Desert exploration is the deliberate and scientific exploration of deserts, the arid regions of the earth. It is only incidentally concerned with the culture and livelihood of native desert dwellers. People have struggled to live in deserts and the surrounding semi-arid lands for millennia. Nomads have moved their flocks and herds to wherever grazing is available, and oases have provided opportunities for a more settled way of life. Many, such as the Bushmen in the Kalahari, the Aborigines in Australia and various Indigenous peoples of the Americas, were originally hunter-gatherers. Many trade routes have been forged across deserts, especially across the Sahara Desert, and traditionally were used by caravans of camels carrying salt, gold, ivory and other goods. Large numbers of slaves were also taken northwards across the Sahara. Today, some mineral extraction also takes place in deserts, and the uninterrupted sunlight gives potential for the capture of large quantities of solar energy.
Many people think of deserts as consisting of extensive areas of billowing sand dunes because that is the way they are often depicted on TV and in films, [1] but deserts do not always look like this. [2] Across the world, around 20% of desert is sand, varying from only 2% in North America to 30% in Australia and over 45% in Central Asia. [3] Where sand does occur, it is usually in large quantities in the form of sand sheets or extensive areas of dunes. [3] The following sections list deserts around the world, and their explorers. Expeditions are listed by their leaders; details of other expedition members may be found via the links.
Before the European exploration of North America, tribes of Native Americans, such as the Mohave (in the Mojave desert), the Chemehuevi (in the Great Basin desert), and the Quechan (in the Colorado desert) were hunter-gatherers living in the California deserts. [11] European explorers started exploring the deserts beginning in the 18th century. Francisco Garcés, a Franciscan friar, was the first explorer of the Colorado and Mojave deserts in 1776. [12] Garcés recorded information about the original inhabitants of the deserts.
Later, as American interests expanded into California, American explorers started probing the California deserts. Jedediah Smith travelled through the Great Basin and Mojave deserts in 1826, finally reaching the San Gabriel Mission. [13] [14] John C. Frémont explored the Great Basin, proving that water did not flow out of it to the ocean, and provided maps that the forty-niners used to get to California. [15]
The Simpson Desert is a large area of dry, red sandy plain and dunes in the Northern Territory, South Australia and Queensland in central Australia. It is the fourth-largest Australian desert, with an area of 176,500 km2 (68,100 sq mi).
The Mojave Desert is a desert in the rain shadow of the southern Sierra Nevada mountains and Transverse Ranges in the Southwestern United States. Named for the indigenous Mohave people, it is located primarily in southeastern California and southwestern Nevada, with small portions extending into Arizona and Utah.
The Desert of Hami is a section of the Gobi Desert in Xinjiang, China that occupies the space between the Tian Shan system on the north and the Nan-shan Mountains on the south, and is connected on the west with the Desert of Lop.
Francisco Hermenegildo Tomás GarcésO.F.M. was a Spanish Franciscan friar who served as a missionary and explorer in the colonial Viceroyalty of New Spain. He explored much of the southwestern region of North America, including present day Sonora and Baja California in Mexico, and the U.S. states of Arizona and California. He was killed along with his companion friars during an uprising by the Native American population, and they have been declared martyrs for the faith by the Catholic Church. The cause for his canonization was opened by the Church.
The Old Spanish Trail is a historical trade route that connected the northern New Mexico settlements of Santa Fe, New Mexico with those of Los Angeles, California and southern California. Approximately 700 mi (1,100 km) long, the trail ran through areas of high mountains, arid deserts, and deep canyons. It is considered one of the most arduous of all trade routes ever established in the United States. Explored, in part, by Spanish explorers as early as the late 16th century, the trail was extensively used by traders with pack trains from about 1830 until the mid-1850s. The area was part of Mexico from Mexican independence in 1821 to the Mexican Cession to the United States in 1848.
A desert pavement, also called reg, serir, gibber, or saï is a desert surface covered with closely packed, interlocking angular or rounded rock fragments of pebble and cobble size. They typically top alluvial fans. Desert varnish collects on the exposed surface rocks over time.
The Strzelecki Desert is located in the Far North Region of South Australia, South West Queensland and western New South Wales. It is positioned in the northeast of the Lake Eyre Basin, and north of the Flinders Ranges. Two other deserts occupy the Lake Eyre Basin—the Tirari Desert and the Simpson Desert.
The deserts of Australia or the Australian deserts cover about 1,371,000 km2 (529,000 sq mi), or 18% of the Australian mainland, but about 35% of the Australian continent receives so little rain, it is practically desert. Collectively known as the Great Australian desert, they are primarily distributed throughout the Western Plateau and interior lowlands of the country, covering areas from South West Queensland, Far West region of New South Wales, Sunraysia in Victoria and Spencer Gulf in South Australia to the Barkly Tableland in Northern Territory and the Kimberley region in Western Australia.
Helen Thayer is a New Zealand-born explorer who lives in the United States. In 2009, Thayer was named one of the most important explorers of the 20th century by the National Geographic Society.
The geography of South Australia incorporates the south central part of the continent of Australia. It is one of the six states of Australia. South Australia is bordered on the west by Western Australia, to the north by the Northern Territory, Queensland to the northeast, and both New South Wales and Victoria to the east. South Australia's south coast is flanked by the Great Australian Bight and the Southern Ocean.
The 4 Deserts Ultramarathon Series is an annual series of four 250-kilometer (155-mile) races across deserts around the globe. The races were recognized as the world's leading endurance footrace series by TIME magazine in 2009 and 2010, as the "Ultimate test of human endurance". The series was founded by American Mary K Gadams who founded RacingThePlanet in 2002.
A desert is a landscape where little precipitation occurs and, consequently, living conditions create unique biomes and ecosystems. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location.
The deserts of California are the distinct deserts that each have unique ecosystems and habitats. The deserts are home to a sociocultural and historical "Old West" collection of legends, districts, and communities, and they also form a popular tourism region of dramatic natural features and recreational development. Part of this region was even proposed to become a new county due to cultural, economic and geographic differences relative to the rest of the more urban region.
The Gobi Desert is a large, cold desert and grassland region located in northern China and southern Mongolia. It is the sixth largest desert in the world. The name of the desert comes from the Mongolian word gobi, used to refer to all of the waterless regions in the Mongolian Plateau; in Chinese, gobi is used to refer to rocky, semi-deserts such as the Gobi itself rather than sandy deserts.
Oak Creek Pass is a mountain pass through the Tehachapi Mountains, in Kern County, California. The road across it connects the City of Tehachapi with the Mojave Desert.
Sucheta Kadethankar from Pune India, who is currently known to be an accomplished Yoga Teacher is also known for becoming the first Indian to walk across the Gobi Desert, on 15 July 2011. She walked a distance of 1,000 miles (1,600 km) in Mongolia, Asia's largest desert. Kadethankar was part of a 13-member team from nine countries The guided expedition was supported by four-wheel drive truck, local Mongolian guides and 12 Bactrian camels.
European land exploration of Australia deals with the opening up of the interior of Australia to European settlement which occurred gradually throughout the colonial period, 1788–1900. A number of these explorers are very well known, such as Burke and Wills who are well known for their failed attempt to cross the interior of Australia, as well as Hamilton Hume and Charles Sturt.
John Neville Hare was a British explorer, author, and conservationist, known for campaigning for the preservation of the Wild Bactrian camel.
In 1902, while Lesdain was leading an expedition through the Gobi desert, he crossed the path of another explorer. This latter proved to be Miss Mailey who, dressed in men's clothes, commanded her expedition with assurance borne of the safe culmination of many adventures.
