If your taste runs to the offbeat and quirky, these top 5 weirdest natural formations should be on your list of places to visit.
5) Bryce Canyon National Park, Utah: This park, located in southwest Utah, is famous for its otherworldly geological formations. Rainwater and frost have carved slot canyons, fins and freestanding pinnacles called "hoodoos," out of the limestone rocks. Hoodoos can range from 5 to 150-feet tall. Native Americans believed hoodoos were people who were turned to stone because of bad deeds, so watch your step.
4) Ringing Rocks Park, Bucks County, Pennsylvania: Get your rock on at Ringing Rocks -- a field filled with rocks that, well, ring like bells when you hit them with a hammer. Not all the rocks ring, though; only a third of the rocks in the area are "live." To this day, scientists are stumped as to why these rocks create such bell-like tones. Theories range from strange electromagnetic activity to aliens.
3) Petrified Forest National Park, Arizona: The Petrified Forest is home to plant and animal fossils that date back more than 200 million years. The park covers around 146 square miles and has one of the world's biggest and most colorful concentrations of petrified wood. Dinosaur fossil have been found here as well -- Jurassic Park, anyone?
2) Chimney Rock, Nebraska: This huge rock formation, which is taller than the Statue of Liberty, served as a natural signpost pointing "west" for thousands of settlers. Who needs GPS when you've got the Chimney Rock?
1) Antelope Canyon, near Page, Arizona: Antelope Canyon, known by the Navajo as "The Place Where Water Runs Through Rocks," was carved out by flash floods. The colorful slot canyons can only be visited via a guided tour. The same flash floods that created the canyons can be dangerous during the rainy season.
