Timpanogos Glacier
Timpanogos Glacier is a rock glacier located on Mount Timpanogos in the Wasatch Range within the Mount Timpanogos Wilderness (in the Uinta National Forest, Uinta-Wasatch-Cache National Forest) in northeastern Utah County, Utah, Utah County, Utah, United States, and is the last known glacier in Utah. Description The glacier is situated on the north slope of Mount Timpanogos (). The best evidence indicates that the Timpanogos Glacier was once a "true" glacier with crevasses present in the early 20th century, but that the surface portion was lost during the dust bowl drought of the 1930s and reduced to a permanent snowfield. The glacier is considered to be a rock glacier, since the remaining ice is buried in the talus. However, in 1994 the rocks parted, revealing a crevasse or meltwater channel in the buried ice. One witness described it as being " thick at least." Another crevasse reportedly opened up in the late 1990s or early 2000s. One witness threw a stone in and from the fa ...

Emerald Lake (Utah)
Emerald Lake is a small proglacial lake near the summit of Mount Timpanogos in the middle of the Mount Timpanogos Wilderness in the Wasatch Range in northeastern Utah County, Utah, Utah County, Utah, United States. Description The lake is northeast of the summit of Mount Timpanogos, at the base of the almost vertical northeast face of the mountain, with an elevation of . The now mostly vanished and completely buried Timpanogos Glacier left behind a terminal moraine which now impounds the lake. The runoff from the rock glacier feeds the lake and colors it blue. The lake is accessible by hiking, the Mount Timpanogos Trail (also known as the Aspen Grove Trail) from Aspen Grove, Utah, Aspen Grove being the fastest way to reach it. The lake is from the trailhead, or about two-thirds of the way up to the summit. During summer weekends the Timpanogos Emergency Response Team (TERT) stations volunteers at a camp near Emerald Lake to assist with emergency incidents that frequently occur ...

Dust Bowl
The Dust Bowl was a period of severe dust storms that greatly damaged the ecology and agriculture of the American and Canadian prairies during the 1930s. The phenomenon was caused by a combination of both natural factors (severe drought) and manmade factors (a failure to apply dryland farming methods to prevent aeolian processes, wind erosion, most notably the destruction of the natural topsoil by settlers in the region). The drought came in three waves: 1934–35 North American drought, 1934, 1936, and 1939–1940, but some regions of the High Plains (United States), High Plains experienced drought conditions for as many as eight years. The Dust Bowl has been the subject of many cultural works, notably the novel ''The Grapes of Wrath'' (1939) by John Steinbeck, the folk music of Woody Guthrie, and photographs depicting the conditions of migrants by Dorothea Lange, particularly the ''Migrant Mother'', taken in 1936.

Glaciers Of Utah
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between latitudes 35°N and 35°S, glaciers occur only in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retreat Of Glaciers Since 1850
The retreat of glaciers since 1850 affects the availability of fresh water for irrigation and domestic use, mountain recreation, animals and plants that depend on glacier-melt, and, in the longer term, the level of the oceans. Deglaciation occurs naturally at the end of ice ages, but glaciologists find the current glacier retreat is accelerated by the measured increase of atmospheric greenhouse gases—an effect of climate change. Mid-latitude mountain ranges such as the Himalayas, Rockies, Alps, Cascades, Southern Alps, and the southern Andes, as well as isolated tropical summits such as Mount Kilimanjaro in Africa, are showing some of the largest proportionate glacial losses. Excluding peripheral glaciers of ice sheets, the total cumulated global glacial losses over the 26 year period from 1993–2018 were likely 5500 gigatons, or 210 gigatons per yr.Fox-Kemper, B., H.T.

Moraine
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Proven ...

Proglacial Lake
In geology, a proglacial lake is a lake formed either by the damming action of a moraine during the retreat of a melting glacier, a glacial ice dam, or by meltwater trapped against an ice sheet due to isostatic depression of the crust around the ice. At the end of the last ice age about 10,000 years ago, large proglacial lakes were a widespread feature in the northern hemisphere. Moraine-dammed The receding glaciers of the tropical Andes have formed a number of proglacial lakes, especially in the Cordillera Blanca of Peru, where 70% of all tropical glaciers are. Several such lakes have formed rapidly during the 20th century. These lakes may burst, creating a hazard for zones below. Many natural dams (usually moraines) containing the lake water have been reinforced with safety dams. Some 34 such dams have been built in the Cordillera Blanca to contain proglacial lakes. Several proglacial lakes have also formed in recent decades at the end of glaciers on the eastern side of Ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Meltwater Channel
A meltwater channel (or sometimes a glacial meltwater channel) is a channel cut into ice, bedrock or unconsolidated deposits by the flow of water derived from the melting of a glacier or ice-sheet. The channel may form on the surface of, within, beneath, along the margins of or downstream from the ice mass. Accordingly it would be referred to as supraglacial, englacial, subglacial, lateral (or ice-marginal) or proglacial. Different forms of subglacial channel are described in glaciological literature including Nye or N-channels, Röthlisberger or R-channels and Hooke or H-channels. Tunnel valley is a related term descriptive of subglacial channels. Some examples of tunnel valleys in northwest England have also been described as iceways. The depositional landforms known as kames and eskers may often be found in association with meltwater channels. An urstromtal is a proglacial or ice-marginal channel common in Germany and Poland formed during various of the Pleistocene glaciat ...

Emerald Lake From Above
Emerald is a gemstone and a variety of the mineral beryl (Be3Al2(SiO3)6) colored green by trace amounts of chromium or sometimes vanadium.Hurlbut, Cornelius S. Jr. and Kammerling, Robert C. (1991) ''Gemology'', John Wiley & Sons, New York, p. 203, . Beryl has a hardness of 7.5–8 on the Mohs scale. Most emeralds are highly included, so their toughness (resistance to breakage) is classified as generally poor. Emerald is a cyclosilicate. Etymology The word "emerald" is derived (via fro, esmeraude and enm, emeraude), from Vulgar Latin: ''esmaralda''/''esmaraldus'', a variant of Latin ''smaragdus'', which was a via grc, σμάραγδος (smáragdos; "green gem") from a Semitic language. According to Webster's Dictionary the term emerald was first used in the 14th century. Properties determining value Emeralds, like all colored gemstones, are graded using four basic parameters–the four ''C''s of connoisseurship: ''color'', ''clarity,'' ''cut'' and ''carat weight''.
