Cimarron Ridge
Cimarron Ridge is a ridge in the San Juan Mountains in southwestern Colorado. The ridge runs north-south and occupies parts of Gunnison, Montrose, Ouray, and Hinsdale counties. The ridge parallels U.S. Highway 550, and parts of the ridge can be seen from points along the highway. Prominent peaks Peaks along the ridge include Courthouse Mountain, elevation , and Chimney Rock, elevation . Chimney Rock is known for appearing in the 1969 western motion picture ''True Grit'' and is considered among the most difficult peaks to climb in Colorado. Geology The ridge is made up of green and gray tuff breccia Breccia () is a rock composed of large angular broken fragments of minerals or rocks cemented together by a fine-grained matrix. The word has its origins in the Italian language, in which it means "rubble".

San Juan Mountains
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] |
True Grit (1969 Film)
''True Grit'' is a 1969 American Western film directed by Henry Hathaway, starring John Wayne as U.S. Marshal Rooster Cogburn, Glen Campbell as La Boeuf and Kim Darby as Mattie Ross. It is the first film adaptation of Charles Portis' 1968 novel of the same name. The screenplay was written by Marguerite Roberts. Wayne won his only Oscar for his performance in the film and reprised his role for the 1975 sequel ''Rooster Cogburn''. Historians believe Cogburn was based on Deputy U.S. Marshal Heck Thomas, who brought in some of the toughest outlaws. The cast also features Robert Duvall, Dennis Hopper, Jeff Corey and Strother Martin. The title song, sung by Campbell, was also Oscar-nominated. ''True Grit'' was adapted again in 2010, starring Jeff Bridges, Matt Damon, Hailee Steinfeld, and Josh Brolin. Plot In 1880, Frank Ross, of Yell County, Arkansas, is murdered and robbed by his hired hand, Tom Chaney. Ross's young daughter, Mattie, travels to Fort Smith, where she hires a ...

Mountains Of Montrose 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 ...

Ridges Of Colorado
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for an extended distance. The sides of the ridge slope away from the narrow top on either side. The lines along the crest formed by the highest points, with the terrain dropping down on either side, are called the ridgelines. Ridges are usually termed hills or mountains as well, depending on size. Smaller ridges, especially those leaving a larger ridge, are often referred to as spurs. Types There are several main types of ridges: ;Dendritic ridge: In typical dissected plateau terrain, the stream drainage valleys will leave intervening ridges. These are by far the most common ridges. These ridges usually represent slightly more erosion resistant rock, but not always – they often remain because there were more joints where the valleys formed or other chance occurrences. This type of ridge is generally somewhat random in orientation, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cimarron Ridge Formation
The Cimarron Ridge Formation is a Mesozoic geologic formation in the United States. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.Weishampel, et al. (2004). "Dinosaur distribution."

Breccia
Breccia () is a rock composed of large angular broken fragments of minerals or rocks cemented together by a fine-grained matrix. The word has its origins in the Italian language, in which it means "rubble". A breccia may have a variety of different origins, as indicated by the named types including sedimentary breccia, tectonic breccia, igneous breccia, impact breccia, and hydrothermal breccia. A megabreccia is a breccia composed of very large rock fragments, sometimes kilometers across, which can be formed by landslides, impact events, or caldera collapse. Types Breccia is composed of coarse rock fragments held together by cement or a fine-grained matrix. Like conglomerate, breccia contains at least 30 percent of gravel-sized particles (particles over 2mm in size), but it is distinguished from conglomerate because the rock fragments have sharp edges that have not been worn down. These indicate that the gravel was deposited very close to its source area, since otherwise th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chimney Rock (Colorado)
Chimney Rock is an pillar located on the shared boundary of Hinsdale County with Ouray County, in southwest Colorado, United States. It is situated 10.5 miles east of the community of Ridgway, and immediately south of Owl Creek Pass, in the Uncompahgre Wilderness, on land managed by Uncompahgre National Forest. Owl Creek Pass separates Chimney Rock from Cimarron Ridge to the north. It is part of the San Juan Mountains which are a subset of the Rocky Mountains, and is situated west of the Continental Divide. Chimney Rock is the steepest point in Colorado with an average steepness of 61.4 degrees.John Fayhee (2012), ''The Colorado Mountain Companion: A Potpourri of Useful Miscellany from the Highest Parts of the Highest State'', West Margin Press, Topographic relief is significant as the east aspect rises above West Fork Cimarron River in one-half mile. Chimney Rock can be seen from Highway 550 near Ridgway. This feature's name was officially adopted by the United States B ...

Courthouse Mountain
Courthouse Mountain is a mountain summit located on the shared boundary of Hinsdale County with Ouray County, in southwest Colorado, United States. It is situated 10.5 miles east of the community of Ridgway, and south of Owl Creek Pass, in the Uncompahgre Wilderness, on land managed by Uncompahgre National Forest. It is part of the San Juan Mountains which are a subset of the Rocky Mountains, and is situated west of the Continental Divide.

Chimney Rock Cimarron Ridge Sunset
A chimney is an architectural ventilation structure made of masonry, clay or metal that isolates hot toxic exhaust gases or smoke produced by a boiler, stove, furnace, incinerator, or fireplace from human living areas. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or chimney effect. The space inside a chimney is called the ''flue''. Chimneys are adjacent to large industrial refineries, fossil fuel combustion facilities or part of buildings, steam locomotives and ships. In the United States, the term ''smokestack industry'' refers to the environmental impacts of burning fossil fuels by industrial society, including the electric industry during its earliest history. The term ''smokestack'' (colloquially, ''stack'') is also used when referring to locomotive chimneys or ship chimneys, and the term ''funnel'' can also be used. The height of a chimn ...
