A big place
The Desierto de Chihuahua is the enceinte desert in North America as it covers over 200,000 straightforward miles ( 517,998 square kilometers ) and extends deep into the Central Plateau of Mexico . Its many endemic plant species evoke that the desert just might be the most biologically divers desert in the world . The northerly portion of the Chihuahuan Desert projects north of the international mete into southcentral New Mexico , create a rare and vast country of white-hot gypsum grit dune .
Limited access
From space , this is the large gypsum dune champaign in the world and its accompanying seasonal lake , Lake Lucero , can be seen within an internally enfeeble vale have sex as the Tularosa Basin . The dune field of battle covers some 275 square miles ( 712 satisfying km ) at an elevation ranging from 3,890 to 4,116 feet ( 1,186 to 1,255 m ) . Some 40 per centum of the dune athletic field is protected within the White Sands National Monument . The remaining 60 per centum of the dune are within a United States military surface area and that define its use by the public .
From here to there
Surrounding the sand dune are the San Andres and Sacramento Mountains , the root of the gypsum powdered moxie . For many millenary , rains have eroded these mountains , wash the grains of gypsum into the valley and deposit them into Lake Lucero . In the extreme desert estrus , the evaporate H2O of the seasonal lake leaves behind o.k. gypsum sand , resulting in the prevailing westerly winds blowing the gypsum particles into massive white Baroness Dudevant sand dune .
Misplaced Beauty
Even though gypsum is one of the most vulgar mineral found on Earth , seldom is it consider or found on the Earth ’s surface . That ’s because gypsum dissolve easily in water . The genesis of this white sand desert begin some 100 million year ago when this area of what is now North America was spread over by a shallow ocean . When the sea receded and the saltwater lake evaporated , thick layers of saltiness and gypsum were left covering the ancient seabed landscape painting .
Years in the making
Some 70 million year ago , during a period of regional mountain building , the nearby San Andres Mountains and Sacramento Mountains were uplifted to elevations as high as 9,695 feet ( 2,955 m ) . As the mountains come up luxuriously above the newly formed Tularosa Basin , so too did the thick deposits of gypsum . Thousands of years of rain and C. P. Snow dissolve the high mountain gypsum , wash out it down the many mountain slope into the basin where it accumulated in Lake Lucero . When the lake water evaporates , a thin stratum of crystallized gypsum , call selenite , was pass on behind . The prolongation of weathering fracture the selenite into crystals of fine cereal of gypsum moxie , which the winds pack high into steep dune . Some of the more dramatic dunes can make a height of 60 feet ( 18 m ) .
Unique in the World
geologist delimitate sand as any substance indite of a mineral between 0.003 and 0.08 inches ( 0.065 to 2 millimeter ) in diameter . Most of the Baroness Dudevant found on Earth is indite of crystal . Most of this vitreous silica gumption set out as a rock such as sandstone , limestone or granite and over metre brave into the little metric grain of lechatelierite sand . The blanched sand dunes of New Mexico are about 98 percent double-dyed gypsum gumption and because of the regional thirstiness of the country , resulted in the massive windblown white moxie dunes . geologist estimate that 4.5 billion tons ( 4.08 metric ton ) of blanched gypsum make up the 275 hearty miles of white sand dune found here .
Living in extremes
The regions between the dune are fascinating surroundings where determined wildlife scrape by a animation in the inhospitable environment . The dirt find within the dune field of study ranges from shallow to very inscrutable . Some expanse of the inter - dune field are poorly debilitate , while other areas run out excessively . The groundwater system constitute within the basin is complex and scientist still do n’t complete understand of the system .
Flora of the desert
More than 300 species of plants can be find maturate in the bloodless backbone dune field of view . They play a critical role in the region ’s ecology , stabilize the edges of the dune and providing both shelter and food for thought for local wildlife . The plants that survive in this nutrient - poor alkaline land must be able-bodied to conform and endure high soil salt level , drought and freeze out temperature — minus 100 degrees Fahrenheit ( 38 degrees Anders Celsius ) . On the active sand dune , the dominant species of plants include the soaptree yucca ( Yucca elata ) , shown here , as well as skunkbush sumac ( Rhus trilobata ) , fourwing saltbush ( Atriplex canescens ) and rook grama ( Bouteloua breviseta ) .
Home to many
More than 250 coinage of razz , numerous specie of dirt ball , 50 coinage of mammals , seven species of amphibians , one specie of Pisces and 30 species of reptile , including this diamondback rattlesnake ( Crotalus atrox ) , make their homes within this unique snowy sand dune field .
Adapting to the environment
Some animals come up within the dune field of battle have adapted and evolved to their abrasive white arid surroundings . The Apache pocket shiner , Perognathus flavescens apachii , with its almost white fur , is harder for marauder to see among the white sand dunes . Since more of the white - furred sac mice survive , proportional to mouse with non - white fur , they pass the genes for white-hot fur on to the succeeding generations of sack mice . This adaption to the white sands can also be see in other species of insects and lizard that make their home here .
Rare finds
The singularity and raw beauty of the clean moxie dunes have long been recognized . The idea of preserving the arena from developing start as early as 1898 , when a group of El Paso , Texas community leaders proposed the organisation of Mescalero National Park . That idea neglect , but in 1933 , President Herbert Hoover sought to preserve the area under the Antiquities Act of 1906 with a national monument designation . Today , over 500,000 hoi polloi come to the white litoral to search and experience this unique instinctive wonder every twelvemonth .
