Ajax Peak
Ajax Peak is a mountain summit located in San Miguel County of southwest Colorado, United States. It is situated on land managed by Uncompahgre National Forest, and is the iconic landmark visible three miles east of the community of Telluride. Ajax is set immediately south of Savage Basin and the ghost town of Tomboy, one mile southwest of Chicago Peak, and one mile west of Telluride Peak. It is also immediately northeast of Bridal Veil Falls, Colorado's highest waterfall at 365-feet high. It is part of the San Juan Mountains which are a subset of the Rocky Mountains. Topographic relief is significant as the west aspect rises above the box canyon in approximately one mile. The old mill town of Pandora at the base of Ajax Peak was hit by snow slides each winter, and one particularly bad event in 1884 came over the Ajax Mine and wrecked the mills.Caroline Bancroft, ''Unique Ghost Towns and Mountain Spots'', 1961, Johnson Publishing Company, , page 92.

Chicago Peak
Chicago Peak is a mountain summit located on the shared boundary of San Miguel County with Ouray County in southwest Colorado, United States. It is situated east of the community of Telluride, on land managed by Uncompahgre National Forest. It is part of the Sneffels Range which is a subset of the San Juan Mountains, which in turn are part of the Rocky Mountains. It is set above the ghost town of Tomboy, south of United States Mountain, and one mile northwest of Imogene Pass. Topographic relief is significant as the east aspect rises above Imogene Basin in approximately one mile, and the west aspect rises 2,000 feet above Savage Basin in less than one mile. Mining activity in the immediate area produced significant amounts of gold and silver. Climate According to the Köppen climate classification system, Chicago Peak is located in an alpine subarctic climate zone with cold, snowy winters, and cool to warm summers. Due to its altitude, it receives precipitation all yea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mill (grinding)
A mill is a device, often a structure, machine or kitchen appliance, that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind (windmill) or water (watermill). In modern era, they are usually powered by electricity. The grinding of solid materials occurs through mechanical forces that break up the structure by overcoming the interior bonding forces. After the grinding the state of the solid is changed: the grain size, the grain size disposition and the grain shape. Milling also refers to the process of breaking down, separating, sizing, or classifying aggregate material (e.g. mining ore). For instance rock crushing or grinding to produce uniform aggregate size for construction purp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 that closed down 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 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of San Miguel County, Colorado
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 terrain and ...

San Miguel River (Colorado)
The San Miguel River is a tributary of the Dolores River, approximately long, in southwestern Colorado in the United States. It rises in the San Juan Mountains southeast of Telluride and flows northwest, along the southern slope of the Uncompahgre Plateau, past the towns of Placerville and Nucla and joins the Dolores in western Montrose County approximately 15 miles (24 km) east of the state line with Utah. Geography and protected areas The San Miguel is more or less free-flowing; however, diversion dams dot the river and alter flows. In some parts it is however one of the few remaining naturally functioning rivers of the West. The San Miguel varies in gradient, from extremely steep in its upper reaches (forming a shallow, rocky, unnavigable stream) to more mellow in the lower sections ( of drop, which offers the whitewater boater a variety of runs all within the class II+--III range). All told, the San Miguel drops over from an alpine ecosystem to the desert. The ave ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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] |

Avalanche
An avalanche is a rapid flow of snow down a slope, such as a hill or mountain. Avalanches can be set off spontaneously, by such factors as increased precipitation or snowpack weakening, or by external means such as humans, animals, and earthquakes. Primarily composed of flowing snow and air, large avalanches have the capability to capture and move ice, rocks, and trees. Avalanches occur in two general forms, or combinations thereof: slab avalanches made of tightly packed snow, triggered by a collapse of an underlying weak snow layer, and loose snow avalanches made of looser snow. After being set off, avalanches usually accelerate rapidly and grow in mass and volume as they capture more snow. If an avalanche moves fast enough, some of the snow may mix with the air, forming a powder snow avalanche. Though they appear to share similarities, avalanches are distinct from slush flows, mudslides, rock slides, and serac collapses. They are also different from large scale movement ...

Pandora, Colorado
Pandora is an unincorporated community located east of Telluride in San Miguel County, Colorado. Pandora was founded in the 1880s as a mill town, serving as the site for mills of the Smuggler-Union, Tomboy, and Sheridan mines. The Rio Grande Southern The Rio Grande Southern Railroad (reporting mark RGS, also referred to as "The Southern") was a 3 ft (914 mm) narrow-gauge railroad which ran in the southwestern region of the US state of Colorado, from the towns of Durango to Ridgway, ... railroad's Telluride branch terminated at the mills in Pandora. Milling largely ended during World War 2 (when by government order all precious metals mines were closed), by which time the townsite was largely covered in mill tailings. The Pandora Mill, previously one of the Smuggler Union mills, still stands at Pandora. The mill was constructed in 1920 to replace the previous Smuggler mill that had burned down. The mill had various periods of activity but was unusual in that it wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
