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.

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 y ... [...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 ...

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] |
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 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 climate, mountains te ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface Runoff
Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to ''channel runoff'' (or ''stream flow''). It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is #Saturation excess overland flow, saturated by water to its full capacity, and the rain arrives #Infiltration excess overland flow, more quickly than the soil can absorb it. Surface runoff often occurs because wikt:impervious#Adjective, impervious areas (such as roofs and Road surface, pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or human-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of Soil erosion#Rainfall and runoff, soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. ...

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] |
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 ...

Caroline Bancroft
Caroline Bancroft (September 11, 1900 – October 5, 1985) was an American journalist. She is known for the books and booklets that she wrote about Colorado's history and its pioneers. In 1990, she was inducted into the Colorado Women's Hall of Fame. Early life Bancroft was born in Denver, Colorado, on September 11, 1900, to an established, "upper crust" family and was a third-generation Coloradan. Her parents were Ethel Force Norton, a socialite from Troy, New York, and George Jarvis Bancroft, a Coloradan who graduated in 1895 from Stanford University. He was in the school's first graduating class with future president Herbert Hoover. Dr. Frederick J. Bancroft, her grandfather, was a Colorado pioneer and surgeon. In 1879 he was co-founder and first president of the Colorado Historical Society, originally called the State Historical and National History Society of Colorado. He served as president for 17 years.

Avalanche
An avalanche is a rapid flow of snow down a Grade (slope), slope, such as a hill or mountain. Avalanches can be triggered spontaneously, by factors such as increased precipitation or snowpack weakening, or by external means such as humans, other 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, Mudflow, mudslides, Landslide#Debris landslide, rock slides, and serac collap ...

Pandora, Colorado
Pandora is an unincorporated community located east of Telluride in San Miguel County, Colorado San Miguel County is a county located in the U.S. state of Colorado. As of the 2020 census, the population was 8,072. The county seat is Telluride. The county is named for the San Miguel River. History San Miguel County was given the Spanis .... 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 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 i ... [...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 the 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 construc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
