Mono Lake Tufa State Natural Reserve is located near Yosemite National Park within Mono County, in eastern California. The lack of an outlet to the ocean causes high levels of salts to accumulate in the lake. Many columns of limestone rise above the surface of Mono Lake. These limestone towers consist primarily of calcium carbonate minerals. This type of limestone rock is referred to as tufa, which is a term used for limestone that forms in low to moderate temperatures. The tufa originally formed at the bottom of the lake. It took many decades or even centuries to form the well-recognized tufa towers. When lake levels fell, the tufa towers came to rise above the water surface and stand as the majestic pillars seen today.

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.

Thermogenic plants have the ability to raise their temperature above that of the surrounding air. They can generate their own heat and flower earlier in the season than almost any other plant. Botanists are not completely sure why thermogenic plants generate large amounts of excess heat, but most suspect the flowers may be doing this to attract coldblooded insect pollinators. Thermogenic plants are found in a variety of families, but Araceae in particular contains many such species. Here’s some examples.
Symplocarpus foetidus, commonly known as skunk cabbage, is a low growing plant that grows in wetlands and moist hill slopes of eastern North America. Bruised leaves present a fragrance reminiscent of skunk.

YND 223-14 Cafe in western Seoul looks like an optical illusion in which the tables, chairs, decorations and floor have lost all depth. Even the drinks are served in cups designed to look like they are part of a drawing. The design concept was inspired by a TV show in which the characters are caught partway between the real world and a cartoon existence. A black and white wonder where you can drink coffee and eat fancy treats.
