El Pinacate y Gran Desierto de Altar Biosphere Reserve (Spanish : Reserva de la Biosfera El Pinacate y Gran Desierto de Altar) is a biosphere reserve and UNESCO World Heritage Site managed by the Federal government of Mexico, specifically by Secretariat of the Environment and Natural Resources, in collaboration with state government of Sonora and the Tohono O'odham.
It is in the Sonoran Desert in northwest Mexico, east of Gulf of California, in the eastern part Gran Desierto de Altar, just below the border of Arizona, United States and north of the city of Puerto Peñasco. It is one of the most significant visible landforms in North America seen from space. A volcanic system, known as Santa Clara is the main part of the landscape, including three peaks; Pinacate, Carnegie and Medio.
In the area there are over 540 species of plants, 40 species of mammals, 200 of birds, 40 of reptiles, also amphibians and freshwater fishes.There are threatened endemic species as sonoran pronghorn, bighorn sheep, gila monster and desert tortoise.
The biosphere reserve covers an area of 2,695.05 square kilometres (1,040.56 sq mi) making up about half of the World Heritage site. The extent of the World Heritage site is 7,146 km², greater than that of the states of Aguascalientes, Colima, Morelos and Tlaxcala separated.
El Pinacate y Gran Desierto de Altar Biosphere Reserve is known for its unique physical and biological characteristics, by the presence of a volcanic shield, and by the extensive areas of active dunes that surround it, and the greatest concentration of Maar craters. The Pinacate Mountains range has orogenic features of high interest, products of volcanic eruptions that accumulated lava in compact rocks, sand and volcanic ashes that formed colors of special beauty, and craters such as El Elegante, Cerro Colorado, MacDougal, and Sykes.
The Pinacate Peaks (Picos del Pinacate), a group of volcanic peaks and cinder cones, are located in the Reserve north of Puerto Peñasco. The highest peak is Cerro del Pinacate (Santa Clara volcano), with an elevation of 3,904 feet (1,190 m). Pinacate comes from Náhuatl language word pinacatl, for the Pinacate beetle, a stink beetle endemic to the Sonoran Desert.
The Pinacate Peaks volcanoes have erupted sporadically for about 4 million years. The most recent activity was about 11 000 years ago.
NASA sent astronauts to the Gran Desierto de Altar from 1965 to 1970, to train for walking on the moon, due to the similarities of the terrain to the lunar surface.
The first inhabitants are known as San Dieguito people, they were hunter-gatherer who lived off the land, moving from the mountains to the sea of Gulf of California looking for food. The early stages of occupation seem to have ended at the beginning of ice age about 20 thousand years ago, when drought forced people to leave the mountain range.
A second stage of occupation by San Dieguito people began in the late glacial period. This group returned to the mountains and lived as their ancestors had. Tinajas must have been a reliable source of water during this time. The second stage of occupation ended with the arrival of an antipyretic period 9000 years ago, which again forced the people to leave the territory.
The most recent indigenous inhabitants of the Pinacate and Gran Desierto de Altar are the Pinacateño band of the Hia C-ed O'odham. Like the prehistoric San Dieguito culture, the Pinacateños roamed the Pinacate all the way to the sea in search of food, concentrating their camps near the tinajas. During these voyages, they left signs of their presence; one example of this is the network of paths that go from tinaja to tinaja, as well as the stone tools and potsherds found near these water sources.
There are few records of those who were the first explorers in this area. Possibly the first white man to see the mountain now known as Sierra Pinacate was the explorer Melchior Díaz on 1540. Subsequently, on 1698 the priest Eusebio Kino, founder of Mission San Xavier del Bac in southern Tucson, Arizona, visited the site and returned on several occasions, he and his group climbed to the top of El Pinacate, which named Santa Clara Hill.
Before 1956, few scientists and explorers had been in El Pinacate y Gran Desierto de Altar, the most famous, the group MacDougal, Hornaday and Sykes who explored the western part of the mountain on 1907.
The Sonoran Desert is a North American desert which covers large parts of the Southwestern United States in Arizona and California and of Northwestern Mexico in Sonora, Baja California, and Baja California Sur. It is the hottest desert in Mexico. It has an area of 260,000 square kilometers (100,000 sq mi). The western portion of the United States–Mexico border passes through the Sonoran Desert.
Sonoyta, Sonora is a town in the northern Mexican state of Sonora. It stands on the U.S.-Mexico border, facing Lukeville, Arizona, in the United States. It is the municipal seat of the municipality of Plutarco Elías Calles.
The Yuma Desert is a lower-elevation section of the Sonoran Desert in the southwestern United States and the northwest of Mexico. It lies in the Salton basin. The desert contains areas of sparse vegetation and has notable areas of sand dunes. With an average rainfall less than 8 inches (200 mm) each year, this is among the harshest deserts in North America. Human presence is sparse throughout, the largest city being Yuma, Arizona, on the Colorado River and the border of California.
Federal Highway 8 is a free part of the federal highways corridors in Sonora. It is connected to the roadway that transitions from the border post at Lukeville, Arizona where it connects with Arizona State Route 85, proceeds south through Puerto Peñasco with Sonoyta, Sonora, and intersects with Fed. 2. It continues through the El Pinacate and Gran Desierto de Altar Biosphere Reserve until ending at Puerto Peñasco, a length of 100 km (62 mi).
The Lechuguilla Desert is a small desert located in southwestern Arizona near the U.S.-Mexico border. It is considered to be part of the Lower Colorado Valley region of the Sonoran Desert. It lies in a north-south direction between the Gila Mountains and the Cabeza Prieta Mountains, and almost entirely in the Barry M. Goldwater Air Force Range. The desert is named after the Lechuguilla plant, known scientifically as Agave lecheguilla which according to the Wikipedia entry for that occurs exclusively in the Chihuahuan desert many hundreds of miles to the east. The desert is also on the north border of the Gran Desierto de Altar of Sonora, Mexico.
The Sierra de Los Tuxtlas are a volcanic belt and mountain range along the southeastern Veracruz Gulf coast in Eastern Mexico. The Los Tuxtlas Biosphere Reserve includes the coastal and higher elevations of the Sierra de Los Tuxtlas.
The Gran Desierto de Altar is one of the major sub-ecoregions of the Sonoran Desert, located in the State of Sonora, in northwest Mexico. It includes the only active erg dune region in North America. The desert extends across much of the northern border of the Gulf of California, spanning more than 100 kilometres (62 mi) east to west and over 50 kilometres (31 mi) north to south. It constitutes the largest continuous wilderness area within the Sonoran Desert.
The Sonoran green toad is a species of toad in the family Bufonidae. It is found in northern Mexico and the southwestern United States.
The Tinajas Altas Mountains are an extremely arid northwest-southeast trending mountain range in southern Yuma County, Arizona, approximately 35 mi southeast of Yuma, Arizona. The southern end of the range extends approximately one mile into the northwestern Mexican state of Sonora on the northern perimeter of the Gran Desierto de Altar. The range is about 22 mi in length and about 4 mi wide at its widest point. The highpoint of the range is unnamed and is 2,766 feet above sea level and is located at 32°16'26"N, 114°02'48"W. Aside from the portion of the range in Mexico, the entirety of the range lies within the Barry M. Goldwater Air Force Range. They lie at the heart of the traditional homeland of the Hia C-eḍ O'odham people.
The Cabeza Prieta Mountains are a mountain range in the northwestern Sonoran Desert of southwest Arizona. It is located in southern Yuma County, Arizona.
Pinacate may refer to:
The Sierra Pinta or Sierra Pintas are a narrow remote block faulted northwest-southeast trending mountain range, about 22 miles (35 km) long located in southwestern Arizona in the arid northwestern Sonoran Desert, just north of the Pinacate Reserve of northern Sonora, Mexico. The mountains derive their name from visitor descriptions of its multicolored hues when viewed at sunrise and sunset.
The Pinacate Peaks are a group of volcanic peaks and cinder cones located mostly in the Mexican state of Sonora along the international border adjacent to the U.S. state of Arizona, surrounded by the vast sand dune field of the Gran Desierto de Altar, at the desert's southeast.
The Monarch Butterfly Biosphere Reserve is a World Heritage Site containing most of the over-wintering sites of the eastern population of the monarch butterfly. The reserve is located in the Trans-Mexican Volcanic Belt pine-oak forests ecoregion on the border of Michoacán and State of Mexico, 100 km, northwest of Mexico City. Millions of butterflies arrive in the reserve annually. Butterflies only inhabit a fraction of the 56,000 hectares of the reserve from October–March. The biosphere’s mission is to protect the butterfly species and its habitat.
Puerto Peñasco Municipality is a municipality in Sonora in north-western Mexico. As of 2015, the municipality had a total population of 62,177 inhabitants. The only locality with a significant population is the municipal seat, also named Puerto Peñasco, which contains almost 99% of the municipality's population.
Tinaja is a term originating in the American Southwest for surface pockets (depressions) formed in bedrock that occur below waterfalls, are carved out by spring flow or seepage, or are caused by sand and gravel scouring in intermittent streams (arroyos). Tinajas are an important source of surface water storage in arid environments.
Alto Golfo de California Biosphere Reserve is a UNESCO Biosphere Reserve located in the state of Sonora in extreme northwestern Mexico. The 1,652,110 hectares (6,378.8 sq mi) reserve comprises the El Pinacate y Gran Desierto reserve and the Bahia Adair on the Gulf of California border. Geological volcanic formations with craters, dunes, oasis and beaches, and the diversity of plant associations determine its special landscape. The reserve was established in 1993 by the President of Mexico as Reserva de la Biosfera del Alto Golfo de California y Delta del Río Colorado and extended in 1995.
The Volcán Tacaná Biosphere Reserve is a UNESCO Biosphere Reserve at the Tacaná Volcano in Chiapas, Mexico, on the border with Guatemala. The volcano is part of the Central America Volcanic Arc. The 6,378 hectares (24.63 sq mi) reserve contains fragile ecosystems very rich in wild flora and fauna species of cultural, scientific, economic and biological relevance. Its rich biodiversity and high endemism are found particularly in the high mountain ecosystem and landscapes and in the volcanic edifice which presents geophysical features of great scientific and aesthetic value. Average annual rainfall can amount to 2,000–5,000 millimetres (79–197 in), as in the case of Soconusco.
