Luray Caverns, Virginia

In a 400-million-year-old cave system in rural Virginia you’ll find the world’s largest musical instrument. Visitors have been coming to the Luray Caverns to see limestone columns, stalactites, and stalagmites since the site’s discovery in 1878, and while the natural beauty of the underground world is its own draw, the main attraction is the Great Stalacpipe Organ, built in 1954. When the keys of the organ are pressed, a rubber mallet taps the cluster of nearby stalactites, producing varying tones that echo throughout the site’s sprawling network of caves.

World’s Strangest Natural Wonders

Ever played the game of Twister on water? The green, yellow, and brown polka dots that form on British Columbia’s Spotted Lake each summer make it look like you could.

It’s a far cry from the stereotypical landscapes of clear blue lakes, rolling green hills, and white-sand beaches that inspire most travelers—and that’s part of what makes strange natural wonders like Spotted Lake so thrilling. A recently discovered cave that grows crystals the size of four-story buildings, a lake the color of a strawberry milkshake, and a glacier that seems to bleed sound like they’re from another planet, but can be seen right here on earth, and they remind us that there’s plenty of mystery left to explore.

For billions of years, our planet has been a work in progress. Wind, water, pressure, minerals, heat, and lesser-understood forces mold and shape our environment, carving out caves and canyons, flooding and drying lakes, shaping mountains, shifting shorelines, moving the ground beneath our feet, and creating all manner of strange formations.

Long before scientists were able to offer explanations for the world’s more curious natural achievements, locals have been coming up with their own ideas. Māori legend says the enormous boulders found on New Zealand’s Moeraki Beach are the washed-ashore gourds and sweet potatoes from the wreck of a mythological canoe, while Irish folklore attributes the creation of the Giant’s Causeway to a quarrel that spanned across the sea to Scotland.

Such bizarre formations are, in fact, the result of time and pressure working against soil and rock, an often slow and methodical process that yields showstopping results. Others are the result of a sudden dramatic shift in conditions. Together, they caution us, as author Will Durant wrote in the January 1946 edition of Ladies Home Journal, that “civilization exists by geological consent, subject to change without notice.”

Seeing is believing, so take our tour of the strangest natural wonders—and keep an eye out for what the powerful planetary forces may do next.
