“We have calcium in our bones, iron in our veins, carbon in our souls, and nitrogen in our brains. 93 percent stardust, with souls made of flames, we are all just stars that have people names.”
Spotted Lake is a small lake rich in a variety of minerals, including calcium, sodium sulphates and magnesium sulphate. During the hot summer months, much of the water in the lake evaporates, leaving concentrations of these minerals that form the spots visible in the lake. Throughout the summer, the spots shift in size and colour as the minerals within each change with further evaporation. Colours ranging from blue to green to yellow appear, depending on the mineral makeup of each individual spot.
Spotted Lake is known to the First Nations People of the Osoyoos area as kłlilx’w, and it is a sacred site that has been considered a revered place of healing for centuries. The belief is that each of the different circles holds its own unique medicinal and healing properties. The land surrounding the lake was privately owned for 40 years, but in 2001 the federal government acquired it for the benefit and uses of the Okanagan Nation. This ensures that this historically important land can be protected from development, so that future generations of the Okanagan Nation will continue to benefit, as did their ancestors.

Mooney Falls is the fourth main waterfall in the Havasu Canyon.
The falls are about 210 feet (64 m) tall and fall into a rocky pool.
The Havasu Creek is well known for its blue-green color and distinctive travertine formations. This is due to large amounts of calcium carbonate in the water that formed the limestone that lines the creek and reflects its color so strongly (source: Wikipedia).

Not a good place for a tree seed to drop.
Several thousand pounds of calcium carbonate, carried in solution from the hot springs that bubble up through thick limestone, are deposited onto the enormous terraces each day. As the terrace complex spreads and grows, surrounding vegetation is overtaken. In this photo several dead trees are seen embedded in calcium carbonate, with steaming water flowing around them.
"Terrace Mountain at Mammoth Hot Springs is the largest known carbonate-depositing spring in the world. It was created over thousands of years as hot water from the spring cooled and deposited calcium carbonate (over two tons flow into Mammoth each day in a solution). Because of the huge amount of geothermal vents, travertine flourishes.
The hot water that feeds Mammoth comes from Norris Geyser Basin after traveling underground via a fault line that runs through limestone and roughly parallel to the Norris-to-Mammoth road." Wikipedia

SIENA E DINTORNI (CRETE SENESI-VAL D'ORCIA)
Camellia is a genus of flowering plants in the family Theaceae. Camellias are evergreen shrubs or small trees up to 20 m tall. They are found in eastern and southern Asia, from the Himalayas east to Japan and Indonesia. There are about 300 species and around 3,000 hybrids. Their flowers are usually large and conspicuous, one to 12 cm in diameter, with five to nine petals in naturally occurring species of camellias. The colors of the flowers vary from white through pink colors to red. Of economic importance in East Asia, Southeast Asia, and the Indian subcontinent, leaves of C. sinensis are processed to create the popular beverage tea. The ornamental C. japonica, C. sasanqua and their hybrids are the source of hundreds of garden cultivars. C. oleifera produces tea seed oil, used in cooking and cosmetics. The various species of camellia plants are generally well-adapted to acid soils rich in humus, and most species do not grow well on chalky soil or other calcium-rich soils. Most species of camellias also require a large amount of water, either from natural rainfall or from irrigation, and the plants will not tolerate droughts. However, some of the more unusual camellias – typically species from karst soils in Vietnam – can grow without too much water. 3027

Pamukkale
Pamukkale was formed when a spring with a high content of dissolved calcium bicarbonate cascaded over the edge of the cliff, which cooled and hardened leaving calcium deposits. This formed into natural pools, shelves and ridges, which tourists could plunge and splash in the warm water.

Standing on the bridge gives the most amazing view of Bruarfoss. I know what everyone is thinking and Yes! The water IS really that blue. The black volcanic stone and the bright calcium water provide a stunning contrast.
The female whitetails (does) enter estrus in late October and November so starting in early October the males (stags / bucks) start seeking out the locations of the does prior to the breeding season starting.
Every year the bucks shed their antlers and grow a new set in preparation for battle and hopefully attain dominance in his area. The length and branching of the antlers is determined by nutrition, age and genetics. Protein and calcium intake plus good genetics produces some admirable sets of antlers.
This young buck that I caught trying to sneak around behind me is not in his prime yet but does have a nice evenly matched 8 point set of antlers.
Mammoth Hot Springs is a large complex of hot springs on a hill of travertine in Yellowstone National Park adjacent to Fort Yellowstone and the Mammoth Hot Springs Historic District. It was created over thousands of years as hot water from the spring cooled and deposited calcium carbonate. Because of the huge amount of geothermal vents, travertine flourishes.
Palette Spring is a natural hot spring located in the Mammoth region of Wyoming. This attraction offers visitors an opportunity to witness the mesmerizing interplay of colors created by the minerals in the spring’s water, which are a direct result of the geothermal activity in the area. The vibrant hues, ranging from deep blues to rich oranges, create a picturesque scene.

The Cathedral Cliffs reflect in part of the Swamp Lake Fen near Crandall, Wyoming. This pond at the base of the Catherdral cliffs in the Shoshone National Forest is an unique wetland designated as a Special Botanical Area. The majority of the wetlands are in the Swamp Lake Fen which is a combination of marsh, forest and open water. Fens are peat-forming wetlands that rely on groundwater input. They require thousands of years to develop and cannot easily be restored once destroyed. Swamp Lake Fen is fed by ground water from the limestone Cathedral Cliffs which bound it on the south as shown in the photo. The resulting ground water is enriched with calcium carbonate and is alkaline (pH near or above 8). According to the US Forest Service, alkaline fens are rare and 19 Wyoming Species of Concern are listed at Swamp Lake. (See reference).

The court-confirmed minimum level of Mono Lake is several feet higher than the lake ahs been in recent years. It's hard to say when the lake might regain that depth, but when it does many of the calcium carbonate tufa rock formations that we see today will be at least partially submerged.
Captured while leading a seminar for the Mono Lake Committee in November 2019. Lori Hibbett and I will be leading another Mono Lake Moon Rise and Winter Light workshop at Mono Lake December 17-19, 2022.
The upper terraces at Canary Springs which is part of Mammoth Hot Springs are composed of calcium carbonate. The terraces are colored by orange, yellows and cream colored thermophilic organisms. The water for the hot springs comes from precipitation in the surrounding mountains that runs down into the subsurface. The water is heated at depth. As the water rises it dissolves limestone in the subsurface beneath Mammoth and the surrounding mountains. The hot carbonate rich water comes to the surface and forms the travertine terraces. Geologists estimate that at any given time about 10% of the water in Mammoth Hot Springs is on the surface. The other 90% remains underground.
All tufa at Mono Lake forms underwater. Beneath Mono Lake, calcium-rich freshwater springs seep up from the lake bottom and mix with lake water rich in carbonates. As the calcium comes in contact with the carbonates in the lake, a chemical reaction occurs, resulting in calcium carbonate, or limestone. The calcium carbonate settles out of solution as a solid around the spring, and over the course of time, a tufa tower grows. Tufa towers can grow to heights of more than 30 feet underwater. If the water level falls and the tufa is exposed to air, it can no longer grow and the towers are susceptible to erosion.
When you consider how tall the tufa tower is in this photo (15-20 feet) you get a good sense of how much water has evaporated since water that used to feed Mono Lake was diverted to southern California in 1941.
Mono Lake has actually risen since 1994 when state officials limited the diversions. They ordered the level must eventually rise to reach 6,392 feet above sea level. In 2025, the water level is about 9 feet below its legal limit.

The upper terraces at Canary Springs which are part of Mammoth Hot Springs are composed of calcium carbonate. The chalky white and gray colors show where there is no current hot springs flow or terrace building. Active terraces are colored by orange, yellows and cream colors caused by thermophilic organisms. The water for the hot springs comes from precipitation in the surrounding mountains that runs down into the subsurface. The water is heated at depth. As the water rises it dissolves limestone in the subsurface beneath Mammoth and the surrounding mountains. The hot carbonate rich water comes to the surface and forms the travertine terraces. Geologists estimate that at any given time about 10% of the water in Mammoth Hot Springs is on the surface. The other 90% remains underground.
Thermal features at Mammoth hot springs are always changing. Activity moves from place to place and active terraces grow quickly. Dead trees mark areas that were once vegetated before the springs moved on to it. Some features dry up while others appear or reactivate. Even with these changes the overall activity of the entire area and the volume of water discharge remain relatively constant.
For Looking Close on Friday theme 'Eggs in Black and White'.
While preparing for this theme I knew I wanted a white egg for playing with some white-on-white minimalism. As all the eggs from the local supermarket are brown, I called in at my neighbour's croft where she keeps a few free-range chickens and ducks of various varieties. She very kindly gave me a few eggs that were too small to be sold, from some young hens that had just started laying.
No snails were harmed in the making of this photograph. This snail wasn't in the least bothered by the broken edge of the shell. Some gardeners claim that putting broken eggshells around plants acts as a snail deterrent, but a study done by the Royal Horticultural Society found this to be of no use. Snails may be soft but they are tough!
In fact, eggshells are an excellent source of calcium carbonate that snails need to grow their own shells, so snails may actually be attracted to the broken eggshells for a nutritious nibble. Hence the title of the image is from an old British Egg Marketing Board advertising slogan from the 1960's.
If you don't find it too disgusting, zoom in on the image for the details on the snail's face.
The terraces at Canary Springs are perched on the edge of a hill. These terraces, composed of calcium carbonate (travertine), are part of Mammoth Hot Spring in Yellowstone National Park. Terraces that have active water flow are covered by orange, yellows and cream colored thermophilic organisms like cynobacteria and bacteria. The water for the hot springs comes from precipitation in the surrounding mountains that runs down into the subsurface. The water is heated at depth. As the water rises it dissolves limestone in the subsurface beneath Mammoth and the surrounding mountains. The hot carbonate rich water comes to the surface and forms the travertine terraces. Geologists estimate that at any given time about 10% of the water in Mammoth Hot Springs is on the surface. The other 90% remains underground.
This unusual geologic feature along the Jemez Mountain Trail is about 7,000 years old. The dam is primarily composed of calcium carbonate and travertine. It extends more than 300 feet in length across the Jemez River Valley. In addition, the Soda Dam is 50 feet in height and 50 feet wide at the bottom. Where the river flows through the dam, it creates a unique natural soda bridge over the stream and a scenic waterfall.
Happy Waterfall Wednesday! Take care and stay safe.
Thanks for stopping by and for all of your support -- I deeply appreciate it.

Bellezza mortale - Incredibile lago salato negli altipiani meridionali della Bolivia. Non lasciatevi ingannare dallo splendido colore delle sue acque: è dovuto ai sedimenti di arsenico, rame , piombo e carbonato di calcio. Non ho visto alcuna forma di vita qui. Ma non diamo la colpa all'uomo: è tutta opera della natura che qui è assolutamente incontaminata!

Calcium carbonate deposits at the famous Pamukkale site in Denizli, Turkey. The following quote is from the Interesting Engineering website. Interestingengineering.com
"The Pamukkale and the Hierapolis, an ancient city, were both recognized as a part of the UNESCO World Heritage Sites in 1988. For locals, it is also the 8th Wonder of the World. The name Pamukkale means 'Cotton Castle' in Turkish. Besides its adorable beauty, it is a geological formation which is based on 17 main hot water springs that are actually sources of the calcium carbonate which gets deposited as mineral rock on the surface."
Some of the pools that were formed by the springs are now drying up. The spring water instead is being diverted to the nearby towns to furnish water for the hotels, restaurants, and other tourist accommodations. It is creating quite a bit of controversy in the process because Pamukkale and Hierapolis are said to have been favorite haunts of Cleopatra.

"The growth of drug-related crime is a far greater evil to society as a whole than drug taking. Even so, because we have been seduced by the idea that governments should legislate for our own good, very few people can see how dangerously absurd the present policy is." (John Casey)

This is an image of a tufa formation at South Tufa on Mono Lake on a winter day. For those unaware, these towers are formed when subterranean fresh water springs enter highly alkaline salt water lakes (AKA “soda lakes”) . This causes a reaction with calcium and carbonate salts that forms insoluble calcium carbonate (limestone). This precipitates out and, over time, settles to form large deposits around the location of the springs.
On this day quite a bit of fog had formed on the lake in the cool morning air. It had already started to lift by the time I arrived near mid-day but it still made the background somewhat moody and helped to accentuate the wonderful formations. I shot this image with as long of a shutter opening as I could get away with to smooth the water out as best I could to accentuate that “mirror” look on the water. I also like the way the foreground formation sort of frames the smaller one in the distance.

"tufa towers" are calcium-carbonate spires and knobs formed by interaction of freshwater springs and alkaline lake water. Mono Lake is a majestic body of water covering about 65 square miles. It is an ancient lake, over 1 million years old -- one of the oldest lakes in North America. It has no outlet.
Throughout its long existence, salts and minerals have washed into the lake from Eastern Sierra streams. Freshwater evaporating from the lake each year has left the salts and minerals behind so that the lake is now about 2 1/2 times as salty as the ocean and very alkaline.

"The unusual rock formations that grace Mono Lake's shores are known to geologists as tufa (too'-fah). Tufa forms in a variety of ways at Mono Lake, but the most visible and remarkable formations are the towers that grace Mono's shoreline. The greatest concentration of these towers is located at the South Tufa grove just off of Hwy 120 East, at the south end of Mono Lake. Tufa is essentially common limestone. What is uncommon about this limestone is the way it forms. Typically, underwater springs rich in calcium (the stuff in your bones) mix with lakewater rich in carbonates (the stuff in baking soda). As the calcium comes in contact with carbonates in the lake, a chemical reaction occurs resulting in calcium carbonate--limestone. The calcium carbonate precipitates (settles out of solution as a solid) around the spring, and over the course of decades to centuries, a tufa tower will grow. Tufa towers grow exclusively underwater, and some grow to heights of over 30 feet. The reason visitors see so much tufa around Mono Lake today is because the lake level fell dramatically after water diversions began in 1941." Source: monolake.org

On this day quite a bit of fog had formed on the lake in the cool morning air. It had already started to lift by the time I arrived near mid day but it still made the background somewhat moody. I took a bit of “artistic license” on most of my photos and used a neutral density filter which allowed me to slow my shutter way down. While there wasn’t a great deal of ripple on the water anyway, the longer exposure time removed what little there was and enhanced that “mirror” look.
