Fourmile Canyon
Fourmile Canyon or Four Mile Canyon is a mountainous canyon in western Boulder County, Colorado that channels a stream known as Fourmile Creek or Four Mile Creek (this is not Fourmile Canyon Creek which runs a few miles north of Fourmile Creek).). The stream rises at on the southern slope of Niwot Mountain, before flowing east and south through the unincorporated communities of Sunset, Wallstreet, Salina and Crisman to the confluence with Boulder Creek at in Boulder Canyon, four miles west of the historic location of the Boulder Railroad Depot. The canyon and surrounding area were the site of an eponymous major wildfire in September 2010. Early history In 1859, gold was discovered in the Fourmile Canyon area, leading to early settlement. The 1872 discovery of tellurium reinvigorated local mining communities. Fourmile Canyon was the location of the first narrow-gauge railroad to connect Union Pacific's standard-gauge network to the mines and mountain communities near Ward, ...

Salina, Colorado
Salina is a former mining town in Boulder County, Colorado, United States approximately west of Boulder. Established in 1874, after Colorado's first gold discovery in 1859, Salina was founded by miners who migrated to Boulder from Salina, Kansas. It is located at the junction of Four Mile Canyon and Gold Run roads. The mining camp was originally accessible only by horseback or wagons pulled by mules but later became part of Colorado's Switzerland Trail when the Greeley, Salt Lake, & Pacific narrow gauge railroad was built in the early 1880s. Today, most of Salina's original structures still stand, including the one-room schoolhouse, Salina School, and church, the Little Church in the Pines, despite some impact from the Fourmile Canyon wildfire in 2010 and historic flooding during the 2013 Colorado floods The 2013 Colorado floods were a series of natural disasters occurring in the U.S. state of Colorado. Starting on September 11, 2013, a slow-moving cold front stalled ove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aqua (satellite)
Aqua (EOS PM-1) is a NASA scientific research satellite in orbit around the Earth, studying the precipitation, evaporation, and cycling of water. It is the second major component of the Earth Observing System (EOS) preceded by Terra (launched 1999) and followed by Aura (launched 2004). The name "Aqua" comes from the Latin word for water. The satellite was launched from Vandenberg Air Force Base on May 4, 2002, aboard a Delta II rocket. Aqua operated in a sun-synchronous orbit as the third in the satellite formation called the " A Train" with several other satellites (OCO-2, the Japanese GCOM W1, PARASOL, CALIPSO, CloudSat, and Aura) for most of its first 20 years; but in January 2022 Aqua left the A-Train (as CloudSat, CALIPSO and PARASOL had already done) when, due to its fuel limitations, it transitioned to a free-drift mode, wherein its equatorial crossing time is slowly drifting to later times, from its tightly controlled orbit. Mission Aqua is one of NASA's missions for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Pit
A fire pit or a fire hole can vary from a pit dug in the ground to an elaborate gas burning structure of stone, brick, and metal. The defining feature of fire pits is that they are designed to contain fire and prevent it from spreading. Some recent fire pits have a fire bowl that can be placed in the ground or on legs. Contemporary types Pre-made fire pits are the most common form of fire pits and can be purchased from a store. These are commonly made of pre cast concrete or metal or a combination of metal table and stone. They burn usually natural gas, propane (LP) or bio ethanol. Wood burning fire pits made of metal are also quite common but under increasing scrutiny due to fire bans and air particulate emissions. Natural gas and propane burners in these sort of pre fabricated vessels are certified under ANSI (American), CSA (Canadian) and CE (European) standards. Unregulated and uncertified fire pit burners are increasingly being scrutinized by regulatory authorities and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Infrared
Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700 nanometers (430 THz). Longer IR wavelengths (30 μm-100 μm) are sometimes included as part of the terahertz radiation range. Almost all black-body radiation from objects near room temperature is at infrared wavelengths. As a form of electromagnetic radiation, IR propagates energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires emit invisible heat; in 1681 the pioneering experimenter Edme Mariotte showed that glass, though transparent to sunlight, obstructed radiant heat. In 1800 the astronomer Sir William Herschel discovered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relative Humidity
Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point. The amount of water vapor needed to achieve saturation increases as the temperature increases. As the temperature of a parcel of air decreases it will eventually reach the saturation point without adding or losing water mass. The amount of water vapor contained within a parcel of air can vary significantly. For example, a parcel of air near saturation may contain 28 g of water per cubic metre of air at , but only 8 g of water per cubic metre of air at . Three primary measurements of humidity are widely employed: absolute, relative, and specific. Ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Front Range
The Front Range is a mountain range of the Southern Rocky Mountains of North America located in the central portion of the U.S. State of Colorado, and southeastern portion of the U.S. State of Wyoming. It is the first mountain range encountered as one goes westbound along the 40th parallel north across the Great Plains of North America. The Front Range runs north-south between Casper, Wyoming, and Pueblo, Colorado, and rises nearly 10,000 feet above the Great Plains. Longs Peak, Mount Evans, and Pikes Peak are its most prominent peaks, visible from the Interstate 25 corridor. The area is a popular destination for mountain biking, hiking, climbing, and camping during the warmer months and for skiing and snowboarding during winter. Millions of years ago, the present-day Front Range was home to ancient mountain ranges, deserts, beaches, and even oceans. The name "Front Range" is also applied to the Front Range Urban Corridor, the populated region of Colorado and Wyoming just ...
