The world is filled with stunning landscapes and breath-taking terrains that are the result of hundreds and even thousands of years of changes on our ever-evolving planet. The Earth’s surface is constantly being shaped and reshaped by tectonic activity, water erosion, air currents and even heat. Because of this, in the past 100 years, many of our natural wonders have become a thing of the past, lost to history. Here are five natural wonders that are no longer with us.

1. Azure Window, Malta

Malta’s Azure Window is an arch that was carved into Gozo’s Island’s limestone cliffs over the span of hundreds of years. For a long time, it withstood thousands of storms; all but one on March 8, 2017, when it collapsed into the sea. All hope is not lost though, because renowned architect Svetozar Andreev, and designer Elena Britanishkaya have collaborated to restore the historical landmark in the form of a massive piece of art. The amazing project has already been dubbed by the excited locals as “The Heart of Malta.”

2. Valley of Geysers, Russia

Kamchatka Peninsula, Russia was home to the 3.7-mile-long Valley of Geysers, which was previously home to a large number of geysers, thermal fields, boiling springs and waters. Sadly, most of the geysers are gone due to a massive landslide in 2007 which came with snow, stones and water that engulfed everything in its path. The nearby river flooded and created a dam which consumed most of the valley’s spectacular features. The water receded over the following few months, but it’s clear that the valley’s beauty has been changed forever.

3. Old Man of the Mountain, New Hampshire

The Old Man of the Mountain was an iconic granite rock face in New Hampshire that eerily resembled a face carved into the mountainside. The angular rocky outcrop stood nearly 45 feet tall and 30 feet wide in an area that was prone to freeze-thaw corrosion. It was already predicted by geologists that the rock formation would collapse; the dreaded day was May 3, 2003. Despite geologists’ earlier predictions, many were still stunned at the news of the Old Man’s demise, which included local residents who mourned the loss of their beloved monument. 

4. Sequoia Tunnel Tree, California

The Calaveras Big Trees State Park, California, is home to several giant sequoia trees. These trees are so valuable that a few of them were carved through to create a road instead of chopping them down. The most famous of them all was the Yosemite’s Wawona Tree, which was estimated to be around 2,100 years old when a storm sent it crashing down in 1969. 

5. God’s Finger, Spain

Here’s another famous rocky landmark – El Dedo de Dios or “God’s Finger,” a symbol of Gran Canaria in the Canary Islands. The rock’s unique shape has served as inspiration for numerous artists throughout the years. Sometime in November 2004, tropical storm Delta sent massive waves across the island’s coastline, toppling off a good chunk of the 300,000-year-old landmark. “God’s Finger” was badly damaged and although a team of experts considered rebuilding it, many other people advised against it and instead planned to preserve what was left of it.
