Everything changes... This may be one of the hardest lessons of life for beings who, by nature, resist change. In the virtual world, where people, places and things come and go in the blink of an eye, permanence truly is a fleeting concept.

 

The mighty light at Black Basalt Beach shines no more. For more than three years it stood tall as the distinctive landmark of one of Second Life's most beautiful and best loved places. Gone but not forgotten, the lost sims of SL live on in our hearts and minds. Like all things wonderful, the impact these places had on us becomes part of who we are. Few places in the virtual world have had as big an impact on as many residents as Black Basalt, and for this we should all be grateful and strive to carry this tradition forward, for it is what makes Second Life truly unique and special.

 

Thank you Rose, for the things you do in all the wonderful ways you do. ♥

 

Feel it... ♫♪♫

River Skjálfandafljót, the fourth longest river of Iceland, runs within a wonderful canyon, often formed from columnar basalt. Here we see the river right after forming Godafoss waterfall as it continues its flow along the river canyon.

Black Basalt Beach closes tomorrow October 16th .

There is a time in life that change can be good ...it can open new doors all you have to do is take a step forward.

Listen and Feel it

 

Last day: Black Basalt Beach

  

Basalt Collumns along the Iceland coast near Vik.

Columnar jointed volcanics basalt rocks in Qeqertarsuaq, Disko Island, West Greenland.

Basalt is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of Venus, which cover ~80% of the surface, are basaltic; the lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars.

Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flows that can spread over great areas before cooling and solidifying. Flood basalts are thick sequences of many such flows that can cover hundreds of thousands of square kilometres and constitute the most voluminous of all volcanic formations.

Basaltic magmas within Earth are thought to originate from the upper mantle. The chemistry of basalts thus provides clues to processes deep in Earth's interio.

Cruising along the basalt cliffs above Crater Lake between Trinidad and Quincy, Washington, is an eastbound BNSF Z train on the afternoon of September 21, 2016. The train is climbing a grade out of the Columbia River Valley and has just finished working through Trinidad Loop.

Santiago Island has the biggest and longest lava flow, which is located in Sullivan Bay. Geologically speaking, this island is one of the most beautiful and unbelievable formations. The vast basaltic landscape performs smooth and unbroken surfaces with undulations and nods formed by the fluid lava that created the sculpture. It is located on the central west of the archipelago and is formed by two overlapping volcanoes. It is the 4th biggest of the Galapagos archipelago.

A morning photo of The Frying Pan River in Basalt, Colorado.

The Giants causeway in County Antrim on the North coast of N.Ireland is a spectacular sight to behold always amazed to see it every time I go up to this World Heritage Site

A short walk from the coffee shop takes you to this view. Our city is built on an extinct volcano and in places the old lava flows are revealed. The rock is hard and the sea has taken millions of years to make two small caves.

Located on the Snaefellsnes peninsula, the small hamlet of Arnarstapi is the gateway to the magnificent Snaefellsnesjökull National Park. It's also an ideal place to watch the thousands of birds that live and nest on the impressive coastal cliffs that make up one of Iceland's most beautiful landscapes.

Basalt formations near Mt. Baker. This was taken with a 25 second exposure by the light of the moon. Finding the right focus was a challenge. There was not enough light for autofocus and not enough light for me to see clearly for manual focus. I shot a dozen and hoped for the best. The rest were deleted due to the focus issue.

In the morning before we drove to Dyrholaey, where we photographed some puffins like the one in my last upload, we wanted to visit the famous black sand beach Reynisfjara with its famous sea stacks and basalt columns. Originally, we thought about getting there to sunrise, but being a bit worn out from our rush through all the sights in the south the previous days, we woke up a little late and decided to have some breakfast since we already missed the sunrise. However, we didn’t want to leave too late as we knew that busses full of people would probably arrive there soon. So we drove to the black sand beach our navigation system suggested, but this was the beach in Vík from which one can also see the famous sea stacks, but not the basalt columns we wanted to photograph, which were a 15-minute drive away around the corner of the huge cliff.

 

Fortunately, when we arrived at the Reynisfjara parking lot, we were early enough to find a parking spot right away, but there were already quite a few people there (and the buses arrived half an hour later). We first took some images of the famous basalt columns, including some pictures with ourselves in the frame to show the scale, and then walked along the beach towards the famous sea stacks. I really wanted to take some of the classic pictures, but the weather was once again - untypical for Iceland - beautiful with blue skies and harsh sunlight. So we continued our walk and noticed a large basalt column rock formation in front of the cliff. Most of the people were taking pictures of the beach or the cave, but we were both so fascinated by these basalt columns that we spent most of our time trying to find appealing compositions of these rock formations. This image turned out to be one of my favorites because it is very simple, has some nice textures that go pretty well with the dark editing I applied. Funnily enough, not too long ago we watched a video of Micheal Shainblum, who was also recently in Iceland, and it turns out that he shot quite a few images of exactly the same rock formation we also photographed. Even though I’m no Michael Shainblum, I really hope that you like my attempt at capturing this amazing rock formations! :)

Columnar basalt forms a cliff in the stack of volcanic flows that make up the mountains along the southeastern Mosfellsdalur (Mosfell Valley) in Iceland. These hexagonal columns are bounded by cracks or joints that form during the cooling of a thick basalt flow. Geologist refer to them as cooling joints or columnar joints. Though common in basalt, columnar jointing may occur in many types of volcanic flows as they cool and contract.

Pāhoehoe (on the left) is basaltic lava that has a smooth, billowy, undulating, or ropy surface. These surface features are due to the movement of very fluid lava under a congealing surface crust.

 

ʻAʻā (on the right) is basaltic lava characterized by a rough or rubbly surface composed of broken lava blocks called clinker. The clinkery surface actually covers a massive dense core, which is the most active part of the flow. As pasty lava in the core travels downslope, the clinkers are carried along at the surface.

 

The Hawaiian words were introduced as technical terms in geology by Clarence Dutton, who was head of the division of volcanic geology at the United States Geological Survey in the 1880's.

 

I can confirm from personal experience that it is quite easy to walk on pāhoehoe, but the loose, broken, and sharp, spiny surface of an ʻaʻā flow makes hiking difficult, slow and very hard on both feet and shoes.

 

I hope your week ahead has more pāhoehoe than ʻaʻā. Thanks, as always, for stopping by and for all of your kind comments -- I appreciate them all.

Formed by volcanic action, these amazing Basalt Columns rise up to the sky. They are so perfectly formed and fascinating to see. Porto Santo, Portugal

Steps from basalt chunks (here a field stone) over crushed stone and gravel to basalt powder. Paving stones are laid on gravel, then fine gravel and the joints are filled with the finest grade of basalt flour.

At 2500 km², the Vogelsberg is the largest contiguous volcanic area in Central Europe. There are large basalt quarries here.

Der Vogelsberg ist mit 2500 km² das größte zusammenhängende Vulkangebiet Mitteleuropas. Es gibt hier große Basaltsteinbrüche.

Over a period of 20 million years, giant fissures would split open the earth in eastern Washington, time after time spewing molten lava over tens of thousands of square miles, creating multiple layers of now dried and cracked basalt rock. So many layers that, in some places, there are over 10,000 feet of them. Each layer is about 75 to 100 feet thick, a few of which can be seen above near the Potholes Reservoir. These lava beds extend over eastern Washington between 3 rivers, the Spokane, Columbia and the Snake, and into parts of Idaho and Oregon. Then, about 10,000 years ago, at the end of the last ice age, huge lakes of melt water were dammed up by arms of a glacier, which eventually melted, and this huge amount of water roared over the basalt beds, carving, tearing and gouging as it went, creating the Channeled Scablands visible today. The geology of eastern Washington is unique and well worth studying, and even better, visiting in person!

Inspiring vistas abound at Black Basalt Beach. A paradise for anyone longing for the beautiful places of SL.
