New Mexico's Shiprock Named America's Best Geological Formation!

Devils Tower, Bryce Canyon Hoodoos, Antelope Canyon and Halema'uma'u also winners

From sea to shining sea, the United States is covered in spectacular and sometimes strange geological formations – natural wonders that make it easy to see why it's called America the Beautiful. We asked 10Best readers to vote for their favorite iconic American geological formations, and the results are in.

  • Turnip Rock
    Port Austin, Mich.

    Worn away by millennium of wave erosion from the waters of Lake Huron, tree-topped Turnip Rock juts up from the lake waters not far from Port Austin. During the summer, the formation is accessible via kayak, and in winter visitors can trek (carefully) across the frozen surface of the lake.

  • Delicate Arch
    Arches National Park, Utah

    Arches National Park in Utah is brimming with fantastic rock formations, but if we have to narrow it down to just one, that one would be Delicate Arch. Of the park's 2,000 stone arches, this is the most famous. Measuring 64 feet high and 45 feet across, it's the largest free-standing arch in the park and a symbol of the state of Utah.

  • Monument Valley
    Arizona & Utah

    Monument Valley is defined by its large sandstone formations projecting 400 to 1,000 feet skyward. The sight becomes even more stunning as the sun casts shadows across the desert landscape that surrounds these monumental landmarks. Visitors can tour the area by foot, vehicle or horseback, but a Native American guide truly brings the area's history to life.

  • Natural Bridge
    Natural Bridge, Va.

    Natural Bridge, a stone bridge in the southern Shenandoah Valley that formed when a cavern collapsed, is one of America's oldest tourist destinations. According to local legend, a young George Washington visited the site in 1750 and carved his initials into the stone. Plans are in the works to make the natural wonder a state park.

  • The Wave
    Coyote Buttes, Ariz.

    Situated on the slopes of Coyote Buttes within the Paria Canyon-Vermilion Cliffs Wilderness on the border of Arizona and Utah, The Wave formation is famous for its undulating Navajo sandstone layers. So popular is the formation, despite the difficult hike necessary to reach it, that permits are handed out via a lottery system.

  • Halema'uma'u
    Big Island, Hawaii

    To visit Hawaii Volcanoes National Park is to see geology in action, and nowhere is this more true than at Halema‘uma‘u. From a viewing platform outside the Jaggar Museum, visitors stare in awe at the smoking volcanic crater inside the larger Kilauea Caldera. At night, the lava lake roiling within glows.

  • Antelope Canyon
    Page, Ariz.

    A landscape photographer's dream, Antelope Canyon in Arizona's Lake Powell Navajo Tribal Park features 120-foot red sandstone canyon walls rising up from a stream bed where antelope once roamed freely. This preternaturally beautiful slot canyon is open by guided tour only, but is certainly worth the effort.

  • Bryce Canyon Hoodoos
    Garfield County, Utah

    Nowhere in the world are hoodoo rock formations more abundant than in the northern section of Bryce Canyon National Park. These tall, skinny rock spires range in height from 5 feet to the height of a 10-story building. Visitors to Bryce Canyon can see these unusual formations from overlooks above the Bryce Amphitheater or by hiking the Navajo Loop or Queen's Garden trails.

  • Devils Tower
    Devils Tower, Wyo.

    Long before Close Encounters brought this natural monument to the surface of the collective American consciousness, it already ranked as one of the most visited attractions in the nation. President Theodore Roosevelt declared the 1,267-foot-high rock formation the first national monument in 1906. Once a sacred Native American site, it today attracts rock climbers and geology geeks.

  • Shiprock
    Shiprock, N.M.

    Rising up from the landscape of the Four Corners area of New Mexico is Shiprock, a 1700-foot-high volcanic plug that can be seen for miles in any given direction. Known to the Navajo people as "Tsé Bit' A'í," or "Rock with Wings," Shiprock is what remains of a throat of a volcano, exposed after millions of years of erosion. As a formation sacred to the Navajo people, climbing or hiking Shiprock is forbidden.
