Tufa towers rise up from the water at Mono Lake, California, shortly after sunrise
-
Mono Lake, California is a place of special beauty. Tufas are limstone formation that only built up under water; because water level has been drained to provide drinking water to Southern California Tufas are now visible outside of water. Mono Lake lies in the High Sierras just outside the eastern entrance of Yosemite National Park.

The iconic South Tufa at Mono Lake, CA. On a five-day road-trip around California I made sure to swing past, as this was a spot I had wanted to shoot at for a while. I really couldn’t have asked for better lighting. The layered clouds made for a spectacular backdrop against the sky, and the shifting light meant that the view changed every few moments- you can see in this shot that the tufa in the centre of the shot are in light while off of to the right, the water and formations are in shadow. With a polarizer filter, the contrast in the sky and with the calcified features was so striking. While I can’t wait to go back someday for a shoot with my whole kit, I have to say I thoroughly enjoyed myself that afternoon. May 2007.

the colour of the water in this stream has to be seen in person – it really is that colour! the water running over calcified rocks helps to create this beautiful wonder of nature…image taken near cardwell in north queensland… / see more of my work from australia… australia

Tufa is a build up of calcium that forms around underwater springs over long periods of time. They are now exposed because the water level at Mono Lake is low. What you are seeing is actually exposed lakebed that was underwater 100 years ago. How did it get so low? Because Los Angeles pumps its water from the streams that feed this lake. Then they send the water through an aquaduct for hundreds of miles until it gets to LA. They can steal all of this water because long ago they bought all the land from under the ranchers here for its water rights. Seems wrong to me that a city can buy up all this land so far away from its city boundaries and that they can essentially put the area into a never-ending drought. This is an HDR composed of 5 exposures taken 1 stop apart.

Blossom’s_Photo_Gallery Marakoopa Cave is a limestone cave in Mole Creek Karst National Park, north-west Tasmania. Mole Creek Karst National Park is a 40 minute drive west of Deloraine. The Mole Creek Karst National Park includes some of Tasmania’s most visited cave systems, including Marakoopa and King Solomons Cave, two of over 300 known caves and sinkholes in the area. A stalactite is a deposit of calcium carbonate which hangs from the ceiling or wall of a limestone cave and is formed by the dripping of mineralized solutions. The term “stalactite” is derived from the Greek meaning to fall in drops. Marakoopa Caves, Mole Creek Karst National Park, north-west Tasmania, Australia.

Jenolan Caves are Australia’s most impressive limestone caves. The caves were discovered in 1838 by a convict bushranger. There are nine show caves open to the public with spectacular lighting, underground rivers and cave formations.

Hot calcium-laden waters spring from the earth and cascade over a cliff. As they cool they form dramatic travertines of hard, brilliantly white calcium that form pools. Pamukkale, Turkey.

This is the last batch of my The Hidden Land collection from the Australian Museum. As before, the handicaps and limitations of the shots are the same – behind glass cases and limited lighting. This collection features rocks and minerals highlighting their unique properties and formations. I always try to take as macro a shot as I can without loosing too much information about my subjects. Some post work was needed to bring out the textures and balance the lighting – Tone Curve, Saturation and Gamma.

It is a common substance found in rock in all parts of the world, and is the main component of shells of marine organisms, snails, pearls, and eggshells. Calcium carbonate is the active ingredient in agricultural lime, and is usually the principal cause of hard water. It is commonly used medicinally as a calcium supplement or as an antacid, but excessive consumption can be hazardous.The vast majority of calcium carbonate used in industry is extracted by mining or quarrying. Pure calcium carbonate (e.g. for food or pharmaceutical use), can be produced from a pure quarried source (usually marble). / The trigonal crystal structure of calcite is most common. To test whether a mineral or rock contains carbonate, strong acids such as hydrochloric acid or sulfuric acid can be added to it; if the sample does contain carbonate, it will fizz and produce carbon dioxide and water. (Although sulfuric acid reacts, the reaction soon ceases because the calcium sulfate produced is rather insoluble in water and limits the reaction.) Weak acids such as acetic acid will react, albeit less vigorously. All of the rocks and minerals mentioned above will react with acid. / To test for calcium, prepare a platinum or nichrome wire and dip it into some hydrochloric acid. Then dip the wire into some crushed sample to be tested. Place the wire in a bunsen burner flame; if calcium is presented in the sample a brick-red flame will be produced. / If a sample gives positive results for both of the two tests above, the presence of calcium carbonate is indicated. / Carbonate is found frequently in geologic settings. It is found as a polymorph. A polymorph is a mineral with the same chemical formula but different chemical structure. Aragonite, limestone, chalk, marble, and others all have CaCO3 as their formula but each has a slightly different chemical structure. Calcite, as calcium carbonate is commonly referred to in geology is commonly talked about in marine settings. Calcite is typically found around the warm tropic environments. This is due to its chemistry and properties. Calcite is able to precipitate in warmer shallow environments than it does under colder environments. This is analogous to CO2 being dissolved in soda. When you take the cap off of a soda bottle, the CO2 rushes out. As the soda warms up, carbon dioxide is released. This same principle can be applied to calcite in the ocean. / In tropic settings, the waters are warm. Consequently, you will see many more coral in this environment than you would towards the poles where the waters are cold. Also, since carbonate precipitation does not favor pressure, corals and such are typically only found in shallow environments from: Wikipedia
