The Great Smoky Mountains National Park was celebrating its 75th anniversary in 2009. The park is located in areas of two southeastern states, Tennessee and North Carolina. The Great Smoky Mountains National Park is America’s most visited national park. More than nine million people went there last year. The park has more than 1 000 kilometres of trails. Visitors can camp, fish, ride bicycles or drive through the park. There are more than 1 600 kinds of flowering plants. The Park Service says the park has more kinds of flowering plants than any other national park in North America. It also has animals including deer, elk (麋) and more than 1 500 bears. (30) The Great Smoky Mountains National Park was created by local citizens who wanted to protect the area. But they needed money to buy the land from farmers and other owners. The money came from the legislatures of Tennessee and North Carolina. It also came from individuals and groups including the Laura Spellman Rockefeller Foundation. The official dedication did not take place until 1940, when President Franklin Roosevelt spoke at a ceremony in the park. The ceremony took place at the Rockefeller Monument, on the borderline between the two states that provided the land. Earlier this month, officials rededicated the park at a ceremony held on that same spot. One of the guests was Dolly Parton. The country singer grew up in the Great Smoky Mountains, and wrote a fund-raising CD for the 75th anniversary. (31)We leave you with Dolly Parton and a song called My Mountains, My Home.
