America’s Top Natural Wonders - Yosemite, Yellowstone Outdoors
America' s Top 10 Natural Wonders
Yellowstone Caldera Wyoming and Montana
The Yellowstone Caldera is the beating heart of a supervolcano. It's also the hot spot that fuels all of the amazing thermal features in Yellowstone National Park, including geysers, such as Old Faithful, and the numerous hot springs, gurgling mud pots and steaming fumaroles. Yosemite Valley California
This is one of the most beautiful places on earth. The panorama includes El Capitan, the world's largest monolith of exposed granite; the distinctive Half Dome granite formation; and Yosemite Falls, the tallest waterfall in North America, measuring 2,425 feet from top to bottom. Bryce Canyon Utah
Of all the stunning geology in the southern reaches of Utah, Bryce Canyon stands out. The distinctive and otherworldly sandstone formations known as hoodoos that populate the valley floor were once rocks that slowly lost portions to the erosive forces of water and air. The Everglades Florida
In wet season, Florida's southern tip essentially becomes a massive, slow-moving river that's roughly 60 miles wide and 100 miles long. The wildlife that call this swamp home include alligators, panthers, armadillos and manatees. AARP Offer Explore Your World

The tallest mountain in North America, Denali looms above 6 million acres of national park and preserve. Grizzly bears and other wildlife are rife on both the low-elevation taiga and the alpine tundra. Death Valley California
The lowest, hottest place in North America, Death Valley bottoms out at Badwater Basin (282 feet below sea level) and has topped out at 134 degrees Fahrenheit. But it's not all scorching desert: Telescope Peak (11,043 feet) towers over the valley. Great Sand Dunes Colorado
Rising from the sage-studded floor of the San Luis Valley in southern Colorado are the tallest sand dunes in North America. The aptly named 650-foot High Dune offers persevering hikers an amazing view into the heart of the dune field, an amazing byproduct of water, wind and time. Mammoth Cave Kentucky
The only subterranean spot on our list of top 10 natural wonders, Mammoth Cave is the largest known cave system on the planet. The natural labyrinth consists of nearly 367 explored miles of serpentine tunnels and is 400 feet underground. Teton Range Wyoming
The most iconic mountains in the West rise higher than 10,000 feet above the floor of Jackson Hole, home to the meandering Snake River and unforgettable vistas around every bend. South of Grand Teton National Park is the world-class skiing mecca Jackson Hole Mountain Resort. Redwood Coast California
This rugged, wild coastline is home to the world's tallest trees: the coast redwoods, which can top out at 350 feet or more. The location of the tallest one, the 379-foot Hyperion, is a closely guarded secret to keep crowds away. Also of Interest
