The embroidered fabric patch souvenirs treasured by the U.S. National Parks visitors can be tracked back to Yellowstone in the early 1900s. Created to be sewn onto park rangers outer clothing, they replaced the metal badges in use since 1894. This puzzle features 62 of our nation's national parks in this delightful collection of emblems, taking you from the Atlantic coastline of Acadia to The Arches of Zion. You'll find the smallest national park--91-acre Gateway Arch in St. Louis--and the largest--eight-million-acre Wrangell-St. Elias in Alaska. And you can virtually visit the 14 national parks designated as UNESCO World Heritage Sites and the 21 chosen as UNESCO Biosphere Reserves.
