Bald Rock, California
Bald Rock is a granite summit located in Butte County, California, in the Plumas National Forest. Located close to Lake Oroville, the dome peak overlooks Sacramento Valley and coastal mountain ranges. History The area was once home to the Maidu, a tribe of indigenous people. They left the rock with many unique features, such as, metate, grinding holes used to prepare acorns and grains. Recreation A short trail leads through the woods to the rock, which includes several crevasses and peculiar rock formations. The area is used for hiking, climbing, and rappeling. Camping is allowed but not closer than 300 yards from running water. The site also includes the ruin of a small shelter made from stacked rocks.

Butte County, California
Butte County () is a county located in the northern part of the U.S. state of California. In the 2020 census, its population was 211,632. The county seat is Oroville. Butte County comprises the Chico, CA metropolitan statistical area. It is in the California Central Valley, north of the state capital of Sacramento. Butte County is drained by the Feather River and the Sacramento River. Butte Creek and Big Chico Creek are additional perennial streams, both tributary to the Sacramento. The county is home to California State University, Chico and Butte College. History Butte County is named for the Sutter Buttes in neighboring Sutter County; ''butte'' means "small knoll" or "small hill" in French. Butte County was incorporated as one of California's 19 original counties on February 18, 1850. The county went across the present limits of the Tehama, Plumas, Colusa, and Sutter Counties. Between November 8 and 25, 2018, a major wildfire, the Camp Fire, destroyed most of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crevasses
A crevasse is a deep crack, that forms in a glacier or ice sheet that can be a few inches across to over 40 feet. Crevasses form as a result of the movement and resulting stress associated with the shear stress generated when two semi-rigid pieces above a plastic substrate have different rates of movement. The resulting intensity of the shear stress causes a breakage along the faces. Description Crevasses often have vertical or near-vertical walls, which can then melt and create seracs, arches, and other ice formations. These walls sometimes expose layers that represent the glacier's stratigraphy. Crevasse size often depends upon the amount of liquid water present in the glacier. A crevasse may be as deep as 45 metres and as wide as 20 metres. by |
Mountains Of Butte County, California
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Granite Domes
Granite domes are domical hills composed of granite with bare rock exposed over most of the surface. Generally, domical features such as these are known as bornhardts. Bornhardts can form in any type of plutonic rock but are typically composed of granite and granitic gneiss. As granitic plutons cool kilometers below the Earth's surface, minerals in the rock crystallize under uniform confining pressure. Erosion brings the rock closer to Earth's surface and the pressure from above the rock decreases; as a result the rock fractures. These fractures are known as exfoliation joints, or sheet fractures, and form in onionlike patterns that are parallel to the land surface. These sheets of rock peel off the exposed surface and in certain conditions develop domical structures. Additional theories on the origin of granite domes involve scarp-retreat and tectonic uplift. Sheet fractures Sheet fractures are arcuate fractures defining slabs of rock that range from 0.5 to 10 meters thic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

American Black Bear
The American black bear (''Ursus americanus''), also called simply a black bear or sometimes a baribal, is a medium-sized bear endemic to North America. It is the continent's smallest and most widely distributed bear species. American black bears are omnivores, with their diets varying greatly depending on season and location. They typically live in largely forested areas, but will leave forests in search of food, and are sometimes attracted to human communities due to the immediate availability of food. The International Union for Conservation of Nature (IUCN) lists the American black bear as a least-concern species, due to its widespread distribution and a large population estimated to be twice that of all other bear species combined. Along with the brown bear (''Ursus arctos''), it is one of only two modern bear species not considered by the IUCN to be globally threatened with extinction. Taxonomy and evolution Despite living in North America, American black bears are not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Lion
The cougar (''Puma concolor'') is a large cat native to the Americas. Its range spans from the Canadian Yukon to the southern Andes in South America and is the most widespread of any large wild terrestrial mammal in the Western Hemisphere. It is an adaptable, generalist species, occurring in most American habitat types. This wide range has brought it many common names, including puma, mountain lion, catamount and panther (for the Florida sub-population). It is the second-largest cat in the New World, after the jaguar (''Panthera onca''). Secretive and largely solitary by nature, the cougar is properly considered both nocturnal and crepuscular, although daytime sightings do occur. Despite its size, the cougar is more closely related to smaller felines, including the domestic cat (''Felis catus'') than to any species of the subfamily Pantherinae. The cougar is an ambush predator that pursues a wide variety of prey. Primary food sources are ungulates, particularly deer, but it ...

Deer
Deer or true deer are hoofed ruminant mammals forming the family Cervidae. The two main groups of deer are the Cervinae, including the muntjac, the elk (wapiti), the red deer, and the fallow deer; and the Capreolinae, including the reindeer (caribou), white-tailed deer, the roe deer, and the moose. Male deer of all species (except the water deer), as well as female reindeer, grow and shed new antlers each year. In this they differ from permanently horned antelope, which are part of a different family (Bovidae) within the same order of even-toed ungulates (Artiodactyla). The musk deer (Moschidae) of Asia and chevrotains (Tragulidae) of tropical African and Asian forests are separate families that are also in the ruminant clade Ruminantia; they are not especially closely related to Cervidae. Deer appear in art from Paleolithic cave paintings onwards, and they have played a role in mythology, religion, and literature throughout history, as well as in heraldry, such as ...

Snakes
Snakes are elongated, limbless, carnivorous reptiles of the suborder Serpentes . Like all other squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads (cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, although this rule is not universal (see Amphisbaenia, D ...

Rappeling
Abseiling ( ; ), also known as rappelling ( ; ), is the controlled descent of a steep slope, such as a rock face, by moving down a rope. When abseiling the person descending controls their own movement down the rope, in contrast to lowering off in which the rope attached to the person descending is paid out by their belayer. This technique is used by climbers, mountaineers, cavers, canyoners, search and rescue and rope access technicians to descend cliffs or slopes when they are too steep and/or dangerous to descend without protection. Many climbers use this technique to protect established anchors from damage. Rope access technicians also use this as a method to access difficult-to-reach areas from above for various industrial applications like maintenance, construction, inspection and welding. To descend safely, abseilers use a variety of techniques to increase the friction on the rope to the point where it can be controlled comfortably. These techniques range fro ...

Metate
A metate (or mealing stone) is a type or variety of quern, a ground stone tool used for processing grain and seeds. In traditional Mesoamerican cultures, metates are typically used by women who would grind nixtamalized maize and other organic materials during food preparation (e.g., making tortillas). Similar artifacts have been found in other regions, such as the sil-batta in Bihar and Jharkhand, India as well as other grinding stones in China. Design and use While varying in specific morphology, metates are typically made of a large stone with a smooth depression or bowl worn into the upper surface. Materials are ground on the metate using a smooth hand-held stone known as a ''mano'' or ''metlapil''. This action consists of a horizontal grinding motion that differs from the vertical crushing motion used in a mortar and pestle. The depth of the bowl varies, though they are typically not deeper than those of a mortar; deeper metate bowls indicate either a longer period of use ...
