Founded 100 years ago, the National Park Service protects the country€s most extraordinary wilderness for generations to come, a system comprising 84 million acres representing a diversity of regions and ecosystems. Audubon National Parks Calendar spotlights a distinctive park each month with a large photograph at the top of the page, more full-color images throughout the grid, and engaging text. The cascading waterfalls and wooded trails of Virginia€s Shenandoah National Park. The breathtaking peaks of California€s Pinnacles, the newest national park. The sheer granite cliffs of El Capitan in Yosemite National Park. And a true frontier: Alaska€s Gates of the Arctic, the country€s northernmost national park and, with no roads, accessible only by air or on foot. Each month is an American treasure.
