral of iron. It is electrically conductive. Hematite varieties include ''kidney ore'', ''martite'' (pseudomorphs after magnetite), ''iron rose'' and ''specularite'' (specular hematite). While these forms vary, they all have a rust-red streak. Hematite is not only harder than pure iron, but also much more brittle. Maghemite is a polymorph of hematite (γ-) with the same chemical formula, but with a spinel structure like magnetite. Large deposits of hematite are found in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
