The mysterious moving stones of the packed-mud desert of Death Valley have been a center of scientific controversy for decades. Rocks weighing up to hundreds of pounds
have been known to move up to hundreds of yards at a time. Some scientists have proposed that a combination of strong winds and surface ice account for these movements.
However, this theory does not explain evidence of
different rocks starting side by side and moving at different rates and in disparate directions.
Moreover, the physics calculations do not fully support this theory as wind speeds of hundreds of miles per hour would be needed to move some of the stones.
When a thick lava flow cools, it contracts vertically
but cracks perpendicular to its directional flow with remarkable geometric regularity – in most cases forming a regular grid of remarkable hexagonal extrusions
that almost appear to be made by man.
One of the most famous such examples is the Giant’s Causeway on the coast of Ireland (shown above), though the largest and most widely recognized would be Devil’s Tower in Wyoming.
Basalt also forms different but equally fascinating ways when eruptions are exposed to air or water.Red tides are also known as algal blooms – sudden influxes of massive amounts of colored single-cell algae that can convert entire areas of an ocean or beach into a blood red color. While some of these can be relatively harmless, others can be harbingers of deadly toxins that cause the deaths of fish, birds and marine mammals. In some cases, even humans have been harmed by red tides though no human exposure are known to have been fatal. While they can be fatal,the constituent phytoplankton in ride tides are not harmful in small numbers.
While many see these apparently perfect ice circles
as worthy of conspiracy theorizing, scientists generally accept that they are formed by eddies in the water that spin a sizable piece of ice in a circular motion. As a result of this rotation, other pieces of ice and flotsam wear relatively evenly at the edges of the ice until it slowly forms into an essentially ideal circle. Ice circles have been seen with diameters of over 500 feet and can also at times be found in clusters and groups of different sizes as shown above.
True to their ominous appearance, mammatus clouds are often harbingers of a coming storm or other extreme weather system. Typically composed primarily of ice,
they can extend for hundreds of miles in each direction
and individual formations can remain visibly static
for ten to fifteen minutes at a time. While they may appear foreboding they are merely the messengers – appearing around, before or even after severe weather.
A circumhorizontal fire rainbow arc occurs at a rare confluence of right time and right place for the sun and certain clouds. Crystals within the clouds refract light into the various visible waves of the spectrum but only if they are arrayed correctly relative to the ground below.
Due to the rarity with which all of these events happen in conjunction with one another, there are relatively few remarkable photos of this phenomena.
Ever wonder the truth about UFOs?
Avoided by traditional pilots but loved by sailplane aviators, lenticular clouds are masses of cloud with strong internal uplift that can drive a motorless flyer to high elevations. Their shape is quite often mistaken for a mysterious flying object or the artificial cover for one. Generally, lenticular clouds are formed as wind speeds up while moving around a large land object such as a mountain.
Like light pillars, sundogs are the product of light passing through crystals. The particular shape and orientation of the crystals can have a drastic visual impact for the viewer, producing a longer tail and changing the range of colors one sees. The relative height of the sun in the sky
shifts the distance the sundogs appear to be on either side of the sun. Varying climactic conditions on other planets in our solar system produce halos with up to four sundogs from those planets’ perspectives. Sundogs have been speculated about and discussed since ancient times and written records describing the various attributes of our sun date back the Egyptians and Greeks.
This last phenomena is something most people have seen before – beautiful orange moon hanging low in the sky.
But what causes this phenomena – and, for that matter, does the moon have a color at all? When the moon appears lower on the horizon, rays of light bouncing off it
have to pass through a great deal more of our atmosphere which slowly strips away everything but yellows, oranges and reds.The bottommost image above is true to the hues of the moon but has enhanced colors to more clearly show the differences in shade that illustrate the mixed topography and minerology that tell the story of the moon’s surface. Looking at the colors in combination with the craters one can start to trace the history of impacts and consequent material movements across the face of our mysterious Moon.
