Crowley Lake Stone Columns Created by Volcanic Activity

Crowley Lake is a reservoir on the upper Owens River in southern Mono County, California. Upon completion of the reservoir in 1941, strange columnar formations, some of which reached heights of as much as 20 feet, were spotted along the reservoir’s eastern shore. Some described them as stone cylinders connected by fortified stone arches that had been completely covered and obscured for millions of years but which had been gradually unmasked by the incessant pummeling of the lake’s powerful waves, whose constant pounding had eroded the more malleable rock at the base of the cliffs encasing these pillars.
The pillars were simply regarded as oddities until 2015, when geologists realized that they were the result of frigid water from melting snow seeping down into volcanic ash, creating tiny holes in the hot ash, which then rose up and out of these same holes. Researchers have now counted nearly 5,000 of these pillars, which appear in groups and vary widely in shape, size and color over an area of 4000 acres, with some of the columns standing as erect as towering pylons.

‘Dragon Eye’ lake – Striking natural phenomenon in Japan

The Kagami Numa, the “Dragon Eye lake” in Japan hides a truly mind-blowing phenomenon. Most of the time it’s pretty ordinary looking, but if you go there from late May through early June you might be lucky to witness its transformation into a “dragon eye” shape.
In the late spring, a great amount of snow melts and pours into the pond, and a ring of open water forms around the edge, leaving a white disk in the middle. Next, a pool of water gathers in the center of the white disk, making the pond look rather like a huge eye.

Grüner See – Alpine park that turns into a lake in the summer

Grüner See (Green Lake) is a lake in Styria, Austria, surrounded by the Hochschwab Mountains and forests. The name “Green Lake” originated because of its emerald-green water. During winter, the lake is only 1–2 m (3–7 ft) deep and the surrounding area is used as a county park. However, in spring, when the temperature rises and snow melts, the basin of land below the mountains fills with water. The lake reaches its maximum depth of around 12 m (39 ft). The waters are at their highest in June when it becomes a destination for divers keen to explore the rare phenomenon. A bridge and a bench could also be found underwater, as well as trails and trees.

Nördlinger – The Medieval Town Built of 72,000 Tons of Diamonds

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.

Colorful swirling patterns in Russia’s sylvinite mines

Colorful swirling patterns in Russia’s Uralkali sylvinite mines. Layers of carnallite — a mineral used in fertilizers — band the tunnel walls, producing these vibrant masterpieces. The breathtaking motifs only came to light after photographer Viktor Lyagushkin decided to share his images.
Viktor said: “If you ask me about my strongest impression, my mind was blown with the fact that the miners created this wonderful underground realm and they did not know that.
“Of course, their main task was to win the ore, and it turned out they created the most beautiful place of work and had no idea they did that.”

Penitentes – Spikey Snow Formations in the Andes resembling to praying folk

Penitentes are snow formations found at high altitudes. They take the form of elongated, thin blades of hardened snow or ice, closely spaced and pointing towards the direction of the sun.
The name comes from the resemblance of a field of penitentes to a crowd of kneeling people doing penance. The formation evokes the tall, pointed habits and hoods worn by brothers of religious orders in the Processions of Penance during Spanish Holy Week. In particular the brothers’ hats are tall, narrow, and white, with a pointed top.
These spires of snow and ice grow over all glaciated and snow-covered areas in the Dry Andes above 4,000 metres (13,000 ft) and range in length from a few centimeters to over 5 meters (16 ft).

Punch hole clouds

A fallstreak hole is a large circular gap, that can appear in  clouds. Such  holes are formed when the water temperature in the clouds is below freezing but the water has not frozen yet due to the failure of ice nucleation. When ice crystals do form they will set off a chain reaction causing the water droplets around the ice crystals to evaporate leaving a large usually circular or elliptical hole.
