Red Mountain Pass (San Juan Mountains)
Red Mountain Pass elevation is a mountain pass in the San Juan Mountains of western Colorado in the United States. The pass straddles a divide that separates Ouray and San Juan counties. The pass is named for the nearby Red Mountain on the northeast side of the pass. The name is derived from the iron oxide laden rock that forms their slopes. The pass separates the Uncompahgre and Las Animas River watersheds, and also serves as a dividing point between the Uncompahgre and San Juan National Forests. The pass is traversed by the Million Dollar Highway, U.S. Highway 550 between Ouray and Silverton, which is part of the San Juan Skyway Scenic Byway. The pass is known for being treacherous in the wintertime due to the steep 8% grade and switchbacks on the north side facing Ouray, though the entire road is paved. Avalanches are frequent, and can block the highway for some time. The lower part of the pass towards Ouray is blasted into near-vertical cliffs of quartzite hundr ...

The Durango Herald
''The Durango Herald'' is a newspaper in Durango, Colorado. History The first edition of the ''Herald'' came out June 30, 1881. Two years later, the ''Herald'' merged with the ''Record'', which had started publishing in 1880, seven months before the ''Herald''. The modern ''Herald'' traces its roots to both papers but the current ''Herald'' nameplate cites 1881 as the paper's founding year. The paper was combined in 1952 after Arthur and Morley Cowles Ballantine purchased the ''Herald-Democrat'' and the ''News''. In 1960, the name was changed to ''The Durango Herald''. Arthur was co-editor and co-publisher of the paper from 1952 until 1975. Morley was also co-editor and co-publisher and took over as chairman and editor after Arthur's death. She served as editor until her death in 2009. Her son Richard Ballantine took over the role of publisher in 1980. He retired in 2013, and Douglas Bennett was installed as CEO of Ballantine Communications, Inc., the ''Herald'''s parent com ...

Landforms Of Ouray County, Colorado
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodi ...

San Juan Mountains (Colorado)
The San Juan Mountains is a high and rugged mountain range in the Rocky Mountains in southwestern Colorado and northwestern New Mexico. The area is highly mineralized (the Colorado Mineral Belt) and figured in the gold and silver mining industry of early Colorado. Major towns, all old mining camps, include Creede, Lake City, Silverton, Ouray, and Telluride. Large scale mining has ended in the region, although independent prospectors still work claims throughout the range. The last large-scale mines were the Sunnyside Mine near Silverton, which operated until late in the 20th century, and the Idarado Mine on Red Mountain Pass, which closed in the 1970s. Famous old San Juan mines include the Camp Bird and Smuggler Union mines, both located between Telluride and Ouray. The Summitville mine was the scene of a major environmental disaster in the 1990s when the liner of a cyanide-laced tailing pond began leaking heavily. Summitville is in the Summitville caldera, one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alpine Climate
Alpine climate is the typical climate for elevations above the tree line, where trees fail to grow due to cold. This climate is also referred to as a mountain climate or highland climate. Definition There are multiple definitions of alpine climate. In the Köppen climate classification, the alpine and mountain climates are part of group ''E'', along with the polar climate, where no month has a mean temperature higher than . According to the Holdridge life zone system, there are two mountain climates which prevent tree growth : a) the alpine climate, which occurs when the mean biotemperature of a location is between . The alpine climate in Holdridge system is roughly equivalent to the warmest tundra climates (ET) in the Köppen system. b) the alvar climate, the coldest mountain climate since the biotemperature is between 0 °C and 1.5 °C (biotemperature can never be below 0 °C). It corresponds more or less to the coldest tundra climates and to the ice cap cli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Subarctic Climate
The subarctic climate (also called subpolar climate, or boreal climate) is a continental 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°N to 70°N, poleward of the humid continental climates. Like other Class D climates, they are rare in the Southern Hemisphere, only found at some isolated highland elevations. 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 on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tailings
In mining, tailings or tails are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are different from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. Waste valorization is the evaluation of waste and residues from an economic process in order to determine their value in reuse or recycling, as what was gangue at the time of separation may increase with time or more sophisticated recovery processes. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining, which pulverizes the rock containing the ore and then relies on chemical reactions to concentrate the sought-after material. In the latter, the extraction of minerals from ore requires comminution, i.e., grinding the ore into fine partic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Idarado Mine
The Idarado Mine was a mining operation in the San Juan Mountains of Ouray County, Colorado near the now-ghost town of Guston, Colorado, Guston, producing primarily lead, zinc and silver along with small amounts of gold and copper. The mine is within the Gold mining in Colorado#Sneffels-Red Mountain-Telluride district, Sneffels-Red Mountain-Telluride mining district. The remains of the operation are visible from the Million Dollar Highway, north of Red Mountain Pass (San Juan Mountains), Red Mountain Pass, between Ouray, Colorado, Ouray and Silverton, Colorado. The tunnels of the Idarado extend some 5 miles (8 km) west under 13,000 foot (4,000 m) mountains to the Pandora Mill near Telluride, Colorado, Telluride, a trip of more than 60 miles (100 km) by highway. The mine was a consolidation of several previously inactive mines interconnected via the Treasury Tunnel. The "Treasury Tunnel Mining and Reduction Company" was created in 1896 by mine developer William Ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guston, Colorado
Guston is a silver mining ghost town in Ouray County, Colorado, United States, south of Ouray following the "Million Dollar Highway" (U.S. Route 550). Nestled in Champion Gulch, it is located near Red Mountain and the remnants of Red Mountain Town and Ironton. The Silverton Railroad ran from Guston in the Red Mountain Pass to Silverton in San Juan County. The silver mining camp was established in 1883. The Guston post office operated from January 26, 1892, until November 16, 1898. Description While there was initially talk of naming the settlement "Missouri City," the name of the first mine in the area was instead selected. The town was never formally instituted and construction of commercial and residential structures occurred in an ad hoc fashion. By July 2000, the remains of Guston were composed of several mining structures and a bridge that carried the Silverton Railroad through town. One entrance to the Idarado Mine, Treasury Tunnel, is still visible. The church a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
