“Iceberg” is located in the Kegen district of the Almaty region between the villages of Kegen and Shyrganak. Thanks to the fine particles of water that are sprayed high into the sky, the “iceberg” looks like a smoking ice volcano. The “volcano” appears every winter with the arrival of cold weather as a result of an underground spring. When temperatures drop below zero, the water freezes in the form of a volcano cone.
Salt domes are located in the Zagros Mountains, in southwestern Iran. Thick layers of minerals such as halite (common table salt) typically accumulate in closed basins during alternating wet and dry climatic conditions. Over geologic time, these layers of salt are buried under younger layers of rock. The pressure from overlying rock layers causes the lower-density salt to flow upwards. Salt rocks with orange, yellow, red and gray lines, which indicates the existence of metal elements, are also called Rainbow Salt.
The Nördlinger Ries is a giant impact crater in Southern Germany. An asteroid hit this region 15 million years ago creating a crater with a diameter of 25km. The town is located in the crater depression. The immense pressure and heat created tons of small diamonds Stone from this area was quarried and used to build the stone buildings. Approximately 72,000 tonnes of diamonds are hidden in Nördlinger’s buddings. They are scientifically valuable but economically not of interest.
Aerial scenes at the end of Willy Wonka & the Chocolate Factory were filmed there.
Desert rose is the colloquial name given to rose-like formations of crystal clusters of gypsum or baryte which include sand grains. The ‘petals’ are crystals fanning open in radiating flattened crystal clusters. The rosette crystal habit tends to occur when the crystals form in arid sandy conditions, such as the evaporation of a shallow salt basin. The crystals form a circular array of flat plates, giving the rock a shape similar to a rose blossom.
Hair ice, also known as ice wool or frost beard, is a type of ice that forms on dead wood and takes the shape of fine, silky hair. It is somewhat uncommon, and has been reported mostly at latitudes between 45–55 °N in broad leaf forests. Hair ice forms on moist, rotting wood from broad leaf trees when temperatures are slightly under 0 °C (32 °F) and the air is humid. Each of the smooth, silky hairs has a diameter of about 0.02 mm (0.0008 in) and a length of up to 20 cm (8 in). The hairs are brittle, but take the shape of curls and waves. They can maintain their shape for hours and sometimes days. A piece of wood that produces hair ice once may continue to produce it over several years.
In the year 2015, German and Swiss scientists identified the fungus Exidiopsis effusa as key to the formation of hair ice. The fungus was found on every hair ice sample examined by the researchers, and disabling the fungus with fungicide or hot water prevented hair ice formation.
Apis dorsata, the giant honey bee, is a honey bee of South and Southeast Asia, found mainly in forested areas. Since their nests are fairly exposed and accessible to predators, built in exposed places far off the ground, these giant honeybees exhibit strong and aggressive defense strategies. A method that Apis dorsata utilizes against wasps is referred to as “shimmering” behavior or defense waving. Bees in the outer layer thrust their abdomens 90° in an upward direction and shake them in a synchronous way. This may be accompanied by stroking of the wings. The signal is transmitted to nearby workers that also adopt the posture, thus creating a visible — and audible — “ripple” effect across the face of the comb, in an almost identical manner to an audience wave at a crowded stadium. These wave-like patterns repel wasps that get too close to the nests of these bees and serve to confuse the wasp. In turn, the wasp cannot fixate on capturing one bee or getting food from the bees’ nest, so the wasp will seek to find easier prey and leave this nest alone.

Incredible examples of art in nature.
Rainforest Expedition’s Troy Alexander spotted the bizarre maypole-in-miniature in the Southern Peruvian Amazon. Alexander posted a photograph of his discovery to /r/whatsthisbug, a subreddit devoted to identifying insects and their handiwork.
Maly Semyachik is a stratovolcano located in the eastern part of Kamchatka Peninsula, Russia. A hot, acidic crater lake fills the historically active Troitsky Crater, which formed during a large explosive eruption about 400 years ago. The water in the lake has an unusual bright turquoise color. It’s because the waters of the lake are poisonous due to the content of several types of acids and other chemical compounds.The water in the lake never freezes, even when everything is covered with a layer of ice and deep snow.

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‘.
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.
