Located in Nye Beach, in Newport, Oregon, this large rock formation was once an astounding sight. The formation, called a sea stack (a column of stones stacked on top of each other caused by wave erosion), was a 100-foot-tall stack that dominated the beach. It got its unique name in the 1800s when early settlers realized it was impossible to get around the huge rock without jumping off its steep sides.
Unfortunately, in the 1890s, a gap created between the rock and its surrounding cliffs caused the arch to collapse after a severe storm hit the spot in 1916. Nowadays, there’s almost nothing left of the formation.
Hillary Step on Mount Everest
Sir Edmund Hillary is known around the world as the first person to ever reach the top of Mount Everest in 1953. And so it made sense to name one of the most challenging parts of the mountain the 'Hillary Step'.
The step is basically a huge boulder located some 200ft from the mountain's peak. Apparently, the boulder loosened after the tragic 2015 earthquake in Nepal, and by May 2017, it seems to have disappeared altogether.
Slim River
Canada is known for having some of the most stunning natural landscapes in the world. Especially when it comes to the Yukon territory. Sadly, one of its most beautiful rivers seemed to disappear overnight in the spring of 2017. In what scientists called the first case of "river piracy" in modern times, the reason for the disappearance seems to have been the retreat of the huge Kaskawulsh Glacier, whose meltwater deviated from the Slim River to a different river.
What's even worse, these changes are causing the Kluane, Yukon's largest lake, to shrink. If you happen to be on the Alaska Highway 1, you'll be able to spot the already receding shoreline of the great lake.
Elephant Rock
Elephant Rock was a beautiful, scenic and extremely popular tourist spot for travelers. Located in the Hopewell Rocks Park, in the Canadian Province of New Brunswick, this stunning Flowerpot Formation disappeared in the spring of 2016.
Apparently, around 200 tons of rocks toppled down from the formation and turned the once-jawdropping spot into ruins. Sadly, this was a prime lookout point for travelers to enjoy the broad range of tides of the Bay of Fundy.
Waimangu Geyser
The eruption of Mount Tarawera, which was the end of the Pink and White Terraces, also had a surprisingly positive outcome, it created the Waimangu Geyser. The geyser, which is also considered a wonder of the world, was named for the black sand and minerals it spewed out and is known to this day as the most powerful geyser in history.
The geyser would erupt roughly every 36 hours and would reach massive heights of 450. Tourists soon began flocking to the area to witness the marvel. In 1903, the geyser’s eruptions began to sputter out and it became completely inactive in 1904.
