Jockey's Ridge State Park is a North Carolina state park in Dare County, North Carolina in the United States. Located in Nags Head, North Carolina, it covers 〔 and includes the tallest active sand dune system in the eastern United States. It is the most visited park within the NC park system.〔()〕 The park is a day-use only park and has no campgrounds. Jockey's Ridge contains three unique ecosystems: the Roanoke Sound, the dune system, and the maritime forest. Often when it rains, water collects near the bottom of the dunes creating temporary ponds known as a vernal pools. Few fauna can be seen around the dunes, although some types of flora, such as tall grass, may be seen near the bottom of the dunes. The park is open year round, except Christmas Day, and does not charge an admission, parking, or program fee. The park's entrance is located at Milepost 12 on S. Croatan Highway/US 158. Ranger-led programs are offered throughout the year. Also available are nature trails, a sound access, and picnic areas. Viewing the sunset over the sound, bird watching, and kite-flying are among the favorite activities of visitors. The park also provides outside bathrooms that are typically open from the last frost of the spring to the first frost of the fall. During the summer months, when visitation is highest, visitors are encouraged to bring water with them. There is no fresh water available within the park. The desert-like environment can be quite harsh and temperatures can reach 110 degrees; the sand can be 30 degrees hotter. The park's visitor center features a museum about the cultural and natural history of the park, including sand dunes, plants and wildlife, weather, pirates and local maritime history.〔http://www.ncparks.gov/Visit/parks/jori/activities.php Exhibit Hall〕 A hang gliding school provides concessionaire hang gliding lessons in the park. The ridge area is accessed either from the back deck of the visitor center or the parking lot via a boardwalk. ==History== Scientists believe that the barrier islands of the Outer Banks were remnants of the last Ice Age, which ended approximately 12,000 years ago. They have also concluded that Jockey's Ridge itself came into being about 7,000 years ago. The process of how this came about is unclear; however, scientists believe that minerals such as quartz were washed from the mountains of the state to the ocean, creating sand. This sand was pushed onto the beaches of the area by storms and hurricanes. Through a process known as saltation the sand was eventually blown onto the area now known as Jockey's Ridge where something caused it to begin building the dune system. At one time, the dunes of the Outer Banks extended all the way to the southern end of Virginia. Many mariners used the ridge as a landmark in navigation of the area for coastal exploration in the 16th century.〔Biggs, Jr., W. and Parnell, J. 1989. State Parks of North Carolina. John F. Blair. Winston-Salem, NC 27103〕 By the early 20th century, the Outer Banks had become a popular tourist area for visitors from the mainland.〔 This in turn led to overdevelopment of the land. As development in the area proceeded, many local people desired the protection of the dune area. Action was precipitated in the summer of 1973, when bulldozing was begun on the sound side of Jockey's Ridge.〔 Carolista Baum, a local resident, was made aware of the bulldozing by her children who were playing in the area. She confronted the operator of the machine and successfully demanded that it be shut down. Petitions soon began in an effort to "Save Our Sand Dune," and the organization "People to Preserve Jockey's Ridge" was formed. On July 25, 1974, Jockey's Ridge was approved for designation as a National Natural Landmark〔Mount Olive Tribune 1975. Mount Olive, North Carolina. May 27, 1975.〕 (see Nags Head Woods and Jockey Ridge NNL). With matching funds from the North Carolina General Assembly and the United States Bureau of Outdoor Recreation, approximately were acquired in 1975 to create Jockey's Ridge State Park. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Jockey's Ridge State Park」の詳細全文を読む スポンサード リンク
