Cerro Grande Fire
The Cerro Grande Fire was a disastrous forest fire in New Mexico, United States of America, that occurred in May 2000. The fire started as a controlled burn, and became uncontrolled owing to high winds and drought conditions. Over 400 families in the town of Los Alamos, New Mexico, lost their homes in the resulting fire. Structures at Los Alamos National Laboratory were also destroyed or damaged, although without loss or destruction of any of the special nuclear material housed there. No loss of human life occurred. The US General Accounting Office estimated total damages at $1 billion. Prelude Although wildfire is a natural part of the ecosystem of western forests, fire suppression began to be widespread in the late 19th century just as land-use patterns (e.g. intensive grazing) limited the cover that had formerly sustained and been sustained by low-intensity ground fires. High-density stands of small trees and thick underbrush permitted a natural periodic ground f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Los Alamos, New Mexico
Los Alamos is an census-designated place in Los Alamos County, New Mexico, United States, that is recognized as the development and creation place of the atomic bomb—the primary objective of the Manhattan Project by Los Alamos National Laboratory during World War II. The town is located on four mesas of the Pajarito Plateau, and had a population of about 13,200 as of 2020. It is the county seat and one of two population centers in the county known as census-designated places (CDPs); the other is White Rock. History The ruins of permanent Puebloan settlements, such as those located in nearby Bandelier National Monument and Tsankawi, and numerous other sites such as cliff dwellings indicate that the area has been inhabited during various eras since around 1150 AD. The first settlers on the plateau are thought to be Keres speaking Native Americans around the 10th century. Around 1300, Tewa settlers immigrated from the Four Corners Region and built large cities but were driven o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Canyon Fire
The Water Canyon Fire of 1954 was a wildfire in the eastern edge of the Jemez Mountains and the Santa Fe National Forest which burned approximately 3,000 to 6,000 acres (12−24 km²). The fire started on June 5, 1954, when the burning of trash and construction debris in upper Water Canyon got out of control.Burkhardt, Bernice (June 6, 1954) "Wind Drives Forest Fires Near Los Alamos: Officials Believe Blaze Is Checked, City in No Danger" ''The Albuquerque Journal'' page 1, headline & column 6, continued page 2, column 3 Winds of up to 45 mph (72 km/h) pushed the fire 4 miles (6 km) north before it was contained after several days of work by 1,000 firefighters and a favorable change in wind conditions. The fire was significant for being the first fire to require the evacuation of nearby Los Alamos, New Mexico. Although most sources list the Water Canyon Fire as occurring in 1954, one document from Los Alamos County (Multi-Hazard Mitigation Plan) lists the fire wit ...

Jemez Mountains
The Jemez Mountains are a group of mountains in Rio Arriba, Sandoval, and Los Alamos counties, New Mexico, United States. Numerous Puebloan Indian tribes have lived in the Jemez Mountains region since before the Spanish arrived in New Mexico. The Pueblo Indians of this region are the Towa-speaking Jemez people for which this mountain range is named, the Keres-speaking Keresan Indians, and the Tewa-speaking Tewa Indians. Tsąmpiye'ip'įn is the Tewa language name for the Jemez Mountains. The highest point in the range is Chicoma Mountain (also spelled as Tschicoma or Tchicoma) at an elevation of . The town of Los Alamos and the Los Alamos National Laboratory adjoin the eastern side of the range while the town of Jemez Springs is to the west.

New Mexico State Road 4
New Mexico State Road 4 (NM 4) is a state highway in Sandoval, Los Alamos, and Santa Fe counties in New Mexico, United States. It is significant as the main access route (in conjunction with NM 501 and NM 502) connecting the remote town of Los Alamos, Los Alamos National Laboratory, and Bandelier National Monument to other, more major highways in New Mexico. Route description NM 4's western terminus is in the small town of San Ysidro, at U.S Route 550. The route passes through Jemez Pueblo and Jemez Springs as it climbs steeply into the Jemez Mountains and Santa Fe National Forest, and skirts the southern boundary of Valles Caldera National Preserve. On the east side of the Jemez Mountains, it descends even more steeply, on a series of hairpin turns offering views into Frijoles Canyon in Bandelier National Monument, to a junction with NM 501 leading east into the town of Los Alamos.

Valles Caldera
Valles Caldera (or Jemez Caldera) is a wide volcanic caldera in the Jemez Mountains of northern New Mexico. Hot springs, streams, fumaroles, natural gas seeps and volcanic domes dot the caldera floor landscape. The highest point in the caldera is Redondo Peak, an resurgent lava dome located entirely within the caldera. Also within the caldera are several grass valleys, or ''valles'', the largest of which is Valle Grande ( ), the only one accessible by a paved road. In 1975, Valles Caldera was designated as a National Natural Landmark by the National Park Service with much of the caldera being within the Valles Caldera National Preserve, a unit of the National Park System. History Use of Valles Caldera dates back to the prehistoric times: spear points dating to 11,000 years ago have been discovered.Anscheutz, Kurt F. and Merlan, Thomas (2007)"More than a scenic mountain landscape: Valles Caldera National Preserve land use history" U.S. Department of Agriculture Rocky Mountain ...

Summit (topography)
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may also refer to the highest point along a line, trail, or route. The highest summit in the world is Mount Everest with a height of above sea level. The first official ascent was made by Tenzing Norgay and Sir Edmund Hillary ...

Firewood
Firewood is any wooden material that is gathered and used for fuel. Generally, firewood is not highly processed and is in some sort of recognizable log or branch form, compared to other forms of wood fuel like pellets or chips. Firewood can be seasoned and heat treated (dry) or unseasoned (fresh/wet). It is generally classified as hardwood or softwood. Firewood is a renewable resource. However, demand for this fuel can outpace its ability to regenerate on a local or regional level. Good forestry practices and improvements in devices that use firewood can improve local wood supplies. Moving firewood long distances can potentially transport diseases and invasive species. History For most of human history firewood was the main fuel, until the use of coal spread during the Industrial Revolution. As such, access to firewood was a valued resource, wood botes or the right to gather firewood being a significant aspect of many medieval leases. As late as 19th C America, Thoreau ...

Moisture Content
Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture), rock, ceramics, crops, or wood. Water content is used in a wide range of scientific and technical areas, and is expressed as a ratio, which can range from 0 (completely dry) to the value of the materials' porosity at saturation. It can be given on a volumetric or mass (gravimetric) basis. Definitions Volumetric water content, θ, is defined mathematically as: :\theta = \frac where V_w is the volume of water and V_\text = V_s + V_w + V_a is equal to the total volume of the wet material, i.e. of the sum of the volume of solid host material (e.g., soil particles, vegetation tissue) V_s, of water V_w, and of air V_a. Gravimetric water content is expressed by mass (weight) as follows: :u = \frac where m_w is the mass of water and m_s is the mass of the solids. For materials that change in volume with water content, such as coal, the gravimetric water content, ''u'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Firebreak
A firebreak or double track (also called a fire line, fuel break, fireroad and firetrail in Australia) is a gap in vegetation or other combustible material that acts as a barrier to slow or stop the progress of a bushfire or wildfire. A firebreak may occur naturally where there is a lack of vegetation or "fuel", such as a river, lake or canyon. Firebreaks may also be man-made, and many of these also serve as roads, such as a logging road, four-wheel drive trail, secondary road, or a highway. Overview In the construction of a firebreak, the primary goal is to remove deadwood and undergrowth down to mineral soil. Various methods may be used to accomplish this initially and to maintain this condition. Ideally, the firebreak will be constructed and maintained according to the established practices of sustainable forestry and fire protection engineering, also known as best management practices (BMP). The general goals are to maximize the effectiveness of the firebreak at slowing th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Park Service
The National Park Service (NPS) is an agency of the United States federal government within the U.S. Department of the Interior that manages all national parks, most national monuments, and other natural, historical, and recreational properties with various title designations. The U.S. Congress created the agency on August 25, 1916, through the National Park Service Organic Act. It is headquartered in Washington, D.C., within the main headquarters of the Department of the Interior.
