An inselberg or monadnock (/məˈnædnɒk/ mə-NAD-nok) is an isolated rock hill, knob, ridge, or small mountain that rises abruptly from a gently sloping or virtually level surrounding plain. In Southern Africa a similar formation of granite is known as a koppie, an Afrikaans word ("little head") from the Dutch diminutive word kopje. If the inselberg is dome-shaped and formed from granite or gneiss, it can also be called a bornhardt, though not all bornhardts are inselbergs. An inselberg results when a body of rock resistant to erosion, such as granite, occurring within a body of softer rocks, is exposed by differential erosion and lowering of the surrounding landscape.

The Granite Mountains are a short subrange of the Rocky Mountains in central Wyoming of the United States. The range runs approximately 100 mi (160 km) E-W along the south side of the Shoshone Basin, and north of the Sweetwater River, in eastern Fremont County and western Natrona County. The highest point is McIntosh Peak at 8,058 feet (2,456 m). Independence Rock is at the east end of the range, and Split Rock was a prominent landmark on the Oregon Trail. The region is rich in uranium and other mineral deposits. (Full article...)

A mound is a heaped pile of earth, gravel, sand, rocks, or debris. Most commonly, mounds are earthen formations such as hills and mountains, particularly if they appear artificial. A mound may be any rounded area of topographically higher elevation on any surface. Artificial mounds have been created for a variety of reasons throughout history, including habitation (see Tell and Terp), ceremonial (platform mound), burial (tumulus), and commemorative purposes (e.g. Kościuszko Mound).

Climbing is a major US-based rock climbing magazine first published in 1970. In 2007, it was bought by Skram Media, the publisher of Urban Climber Magazine. The headquarters of the magazine is in Boulder, Colorado. It is published nine times a year. Climbing was purchased by Outside in 2021. (Full article...)

Ice is water that is frozen into a solid state, typically forming at or below temperatures of 0 °C, 32 °F, or 273.15 K. It occurs naturally on Earth, on other planets, in Oort cloud objects, and as interstellar ice. As a naturally occurring crystalline inorganic solid with an ordered structure, ice is considered to be a mineral. Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color.

Virtually all of the ice on Earth is of a hexagonal crystalline structure denoted as ice I_h (spoken as "ice one h"). Depending on temperature and pressure, at least nineteen phases (packing geometries) can exist. The most common phase transition to ice I_h occurs when liquid water is cooled below 0 °C (273.15 K, 32 °F) at standard atmospheric pressure. When water is cooled rapidly (quenching), up to three types of amorphous ice can form. Interstellar ice is overwhelmingly low-density amorphous ice (LDA), which likely makes LDA ice the most abundant type in the universe. When cooled slowly, correlated proton tunneling occurs below −253.15 °C (20 K, −423.67 °F) giving rise to macroscopic quantum phenomena. (Full article...)
