Higher Spire
Higher Spire is a summit in Alaska, United States. Description Higher Spire is located north of Palmer, Alaska, in the Talkeetna Mountains and in the Hatcher Pass Management Area of the state park system. Precipitation runoff from this peak drains south to the Little Susitna River via Reed Creek, whereas the north side drains to Bartholf Creek which is a tributary of the Kashwitna River. Topographic relief is significant as the summit rises above Lower Reed Lake in . The nearest higher neighbor is Lynx Peak to the east. The Snowbird Hut on the northern edge of the Snowbird Glacier provides shelter and access for climbing Higher Spire and Lower Spire. This peak's toponym has been featured in publications since at least 1969,''Scree'' Nick Parker, Mountaineering Club o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lynx Peak
Lynx Peak is a summit in Alaska, United States. Description Lynx Peak is located north of Palmer, Alaska, in the Talkeetna Mountains and in the Hatcher Pass Management Area of the state park system. Precipitation runoff from this mountain's south slope drains into headwaters of the Little Susitna River, whereas the west side drains to Reed Creek which flows to the Little Susitna, and the north slope drains to Bartholf Creek which is a tributary of the Kashwitna River. Topographic relief is significant as the summit rises above the Little Susitna River in . The nearest higher neighbor is Troublemint Peak to the east. The approach to the peak is via the 4.3-mile-long Reed Lakes Trail. On November 15, 1957, a Boeing B-29 Superfortress variants#TB-29, B-29 Superfortress crashed in bad weather about 800 feet below the summit of Lynx Peak on the Bomber Glacier, killing six of the ten people aboard.

Summit
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. For summits that are permanently covered in significant layers of ice, the height may be measured by the highest point of rock (rock height) or the highest point of permanent solid ice (snow height). The highest summit in the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Topographic Relief
Terrain (), alternatively relief or topographical relief, is the dimension and shape of a given surface of land. 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. Bathymetry is the study of underwater relief, while hypsometry studies terrain relative to sea level. 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, drainage characteristics, drainage systems, groundwater systems, water ...

Snowbird Glacier
__NOTOC__ Snowbird Glacier is a hanging alpine glacier in the Talkeetna Mountains of Alaska. Location and terrain Snowbird Glacier is located near the southwestern corner of the Talkeetna Mountains of Alaska. It sits in a high alpine bowl surrounded by largely unnamed rugged granite peaks, glaciers, and canyons. Snowbird Glacier is located in a high alpine zone characterized by rock, ice, and minimal vegetation. Human activity and recreation During the winter and spring, Snowbird Glacier is often visited by backcountry skiers and snowmachiners. During the summer and fall, the glacier is frequented by hikers and backpackers. The glacier lies on the popular Bomber Traverse in the Talkeetna Mountains, which connects several remote mountain huts. During winter months, adjacent peaks and snowfields may be subject to avalanches. Snowbird Glacier is generally considered safe to travel on during summer months without technical gear, though light crampons or Yaktrax will significantly ...

Topographical Prominence
In topography, prominence or relative height (also referred to as autonomous height, and shoulder drop in US English, and drop in British English) measures the height of a mountain or hill's summit relative to the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit. The key col ("saddle") around the peak is a unique point on this contour line and the ''parent peak'' (if any) is some higher mountain, selected according to various criteria. Definitions The prominence of a peak is the least drop in height necessary in order to get from the summit to any higher terrain. This can be calculated for a given peak in the following manner: for every path connecting the peak to higher terrain, find the lowest point on the path; the ''key col'' (or ''highest saddle'', or ''linking col'', or ''link'') is defined as the highest of these points, along all connecting paths; the prominence is the difference between the ...

Köppen Climate Classification
The Köppen climate classification divides Earth climates into five main climate groups, with each group being divided based on patterns of seasonal precipitation and temperature. 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'' indicates a tropical rainforest climate. The system assigns a temperature subgroup for all groups other than those in the ''A'' group, indicated by the third letter for climates in ''B'', ''C'', ''D'', and the second letter for climates in ''E''. Other examples include: ''Cfb'' indicating an oceanic climate with warm summers as indicated by the ending ''b.'', while ''Dwb'' indicates a semi-Monsoon continental climate, monsoonal continental climate ...
