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.

In meteorology, a virga is rain falling from a cloud that evaporates before reaching the ground. At high altitudes the precipitation falls mainly as ice crystals before melting and finally evaporating. The phenomenon is very common in deserts, where low humidity and high temperatures can cause rain to evaporate shortly after being released by clouds. You might see virga in the U.S. West and above the Canadian Prairies, in the Middle East, Australia and North Africa.

Batagayka crater in Siberia, known as the “gateway to hell” by locals, is almost 1 kilometer in length and 86 meters in depth. The structure is named after the near-flowing Batagayka, a right tributary of the river Yana. The land began to sink due to the thawing permafrost in the 1960s after the surrounding forest was cleared. Flooding also contributed to the enlargement of the crater. Archeologists have found ice age fossils buried in the mud around the rim of the crater. The rim is extremely unstable as there are regular landslides into the crater and the permafrost is constantly thawing. The Batagayka crater is making noises too as it consumes large chunks of the area. The crater is currently growing in size and it will likely eat through the entire hill slope before it slows down. Frank Günther of the Alfred Wegener Institute in Potsdam, Germany, showed that over the past decade crater grew by an average of 10 meters per year.
