>Nothing compares with the giants found in Cueva de los Cristales, or Cave of Crystals. The limestone cavern and its glittering beams were discovered in 2000 by a pair of brothers drilling nearly a thousand feet below ground in the Naica mine, one of Mexico's most productive, yielding tons of lead and silver each year. The brothers were astonished by their find, but it was not without precedent. The geologic processes that create lead and silver also provide raw materials for crystals, and at Naica, miners had hammered into chambers of impressive, though much smaller, crystals before

Pic is Alexandrite
The alexandrite variety displays a color change (alexandrite effect) dependent upon the nature of ambient lighting. Alexandrite effect is the phenomenon of an observed color change from greenish to reddish with a change in source illumination.[8] Alexandrite results from small scale replacement of aluminium by chromium ions in the crystal structure, which causes intense absorption of light over a narrow range of wavelengths in the yellow region (580 nm) of the visible light spectrum.[8] Because human vision is most sensitive to green light and least sensitive to red light, alexandrite appears greenish in daylight where the full spectrum of visible light is present, and reddish in incandescent light which emits less green and blue spectrum.[8] This color change is independent of any change of hue with viewing direction through the crystal that would arise from pleochroism.[8]

https://en.wikipedia.org/wiki/Tsunami_bomb
>The tsunami bomb was an attempt during World War II to develop a tectonic weapon that could create destructive tsunamis. The project commenced after US Navy officer E.A. Gibson noticed small waves generated by explosions used to clear coral reefs. The idea was developed by the United States and New Zealand military in a programme code named Project Seal.[1] The weapons concept was deemed feasible, but the weapons themselves were never fully developed or used. A related concept, the bouncing bomb was developed and used in World War II, to be dropped into water as a means to destroy German dams and cause loss of industrial capacity and widespread flooding.
That was attempted during WW2. I wonder what could be done with modern technology.

If you examine this material closely, you will find that it is a sandstone in which the sand grains are bound together by a cement of clear precious opal.

A star sapphire is a type of sapphire that exhibits a star-like phenomenon known as asterism; red stones are known as "star rubies". Star sapphires contain intersecting needle-like inclusions following the underlying crystal structure that causes the appearance of a six-rayed "star"-shaped pattern when viewed with a single overhead light source. The inclusion is often the mineral rutile, a mineral composed primarily of titanium dioxide.

The third highest mountain in north america is only 17 miles away from sea level, in the Tann Fiord near Icy Bay Alaska.
In October 2015, there was a landslide on the mountain that generated a tsunami wave over 500 ft high that swept over Icy Bay.
>The wave that followed ripped spruce from 1,700 feet up a mountain slope and left trimlines in the bay that are visible today.
>Last October, seismologists at Columbia University in New York detected the Icy Bay landslide on their instruments. Göran Ekström and Colin Stark specialize in picking up landslide signals. They figured the slide spilled 200 million tons of rock in 60 seconds.
>Scientists estimate the Icy Bay slide might be the biggest non-volcanic landslide, by volume, in North America’s written history.

The landscape is presented in multi-colors, such as red, yellow, orange, blue, white and grey. Some mountains look like a watercolor painting while others like a Chinese brush drawing. Being in such a wonderland, you will feel like you were in a fairy tale.
Danxia landform is created by red-colored sandstones and mud stones. It was listed as one of the 10 most amazing geographic wonders of the world by the National Geographic magazine in 2011.

A fossil natural nuclear fission reactor is a uranium deposit where self-sustaining nuclear chain reactions have occurred. This can be examined by analysis of isotope ratios. The conditions under which a natural nuclear reactor could exist had been predicted in 1956 by Paul Kazuo Kuroda. The phenomenon was discovered in 1972 in Oklo, Gabon by French physicist Francis Perrin under conditions very similar to what was predicted.
Oklo is the only known location for this in the world and consists of 16 sites at which self-sustaining nuclear fission reactions are thought to have taken place approximately 1.7 billion years ago, and ran for a few hundred thousand years, averaging probably less than 100 kW of thermal power during that time.
