Wonders of Nature - from all over the world
Moving Stones
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.
Red Tides
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.
Mamatus Clouds
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.
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 at different sizes as shown above.
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.
Blue Holes
Blue holes are giant and sudden drops in underwater elevation that get their name from the dark and foreboding blue tone they exhibit when viewed from above in relationship to surrounding waters. They can be hundreds of feet deep and while divers are able to explore some of them they are largely devoid of oxygen that would support sea life due to poor water circulation - leaving them eerily empty. Some blue holes, however, contain ancient fossil remains that have been discovered, preserved in their depths.
Columnar Basalt
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.

Narooma, NSW South Coast
Fur Seals on Montague Island, off Narooma, NSW south coast
The sea was rough and choppy. The air smelled of the sea; animal, land and sounds are all blended into one. Such is the wonder of nature.
Montague Island has the state of NSW's only known colony of Australian fur seals, Australian native and migratory birds. We were lucky to spot a few hundred seals. At the peak, there could be a thousand of them basking on the rocky shore or swimming and fishing in the ocean.

Native Flora and Fauna of Australia
One of the many species of egg plant, some edible, some toxic. Some may be food for the birds and animals but unsuitable for human consumption. Can you tell? We were told to try testing it on the a skin patch and eat a little at a time. Daren't you?
Animal wildlife
One of the many rare species of reptiles that thrive on the sandy grounds of the vast interior.

Native Plants in Central Australia - Edible and Poisonous
There are hundreds of species of aubergine / eggplant, some of which are edible. It is best to buy processed and packaged products if you are not an expert in native Australian foods.
Many beautiful flowers in the desert produce nectar which could be used to make syrup.
Our guide holding on to a pretty mauve wild flower.
