when was the great sand dunes national park established

By the end of November 1806, Pike and his men had reached the site of today's Pueblo, Colorado. The mammoths that once roamed the terrain thousands of years ago are now replaced by bountiful herds of elk. When the lakes and wetlands are full, sand is deposited near the edges forming little sandy beaches. Today, visitors can surf an ocean of sandy slopes, observe the glow of planets and hear sand sing. [1][22], The Rio Grande National Forest is located to the north and southeast while the remaining forested slopes directly to the east of the dunes were redesignated the Great Sand Dunes National Preserve. [10], The sabkha is a wetland region where groundwater rises and falls seasonally, leaving white alkali deposits on the surface. [10], While the top few inches of the dune field are often dry, the dunes are moist year-round due to ongoing precipitation. We havent drilled that deep yet. In 2002, geologists discovered lake shoreline deposits on hills in the southern part of the valley, confirming theories of a huge lake that once covered much of the San Luis Valley floor. From the Rio Grande River and its tributaries, soil and sand blow into the valley. When you visit, hike up the dunes and slide down on a sandboard or sand sled. Though they faced prejudice and poor treatment from some, Buffalo Soldiers overall served their country with honor and bravery, and were awarded more Medals of Honor than any other American military unit during that era. The water then drained through the Rio Grande, likely forming the steep Rio Grande Gorge near Taos, New Mexico. [54] Most of the Sangre de Cristo Wilderness is managed by the U.S. Forest Service while the National Park Service manages the area that has since been designated a national preserve. Water that feeds the creek begins as snowfields high in the Sangre de Cristo Mountains, melts into Medano Lake, and cascades through meadows and forests to join the stream. Grassland species such as elk also use these waters for drinking. Other features include snow-fed creeks originating high in the mountains, and several alpine lakes. Active placer mining operations sprang up along Medano Creek, and in 1932 the Volcanic Mining Company established a gold mill designed to recover gold from the sand. Mammoths disappeared and the people that hunted them moved to wetter regions. Blanca Peak, just southeast of the Dunes, is one of the four sacred mountains of the Navajo, "Sisnaajini". 11999 State Highway 150 Located in the town of Fort Garland, Colorado, on US Highway 160. A Living Connection: Contents 1 History of the area 2 Plants and animals 3 Activities 3.1 Landmarks 4 Types of areas 5 Visitor information History of the area [45] The unpaved road crosses Medano Creek nine times and traverses 4mi (6.4km) of deep sand. Members of the Ladies P.E.O. The water then drained through the Rio Grande River, likely forming the steep Rio Grande Gorge near Taos, New Mexico. The massive dunes have been building and drifting for eons, forever changing their shape. Have you ever heard sand sing? Today, we can only imagine the three-way cultural tension in that moment. [21][10], The dunes cover an area of about 30sqmi (78km2) while the surrounding relatively flat sand sheet which feeds the large dunes is actually the largest component of the entire dunes system, containing about 90% of all the sand in the park. Subalpine forest extends from 9,500ft (2,900m) to tree line at 11,700ft (3,600m). The surges occur at an average interval of about 20 seconds. He crossed the Sangre de Cristos into the San Luis Valley in winter, courting disaster but proving that a winter crossing of this range was possible. The San Luis Valley encompasses the area between the two mountain ranges and is roughly the size of the state of Connecticut. Medano Creek is a popular seasonal stream, meaning that the creek has a dynamic flow perfect for rafting in the late spring and early summers, and dries up in the arid winters. Age in years of some of the archeological sites in Great Sand Dunes, some of the oldest in North America. [53] The IUCN has included the same 51 square miles (132km2) of dunes and surrounding sand sheets on their global list of wilderness areas (management category Ib) since 1976. Here majestic scenery also gives intimate glimpses of life's rich complexity. Great Sand Dunes National Park and Preserve never stays the same, providing a distinctly unique experience for each visitor. [20], Great Sand Dunes National Park and Preserve is located in Saguache and Alamosa Counties, Colorado at approximately 37.75 north latitude and 105.5 west longitude. Great Sand Dunes Visitor Center main number, Download the official NPS app before your next visit, Great Sand Dunes Visitor Center main number. We have since learned that the dune sand extends hundreds of feet into the subsurface, so they are older than initially believed. American Indians and early settlers used this route for travel between the San Luis Valley and the Wet Mountain Valley to the east. The dunes cover an area of about 30sqmi (78km2) and are estimated to contain over 1.2 cubic miles (5billion cubic metres) of sand. Hiking the dunes is one of the most popular park activities. The highest diversity of Rocky Mountain species of plants and animals is found in this ecosystem. [52][53] Congress also designated the Sangre de Cristo Wilderness in 1993, which contains a total of 219,900 acres (343.6sqmi; 889.9km2) of mountainous terrain. [35], More than 250 species of birds have been documented in the park and preserve. A trail to Medano Lake and the summit of Mount Herard is located off Medano Pass Road. The modern road, open only to 4WD, high clearance vehicles, follows the old route, skirting the dunefield before rising to Medano Pass and continuing east into the Wet Mountain Valley. The modern unpaved road follows the old route and is open only to four-wheel drive, and high-clearance vehicles as it passes through deep sand, rises to Medano Pass, and continues east into the Wet Mountain Valley. Even with the opposing storm winds, most sand is still blown toward the mountain ranges. NPS. [11], Visitors must walk across the wide and shallow Medano Creek to reach the dunes in spring and summer. Small underwater sand ridges that act like dams form and break down, creating surges of water that resemble waves. Camping is permitted in most places in the national preserve and at designated sites along the Medano Pass Road, as long as minimum impact guidelines are followed. Fossils from the bottom of an ancient sea are now preserved in high layers of rock in the Sangre de Cristos, illustrating the scale of the uplift. Many species nest in the mountains, forests, grasslands, or wetlands during the summer. Some of the ranch lands are located within the current national park boundary in its southwestern corner,[6] and includes a fenced area that contains a bison herd within 44,000 acres (68.8sqmi; 178.1km2)[58]an area that can only be visited on a guided tour. They named this body of water "Lake Alamosa" after the largest town in the valley. Great Sand Dunes National Park and Preserve hosts many different types of terrain within its parameter. The Baca National Wildlife Refuge lies adjacent to the west, and the slopes of the San Juan Mountains begin at the western edge of the valley. CO Smaller lakes still covered the valley floor, including two broad lakes on the northeastern side of the valley. Trails were improved into wagon routes and eventually into rough roads. The park was originally established as Great Sand Dunes National Monument on March 17, 1932 by President Herbert Hoover. For the people from the Tewa/Tiwa-speaking pueblos along the Rio Grande, it is a different spiritual link. These vast stretches of grass and wildflowers surround the dunefield on three sides. Sand grains are a perfect size for the winds to move. The traditional Ute phrase for the Great Sand Dunes is Saa waap maa nache (sand that moves). He was followed in 1853 by Captain John Gunnison of the Corps of Topographical Engineers. In 1776, Juan Bautista de Anza II and a huge entourage of men and livestock probably passed near the dunes as they returned from a punitive raid against a group of Comanches. [29], The four primary components of the Great Sand Dunes system are the mountain watershed, the dune field, the sand sheet, and the sabkha. 81146, 719 378-6395 Lake Alamosa suddenly receded after its extreme water pressure broke through volcanic deposits in the southern end of the valley. The first known writings about Great Sand Dunes appear in Zebulon Pikes journals of 1807. William Henry Jackson - 1873Kris Illenberger - 2011. Spring conditions vary greatly, from mild and sunny to cold and snowy, with occasional high winds in the afternoon. [14], Mosca Pass Trail is a 7mi (11km) roundtrip hike that follows a small creek through aspen and evergreen forests to Mosca Passelevation 9,737ft (2,968m)[6]in the Sangre de Cristo Range. [6] Elevations range from 7,515ft (2,291m) in the valley west of the dunes, to 13,604ft (4,146m) at the summit of Tijeras Peak in the northern part of the preserve. Closed captioning for this video is available on the park's YouTube Channel: While this explanation does answer in the question above, the story of how the Great Sand Dunes were formed is much more complex, and as new research discoveries occur each year, is continually evolving. The collapse begins when the angle of the dune becomes too large to support the weight. The park was originally established as Great Sand Dunes National Monument on March 17, 1932 by President Herbert Hoover. The act directed the Secretary of the Interior to "establish the Great Sand Dunes National Park when sufficient land having sufficient diversity of resources has been acquired to warrant its designation. The tundra begins about 11,700ft (3,600m) and continues upward to the highest peaks in the park. The America the Beautiful - The National Parks and Federal Recreational Lands Pass Series is your ticket to more than 2,000 federal recreation sites across the United States. Geology of Sand Dunes National Park Geology Great Sand Dunes National Park is a complex geologic story going back millions of years. In the rich tapestry of indigenous history, nineteen Native American tribes have maintained active cultural affiliation to the park and surrounding lands. Much of the sediment that had been brought into the valley from the mountains was unsorted, having a mixture of grain sizes and materials, including muds, silts, clays, and most importantly sands. [23][24] The nearest towns are Crestone to the north, Mosca and Hooper to the west, Blanca and Fort Garland to the south, and Gardner to the east. The dunes system is fairly stable as the opposing wind directions balance each other out over time. [39], The park harbors several endemic insects including the Great Sand Dunes tiger beetle, a circus beetle (Eleodes hirtipennis), Werner's (Amblyderus werneri) and Triplehorn's (Amblyderus triplehorni) ant-like flower beetle, as well as undescribed species of clown beetle, noctuid moth, and robber fly. [18] Frank and Virginia Wellington built a cabin and hand-dug the irrigation ditch that parallels Wellington Ditch Trail located south of the park campground. Lean in for a sniff of these majestic pines, and you can smell the enticing scent of vanilla. How Were the Sand Dunes Formed? Today, tribes such as the Jicarilla Apache have an enduring relationship with the Great Sand Dunes National Park and the National Park Service, and regularly hold cultural and ceremonial events in their traditional homeland. Elk and pronghorn are common, while burrowing owls nest in the ground and other raptors float through the skies searching for mice, kangaroo rats, and short-horned lizards. [8] March is the snowiest month, though some days are above 50F (10C). What are sand dunes? Similar support in the late 1990s resulted in the monuments expansion into a national park and preserve in 2004. The creeks then disappear into the sand sheet, and the sand blows back into the dunefield. [32], Mammals includefrom alpine tundra to low elevation grasslandspika, yellow-bellied marmot, bighorn sheep, black bear, snowshoe hare, Abert's squirrel, gray and red foxes, cougar, coyote, mule deer, water shrew, beaver, porcupine, kangaroo rat, badger, pronghorn, and elk. Today, visitors can surf an ocean of sandy slopes, observe the glow of planets and hear sand sing. These smaller bodies of water and seasonal lakes helped sort the sand from the rest of the sediment. The movement is highly variable and can be as little as a few feet per year to tens of feet in a day. Thousands of years ago the desert valley was covered with large lakes and rich plant life-- excellent habitat for a mammoth that needed to eat over 700 pounds (317kg) of vegetation each day. [10], The main dune field measures roughly 4mi (6.4km) east-to-west and 6mi (9.7km) north-to-south, with an adjacent 6sqmi (16km2) area to the northwest called the Star Dune Complex, for a total of about 30sqmi (78km2). [8] The forested and often snowcapped mountains exceeding 13,000ft (4,000m) to the east is the most prominent feature, towering over the high dunes. Many animals visit the dunes from other habitats, including elk, pronghorn, bison, coyotes, bobcats, and raptors. The plan is to complete the park, making it fully accessible to the public, by acquiring the final piece of privately-held land located within the current park boundaries. They call the lake Sip'ophe (Sandy Place Lake), which is thought to be the springs or lakes immediately west of the dune field. When you visit Great Sand Dunes, you also visit the Old Spanish National Historic Trail, a part of the diverse cultural heritage of the San Luis Valley. While the top few inches of sand are blown around during windstorms, the moist sand remains largely in place. Private property abuts most of the southern boundary of the park. Valdez A., Zimbelman J.R. (2020) Great Sand Dunes. [60], The eventual redesignation as Great Sand Dunes National Park and Preserve was authorized on November 22, 2000, when President Bill Clinton signed the Congressionally-approved Great Sand Dunes National Park and Preserve Act. Indiana Dunes National Park is a United States national park located in northwestern Indiana managed by the National Park Service.It was authorized by Congress in 1966 as the Indiana Dunes National Lakeshore and was redesignated as the nation's 61st national park on February 15, 2019. [50], The dunes and surrounding area were designated a national monument in 1932 after a billsponsored by the P.E.O. Visitors can sand board and sand sled with the right gear and conditions. The land includes the area presently occupied by the bison herd, as well as adjacent meadows and wetland areas. Remnants of these lakes still exist in the form of sabkha wetlands. Federal legislation enacted in 2000 created the Great Sand Dunes National Preserve out of 65 square miles (168 square km) of national forestland to the north and east of the monument. The park and preserve together are approximately 15mi (24km) east-to-west at the widest point, and approximately 15mi (24km) north-to-south, also at the widest point.

The Mosca Pass Toll Road was developed in the 1870s, and stages and the mail route used it regularly through about 1911. Occasional fall storms bring icy rain or snow. [12] Hiking is permitted throughout the dunes with the warning that the sand surface temperature may reach 150 F (66 C) in summer. [24] The major roads through the San Luis Valley are U.S. Route 160 on an eastwest alignment passing south of the park, and U.S. Route 285 on a northsouth alignment passing west of the park and generally parallel to Colorado State Highway 17, which is the closer of the two northsouth roadways.[24].

It is also possible that there is more dune sand under the lake deposits. There are other dunes in Colorado, and in most western states in the US, but none as tall (741feet/ 226 meters) and none as dramatic. Over 200 of the parks ponderosa pines are the only grove of trees on the National Register of Historic Places, called Indian Grove. [58] The land is within the MedanoZapata Ranch, located to the west and south. Although many settlers arrived in the San Luis Valley via the trails from Santa Fe or La Veta Pass, several routes over the Sangre de Cristo Mountains into the San Luis Valley were well-known to American Indians and increasingly used by settlers in the late 1800s. more information on current conditions Visit our keyboard shortcuts docs for details, Geologic Map of Great Sand Dunes National Park, https://doi.org/10.1007/978-3-030-40498-7_7, The Geologic Story of Colorado's Sangre de Cristo Range, Quaternary Geology of the San Luis Basin of Colorado and New Mexico, September 79, 2007, Geoindicator: Dune Formation and Reactivation. The presence of larger rocks along Medano Creek at the base of the dunes, elsewhere on the valley floor, and in buried deposits indicates that some of the sediment has been washed down in torrential flash floods. Gold and silver rushes occurred around the Rockies after 1853, bringing miners by the thousands into the state and stimulating mining businesses that operate to this day. As water levels lower, the sand is then exposed to wind, allowing the aeolian processes to take over. [11], The first known writings about Great Sand Dunes appear in Zebulon Pike's journals of 1807. Avalanches occur naturally during storms, but visitors may be able to hear a fragment of the sound by pushing sand down a dune face. Springer, Cham. [11], Gold and silver rushes occurred around the Rockies after 1853, bringing miners by the thousands into the state and stimulating mining businesses that are still in operation. Colorado Springs and Denver are located a few hours away by car to the northeast. The transition zone between the subalpine forest and alpine tundra is an important refuge during storms for some mammals and birds who primarily live in the tundra. [2] Similar support in the late 1990s resulted in the monument's redesignation as Great Sand Dunes National Park and Preserve in 2000. Learn more on the Trujillo Homesteads page.

Low temperatures during winter nights can be extremely cold, with average low temperatures well below 32F (0C) and record low temperatures below 0F (18C) from November through April. [8] Sediments from the surrounding mountains filled the valley over geologic time periods. Widely supported by local people, the bill was signed into law in 1932 by President Herbert Hoover. The park is located in the San Luis Valley in south central Colorado. Sediments from both mountain ranges filled the deep chasm of the valley, along with huge amounts of water from melting glaciers and rain. In this 8-minute video podcast, Park Ranger Ravis Henry sings and tells their story of Sisnaajini - the White Shell Mountain, as well as the importance of Great Sand Dunes to his people. Below is a history of those who have travelled through or lived near this natural landmark. The park encompasses 44,246 acres and the preserve encompasses 41,686 acres. When the water evaporates away in late summer, minerals similar to baking soda cement sand grains together into a hard, white crust. The Milky Way is most visible over moonless nights from mid-summer through early fall evenings. Partially rebuilt at times in the 1930s through the 1950s, the road was repeatedly closed due to flood damage and is now a hiking trail.
