Happy birthday to the US of A! As the United States turns 250 years old, it is a fitting time, perhaps, to honour the enduring spirit of American ingenuity.From native crafts to iconic vehicles, the nation’s heritage is deeply etched into its material culture. For tourists looking to experience this living history, these working factories, studios and preservation sites offer an immersion into more than two-and-a-half centuries of craftsmanship.Indigenous Arts and Cultural Demonstration Programme at the Grand Teton National Park, WyomingThe Grand Teton National Park, in Wyoming, hosts demonstrations of indigenous arts and culture. Photo: Instagram/usinteriorLong before the Declaration of Independence was adopted, on July 4, 1776, the indigenous peoples of what would become the United States were living lives rich in culture – and some of that craftsmanship is on display in the Grand Teton National Park every summer, between May and September.Having run since the mid-1970s at the Colter Bay Visitor Centre, the programme honours the deep, generational ties between the Grand Teton landscape and its people. Every artisan producing the beadwork, quillwork and ledger art on display belongs to the Cheyenne, Apache, Arapaho or one of the park’s 21 other associated tribes.Visitors are given an intimate look at the creative process by sitting face-to-face with the artists as they handcraft pieces inside the visitor centre. The experience extends into Saturday evening speaker sessions at the centre’s amphitheatre, where tribal histories, music and storytelling are shared under the stars.Colonial Williamsburg, Virginia
