Guest Post: Sue Travers on Desert Springs, Australia

Please join me in welcoming our special guest for today, Sue Travers, who blogs at her new place, jumping aground, and at Traverselife. In her profile she describes herself as, “Playing around with words and photos has been missing from my life for too long. Here, I'm exploring what fun it can be!” She's sharing some amazing info about Australia for us today.  

A cloud of zebra finches rises from their improbable home, flocking to a stunted, spindly bush amongst the dusty shrubs and trickle of water that passes for an oasis in this desolate, unforgiving landscape.

Crystals of salts and minerals encrust the impossibly flat land for acres around, save for the insignificant mound which I earlier referred to as a hill. When you're desperate for geographical features, the rise of a metre or so justifies the term hill, and you can certainly see for a huge distance from the easy stroll to the highest point.

The crisp crunch underfoot, remarkably reminiscent to the sound of snow under snugly warm boots, is a fine layer of dry, bright white minerals, which hides the sinking softness of fine dust.

Our footsteps leave clear tracks across the plane. Other tracks tell stories of rabbits scuttling quickly from bush to scraggly bush ... and well fed dingoes.

This fragile landscape with natural springs, possibly millions of years old, has been securely fenced to protect the precious ecosystem from sheep and cattle which would trample the plants tenaciously clinging to life.

Few others venture here. From a distance, these springs appear lifeless and boring, yet in reality they're breathtaking. There's a stark beauty, solitude, and the sense of time stood still.

A piece of grass pulled from out of the mineral encrustation clearly shows the density and size of the crystal growth, it's surprisingly hard and feels a bit like a seashell.

The Great Artesian Basin is the only reliable source of water throughout enormous areas of inland Australia, bores have been drilled since white settlers occupied the region. It lies under 23% of the continent, (some 1.7 million square kilometres) including large parts of Queensland, New South Wales and the Northern Territory as well as South Australia. The springs enabled Aboriginals to survive throughout the region for around 50,000 years give or take a few thousand years. The water is ancient - between a mere several thousand years up to nearly 2 million years old! Its existence now allows towns to flourish and vast cattle stations to operate.

The naturally occurring mound springs provide the only permanent water source in this arid region of South Australia. They're home to a number of unusual and rare plants, fish and other creatures and provide refuge for a range of animals in times of drought.

Despite their importance for biodiversity and their fragile nature, a massive uranium mine, Olympic Dam, is allowed to remove 42 million litres of water per day for free from the Great Artesian Basin which feeds the natural springs, resulting in a drop of pressure and complete drying up of the springs in some cases. This is in addition to coal mines and coal seam gas (CSG) which also use large volumes of the water. According to government estimates, the CSG industry alone could extract 300 billion litres over the next 25 years.

Australia, the driest habitable continent on earth, regularly experiences extreme, devastating droughts, encourages mining operations which extract more water than can be replenished. Coal seam gas, fracking, open cut coal mines and uranium mines are dotted above the Great Artesian Basin, all using the water, and disposing of waste - not always in the most desirable ways.

To read that companies "will be held accountable" and that they must specify how they'll respond  to, and repair, a leak or spill doesn't inspire confidence.

As Murphy's Law says "anything that can possibly go wrong, does" except perhaps in the minds of politicians or the mining industry.

Is it worth the risk?

Alphabet Soup - Watching Westerns

This word puzzle is brought to you by Nicole at The Madlab Post...

Although Westerns are not exactly my all-time favorite genre of movies to watch, they still make for some good ol’ Friday word-scrambling fun! Today’s Alphabet Soup game comes with a twist -- many of the following movie titles do not include words that start with the letter W. It’s all about genre this week.

Unscramble the following four movie titles for films that are categorized as Western. The first commenter who is able to correctly unscramble all or most of these screen credits at best wins this weeks’ Alphabet Soup game. Answers to the game and the name of the winner will be posted here at the A to Z blog during the next Friday Fun Time - Alphabet Remix.

The Gap Theory

Okay, let’s take a bit of a breather and think outside the box. The Gap Theory tries to bridge the gap between two camps: some Creationists who believe the universe is 6,000 years old (counting back in time to the Garden of Eden and Adam and Eve) and science which claims the universe is around 14 billion years old.

Basically, the theory states there is an undetermined amount of time between Genesis 1:1 and Genesis 1:2. “In the beginning God created the heavens and the earth (insert Gap Theory). And the earth was without form, and empty; and the darkness was upon the face of the deep. And the Spirit of God moved on the face of the waters.
God created everything in Genesis 1:1. Following verse two, He simply spoke the world as we know it today into being since all the elements and forces had already been created in verse one. “And God said let there be …..”

This Gap Theory would allow for dinosaurs, cavemen, and the universe being 14 billion years old according to science. People in both camps make valid arguments for and against the Gap Theory and can be very passionate in their beliefs. Even hostile.

Me personally, I lean in the direction of the Gap Theory. I’ve heard both arguments in great detail and do not see a problem.

Question: What do you think of the Gap Theory?
