City Of Rocks National Reserve
The City of Rocks National Reserve, also known as the Silent City of Rocks, is a United States National Reserve and state park in south-central Idaho, approximately north of the border with Utah. It is widely known for its enormous granite rock formations and excellent rock climbing. The rock spires in the City of Rocks and adjacent Castle Rocks State Park are largely composed of granitic rock of the Oligocene Almo pluton and Archean Green Creek Complex. City of Rocks is also a popular rock climbing area, with over 1,000 traditional and bolt-protected routes. In the 1980s, it was home to some of the most difficult routes in the country, mostly developed by Idaho climber Tony Yaniro. Climbers in the region refer to the area as simply "The City". During the 1840s and 1850s, wagon trains on the California Trail left the Raft River valley and traveled through the area and over Granite Pass into Nevada. Names or initials of emigrants written in axle grease are still visible on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
City Of Rocks State Park
City of Rocks State Park is a state park in New Mexico, consisting of large sculptured rock formations in the shape of pinnacles or boulders rising as high as . Geology The bedrock forming City of Rocks was created 34.9 million years ago by a volcanic eruption. Then over millions of years, erosion sculpted the rock formations seen today. The eruption was from the Emory Caldera, centered near Hillsboro Peak at the southern end of the Black Range. The eruption was estimated to be a VEI 8 eruption, and it emplaced the Kneeling Nun Tuff, a tuff bed covering an area of , which makes up the bedrock of the park. History The Mimbreno Indians settled in the area from 750 to 1250 AD. Pottery, arrowheads, and other artifacts show evidence of prehistoric Indians in the area. Indian wells, or conical holes, are found in the rocks where water would be allowed to collect. Chapter 110 of the 1953 Laws of New Mexico created City of Rocks State Park on March 20, 1953. This legislation pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Creek Complex
Green is the color between cyan and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content. During post-classical and early modern Europe, green was the color commonly associated with wealth, merchants, bankers, and the gentry, while red ...
