The La Mesa Fire was a 1977 wildfire on the Pajarito Plateau of New Mexico, in the Southwestern United States.
The La Mesa Fire was a 1977 wildfire on the Pajarito Plateau of New Mexico, in the Southwestern United States.
The fire was human-caused (likely a spark from a motorcycle) on the afternoon of 16 June 1977, in Los Alamos County. [1] Before it was contained one week later, the fire burned 15,444 acres (62.5 km²) of Bandelier National Monument and part of the Los Alamos National Laboratory, where it reached K-site and S-site, two facilities used to fabricate and test chemical explosives. [2]
Resources deployed to contain the fire included 1370 personnel, 9 bulldozers, 23 ground engines, 5 air tankers and 5 helicopters. [3] One human life was lost when a firefighter suffered a massive heart attack while fleeing the first major blowup of the La Mesa Fire. A monument near the entrance to Bandelier National Monument honors his memory. [3] A group of 27 high-school students were rescued after becoming trapped in the backcountry of Bandelier National Monument.[ citation needed ]
The La Mesa fire burned around 60% of the drainage basin of Rio de Los Frijoles, a tributary of the Rio Grande, and increased awareness of the contribution of wildfire to severe erosion. The La Mesa fire was significant for stimulating scientific study of the effects of fire on ecosystems.[ citation needed ]
La Mesa Fire is one of several major wildfires in the recent history of the Pajarito Plateau:
White Rock is an unincorporated community and census-designated place (CDP) in Los Alamos County, New Mexico. It is one of two major population centers in the county; the other is Los Alamos. The population was 5,725 at the 2010 census. It is largely a bedroom community for employees of Los Alamos National Laboratory and their families. Access to White Rock from the town of Los Alamos and other cities and towns in New Mexico is via New Mexico State Road 4, which forms the northwestern boundary of the community. Administratively, White Rock is a neighborhood of Los Alamos; locals refer to Los Alamos as "the Townsite," or "the Hill".
Valles Caldera is a 13.7-mile (22.0 km) 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 11,253-foot (3,430 m) 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. Much of the caldera is within the Valles Caldera National Preserve, a unit of the National Park System. In 1975, Valles Caldera was designated as a National Natural Landmark by the National Park Service.
Bandelier National Monument is a 33,677-acre (13,629 ha) United States National Monument near Los Alamos in Sandoval and Los Alamos counties, New Mexico. The monument preserves the homes and territory of the Ancestral Puebloans of a later era in the Southwest. Most of the pueblo structures date to two eras, dating between 1150 and 1600 AD.
The Puye Cliff Dwellings are the ruins of an abandoned pueblo, located in Santa Clara Canyon on Santa Clara Pueblo land near Española, New Mexico. The site was declared a National Historic Landmark in 1966.
The Jemez Mountains are a group of mountains in Rio Arriba, Sandoval, and Los Alamos counties, New Mexico, United States.
The Pajarito Plateau is a volcanic plateau in north central New Mexico, United States. The plateau, part of the Jemez Mountains, is bounded on the west by the Sierra de los Valles, the range forming the east rim of the Valles Caldera, and on the east by the Puye escarpment, which rises about 300 to 400 feet above the Rio Grande valley about a mile west of the river. The Rio Grande passes through White Rock Canyon to the southeast, and the Caja del Rio across the river is sometimes regarded as part of the plateau. The plateau is occupied by several notable entities, including Bandelier National Monument, the town of Los Alamos and its remote suburb White Rock, and Los Alamos National Laboratory. Elevations range from about 5600 feet at the river to about 7800 feet where the plateau merges into the mountain range.
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 43,000-acre (170 km2) 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.
The Dome Fire was a destructive wildfire in the Jemez Mountains in the northern region of the U.S. state of New Mexico during the 1996 fire season. It has been described by forester Bill Armstrong as "a wakeup call that nobody woke up to", anomalous at the time but an indicator of future high-intensity fires that are becoming more common due to both local and global environmental changes.
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. 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.
The Santa Fe National Forest is a protected national forest in northern New Mexico in the Southwestern United States. It was established in 1915 and covers 1,558,452 acres (6,306.83 km2). Elevations range from 5,300 feet (1600 m) to 13,103 feet (4000 m) at the summit of Truchas Peak, located within the Pecos Wilderness. The Jemez, Coyote, and Cuba districts are located in the Jemez Mountains; the Pecos/Las Vegas district is located in the Sangre de Cristo Mountains; and the Española district is located in both mountain ranges. In descending order of land area the forest lies in parts of Rio Arriba, San Miguel, Sandoval, Santa Fe, Mora, and Los Alamos counties. Forest headquarters are located in the city of Santa Fe.
New Mexico State Road 4 (NM 4) is a 67.946-mile-long (109.348 km) state highway in Sandoval, Los Alamos, and Santa Fe counties in New Mexico, United States. It is significant as the main access route connecting the remote town of Los Alamos, Los Alamos National Laboratory, and Bandelier National Monument to other, more major highways in New Mexico.
New Mexico State Road 502 (NM 502) is a 18.301-mile-long (29.453 km) state highway in New Mexico, United States of America. It is notable as the main access route to Los Alamos National Laboratory (LANL), Bandelier National Monument, Valles Caldera National Preserve, Jemez Mountains, and town of Los Alamos.
Caja del Rio is a dissected plateau, of volcanic origin, which covers approximately 84,000 acres of land in northern Santa Fe County, New Mexico, United States. The region is also known as the Caja, Caja del Rio Plateau, and Cerros del Rio. The center of the area is approximately 15 miles (23 km) west of Santa Fe, New Mexico. Most of the Caja is owned by the United States Forest Service and managed by the Santa Fe National Forest. Access is through New Mexico Highway 599, Santa Fe County Road 62, and Forest Service Road 24.
A potrero is a long mesa that at one end slopes upward to higher terrain. This landform commonly occurs on the flanks of a mountain, as part of a dissected plateau.
Los Alamos is a town 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.
Cerro Grande is a 10,207-foot (3,111 m) summit on the rim of the Valles Caldera not far north of New Mexico State Road 4, the main highway through Los Alamos County. Like many mountains in the Jemez, Cerro Grande was mainly covered with coniferous forest, composed largely of ponderosa pine and aspen trees, with a characteristic rincon (meadow) on its slopes on and south of the summit.
The Las Conchas Fire was a large wildfire in the state of New Mexico, in the United States, in 2011. The fire started in Santa Fe National Forest and burned more than 150,000 acres, threatening Los Alamos National Laboratory and the town of Los Alamos. After five days of burning, it became the largest wildfire in New Mexico state history at the time. It was surpassed in 2012 by the much larger Whitewater-Baldy Complex Fire and in 2022 by the Calf Canyon/Hermits Peak Fire and the Black Fire making the Las Conchas Fire the fourth-largest fire in New Mexico's recorded history.
Buckman is a ghost town in Santa Fe County, New Mexico, United States of America, about 5 miles (8.0 km) south of San Ildefonso Pueblo, on the east bank of the Rio Grande in White Rock Canyon.
The Bandelier Tuff is a geologic formation exposed in and around the Jemez Mountains of northern New Mexico. It has a radiometric age of 1.85 to 1.25 million years, corresponding to the Pleistocene epoch. The tuff was erupted in a series of at least three caldera eruptions in the central Jemez Mountains.
The Tewa Group is a group of geologic formations exposed in and around the Jemez Mountains of northern New Mexico. Radiometric dating gives it an age of 1.85 million to 72 thousand years, corresponding to the Pleistocene epoch.
