Little Regret Peak
Little Regret Peak is an mountain summit located in Custer County, Idaho, United States. Description Little Regret Peak is part of the Lost River Range which is a subset of the Rocky Mountains. The mountain is set on land managed by Salmon–Challis National Forest. Neighbors include No Regret Peak one mile south, line parent Mount Breitenbach, 1.75 mile south-southeast, Mount Corruption two miles north, Leatherman Peak three miles to the west, and Borah Peak, the highest peak in Idaho, is seven miles to the northwest. Precipitation runoff from the mountain's slopes drains to Pahsimeroi River. Topographic relief is significant as the summit rises above the East Fork Pahsimeroi in one mile. Climate Based on the Köppen climate classification, Little Regret Peak is located in an alpine subarctic climate zone with long, cold, snowy winters, and cool to warm summers. Winter temperatures can drop below −10 °F with wind chill factors below −30 °F. See also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Line Parent
A peak's line parent is the closest higher peak on the highest ridge leading away from the peak's "key col". A col is the lowest point on the ridge between two summits and is roughly synonymous with pass, gap, saddle and notch. The highest col of a peak is its key col. If there is more than one ridge which can be followed to a higher peak then the line parent is the peak closest to the key col. Usually, a line parent must meet some prominence criteria, which might vary depending on the author and the location of the peak. There are at least two other kinds of peak parentage. Island parentage, which is also referred to as encirclement or topographic parentage; and source parentage. See also * Topographic prominence In topography, prominence (also referred to as autonomous height, relative height, and shoulder drop in US English, and drop or relative height in British English) measures the height of a mountain or hill's summit relative to the lowest contou ...

Mountains Of Custer County, Idaho
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 ...

Subarctic Climate
The subarctic climate (also called subpolar climate, or boreal climate) is a climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50° to 70°N, poleward of the humid continental climates. Subarctic or boreal climates are the source regions for the cold air that affects temperate latitudes to the south in winter. These climates represent Köppen climate classification ''Dfc'', ''Dwc'', ''Dsc'', ''Dfd'', ''Dwd'' and ''Dsd''. Description This type of climate offers some of the most extreme seasonal temperature variations found on the planet: in winter, temperatures can drop to below and in summer, the temperature may exceed . However, the summers are short; no more than three months of the year (but at least one month) must have a 24-hour average temperature of at least to fall into this category of climate, and the coldest month should ave ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Topographic Relief
Terrain or relief (also topographical relief) involves the vertical and horizontal dimensions of land surface. The term bathymetry is used to describe underwater relief, while hypsometry studies terrain relative to sea level. The Latin word (the root of ''terrain'') means "earth." In physical geography, terrain is the lay of the land. This is usually expressed in terms of the elevation, slope, and orientation of terrain features. Terrain affects surface water flow and distribution. Over a large area, it can affect weather and climate patterns. Importance The understanding of terrain is critical for many reasons: * The terrain of a region largely determines its suitability for human settlement: flatter alluvial plains tend to have better farming soils than steeper, rockier uplands. * In terms of environmental quality, agriculture, hydrology and other interdisciplinary sciences; understanding the terrain of an area assists the understanding of watershed boundaries, drai ...

Surface Runoff
Surface runoff (also known as overland flow) is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or man-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry man-made contaminants or natural forms of pollution (such as rotting leaves). Man-made contaminants in runoff i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borah Peak
Borah Peak, also known as Mount Borah or Beauty Peak, is the highest mountain in the U.S. state of Idaho and one of the most prominent peaks in the contiguous United States. It is located in the central section of the Lost River Range, within the Challis National Forest in eastern Custer County. On February 11, 2021, the USGS officially recognized Mt. Borah as Idaho's only active glacier. Description The mountain was nameless until it was discovered to be higher than Hyndman Peak, previously regarded as the state's highest point. In February 1934, the U.S. Geological Survey named it for William Borah, the prominent senior U.S. Senator from Idaho, who had served for nearly 27 years at the time and was dean of the Senate. An outspoken isolationist, the "Lion of Idaho" ran for president two years later in 1936, but did not win the Republican nomination, and died in office in 1940. 1983 earthquake The 1983 Borah Peak earthquake occurred on Friday, October 28, at 8:06:09 MDT in ...
