The natural world is full of strange and fascinating geological phenomena that seem almost otherworldly. From rocks that move on their own to underwater sinkholes and rainbow-colored mountains, these phenomena challenge our understanding of how the Earth works and offer glimpses into the incredible forces that shape our planet. In this article, we’ll explore 7 of the most strange and surprising geological phenomena from around the world that you won’t believe exist.

Sailing Stones
The phenomenon of the “Sailing Stones” is a mysterious geological occurrence that has puzzled scientists and intrigued visitors for years. Located in the Racetrack Playa of Death Valley National Park in California, these rocks appear to move across the desert floor on their own, leaving behind long tracks that can stretch for hundreds of feet.
Despite years of study, the cause of this movement is still not fully understood. However, it’s believed to be caused by a combination of factors, including strong winds, slick mud, and ice. During cold desert nights, a thin layer of ice can form on the surface of the playa, creating a slick surface that allows the rocks to move when pushed by even the slightest breeze.
While there have been many theories put forth to explain the Sailing Stones, it wasn’t until the advent of time-lapse photography that scientists were finally able to capture the movement of the rocks in action, providing important new clues about the forces at work in this unusual geological phenomenon.
Fairy Circles
Fairy Circles are circular patches of barren earth surrounded by a ring of tall grasses found in the Namib Desert in southern Africa. These circles are typically between 6 and 30 feet in diameter and are evenly spaced, sometimes covering hundreds of acres.
The cause of these circles has long been a mystery, but there are many theories that attempt to explain this strange phenomenon. One popular theory is that the circles are created by termites, which burrow beneath the surface of the desert and create underground tunnels that allow water to spread evenly throughout the area. This creates a pattern of alternating wet and dry areas that promote the growth of grass around the edges of the circles, while leaving the center barren.
Another theory suggests that the circles are caused by competition between the grasses for limited resources, such as water and nutrients. This leads to a self-organizing pattern of vegetation that creates the distinctive circular shape of the fairy circles.
While the exact cause of the fairy circles is still unknown, they remain a fascinating geological phenomenon that has captured the imaginations of scientists and visitors alike.
Blood Falls
Blood Falls is a geological phenomenon located in Antarctica’s Taylor Glacier. It gets its name from the outflow of iron-rich salty water that flows from the glacier, giving it the appearance of blood.
The water that emerges from Blood Falls is highly saline and contains a high concentration of iron. This creates a reaction with the oxygen in the air, causing the water to turn a deep red color, similar to blood. The water flows from an underground reservoir beneath the glacier, which is believed to have been sealed off from the outside world for millions of years.
Scientists believe that the water in the reservoir is kept liquid due to geothermal heating from the Earth’s interior, which allows it to remain liquid even in the extremely cold temperatures of the Antarctic. The high salt and iron content of the water make it inhospitable to most forms of life, but it is home to a unique community of microorganisms that have adapted to survive in this harsh environment.
Blood Falls is a fascinating example of the unique and extreme geological processes that occur in some of the world’s most inhospitable environments.
Blue Holes
Blue Holes are underwater sinkholes that are found in various parts of the world, but are most famous in the Caribbean Sea. These deep, circular sinkholes are characterized by their dark blue color and their seemingly bottomless depths.
The unique blue color of Blue Holes comes from the depth of the sinkhole, which creates a deep blue color due to the absorption of light at different depths. Some Blue Holes are several hundred feet deep, making them some of the deepest underwater caves in the world.
Blue Holes are home to a variety of marine life, including sharks, turtles, and fish. They are also popular destinations for divers and snorkelers due to their unique beauty and the sense of adventure that comes with exploring an underwater cave.
Some Blue Holes are also significant from a geological standpoint, as they offer scientists a glimpse into the history of the Earth’s climate and sea levels. By analyzing sediment and fossils found in Blue Holes, researchers can learn about past climate patterns and sea level changes, and use this information to better understand the future of our planet.
Giant’s Causeway
Giant’s Causeway is a natural geological formation located in Northern Ireland that consists of over 40,000 hexagonal basalt columns that are interlocked like puzzle pieces. The columns are made of cooled and hardened lava that was erupted from a volcanic fissure about 60 million years ago.
The basalt columns vary in height and width, with some reaching as high as 39 feet. The formation is named after a legend that claims it was created by the giant Finn McCool as a path to Scotland, where he planned to fight his Scottish counterpart, Benandonner.
The unique hexagonal shape of the basalt columns is due to the way the lava cooled and solidified as it flowed into the sea. As the lava cooled, it contracted and cracked, forming the distinctive polygonal shapes that make up the columns.
Giant’s Causeway is a popular tourist attraction and is also recognized as a UNESCO World Heritage Site. It has been the subject of scientific study for centuries, with researchers using it as a natural laboratory to better understand the processes that shape our planet.
Rainbow Mountains
The Rainbow Mountains, also known as the Zhangye Danxia Landform Geological Park, are a natural wonder located in Gansu Province, China. They get their name from their colorful appearance, which is caused by the presence of different minerals that have been compressed and eroded over millions of years.
The Rainbow Mountains are made up of a series of sandstone and mineral deposits that were formed over 24 million years ago. The different colors are the result of the oxidization of iron and other minerals, which created unique bands of red, orange, yellow, green, and blue.
The park is home to a number of hiking trails and viewing platforms that allow visitors to get a closer look at the colorful formations. It is also a popular destination for photography enthusiasts who are drawn to the otherworldly landscape and vibrant colors.
The Rainbow Mountains are an excellent example of the stunning natural beauty that can be found throughout the world. They are a testament to the incredible forces of nature that shape our planet, and offer a unique glimpse into the geological history of the region.
Petrified Forests
Petrified forests are ancient forests that have been turned to stone through a process called petrification. This occurs when trees are buried under sediment or volcanic ash, which cuts off their oxygen supply and prevents them from decomposing. Over time, the minerals in the sediment or ash seep into the wood, replacing the organic material and transforming the trees into stone.
Petrified forests can be found all over the world, with some of the most famous examples located in Arizona’s Petrified Forest National Park and in Yellowstone National Park. In these parks, visitors can see thousands of petrified trees that are millions of years old.
Petrified forests offer a unique glimpse into the past, as they provide scientists with valuable information about ancient ecosystems and climate patterns. By studying the types of trees that have been petrified and the sediment layers surrounding them, researchers can learn about the climate and geography of the area at the time the trees were alive.
Petrified forests are also popular tourist attractions, as they offer visitors the chance to see a natural wonder that is both beautiful and awe-inspiring. Whether exploring the trails of a national park or admiring petrified wood in a museum, petrified forests are a fascinating reminder of the incredible forces of nature that have shaped our planet over millions of years.
