America's Little-Known Natural Wonders

Thanks to the work of conservationists and the National Parks Service, the dramatic landscapes of all the top wonders have been preserved, along with the lesser-known national treasures, like the remarkable spires of Fisher Towers or the subterranean marvels of the Lost Sea. Whether it’s a top wonder or a hidden gem, it’s worth remembering the words of Teddy Roosevelt, who looked with wonder across the Grand Canyon and remarked, “Keep it for your children, and your children’s children, and all who come after you.”
