Kelvin-Helmholtz clouds, also known as ‘billow clouds’, look like rolling ocean waves in the sky. The clouds often form on windy days, when two air currents of varying speeds meet in the atmosphere. It’s believed that this kind of clouds inspired the swirls in van Gogh’s ‘Starry Night‘.
Fjaðrárgljúfur is a canyon in south east Iceland. The Fjaðrá river flows through it. The canyon has steep walls and winding water. It is up to 100 m deep and about 2 kilometers long. Its origins date back to the cold periods of the Ice Age, about two million years ago. The canyon was created by progressive erosion by flowing water from glaciers through the rocks and palagonite over millennia. A waterfall flows down the western side of the canyon, visible from an observation platform at the end of a one-mile hike up the eastern edge.
In May 2019, authorities closed the canyon to visitors after it appeared in a music video by Justin Bieber. The resulting stream of visitors threatened to damage the canyon’s environment.
Hashima Island , commonly called Gunkanjima (meaning Battleship Island), is an abandoned island lying about 15 kilometers (9 miles) from the city of Nagasaki, in southern Japan. The island’s most notable features are its abandoned concrete buildings, undisturbed except by nature, and the surrounding sea wall. The island established in 1887 during the industrialization of Japan and was known for its undersea coal mines. In 1974, with the coal reserves nearing depletion, the mine was closed and all of the residents departed soon after, Interest in the island re-emerged in the 2000s on account of its undisturbed historic ruins, and it gradually became a tourist attraction. Certain collapsed exterior walls have since been restored, and travel to Hashima was re-opened to tourists in 2009. While the island is a symbol of the rapid industrialization of Japan, it is also a reminder of its history as a site of forced labor prior to and during the Second World War.

Torres del Paine National Park encompasses mountains, glaciers, lakes, and rivers in southern Chilean Patagonia. The Torres del Paine are the distinctive three granite peaks of the Paine mountain range. The landscape of the park is dominated by the Paine massif, which is an eastern spur of the Andes located on the east side of the Grey Glacier, rising dramatically above the Patagonian steppe. Small valleys separate the spectacular granite spires and mountains of the massif.

Meoto Iwa , or the Married Couple Rocks, are two rocky stacks in the sea off Futami, Japan. They are joined by a shimenawa (a heavy rope of rice straw) and are considered sacred by worshippers at the neighboring Futami Okitama Shrine. According to Shinto, the rocks represent the union of the creator of kami, Izanagi and Izanami. The rope, which weighs over a ton, must be replaced several times a year in a special ceremony.
At dawn during the summer, the sun appears to rise between the two rocks. Mount Fuji is visible in the distance. At low tide, the rocks are not separated by water. Numerous frog sculptures can be seen in the vicinity of the Futami Okitama Shrine as they are believed to be a type of charm for bringing people or things back.
