I've got a lot of different salt polygon pictures from Death Valley! Here's one taken before sunrise, with the crescent moon setting behind the Amargosa Range. The colors here are good, but about 10 minutes after this shot, the colors were amazing (I'll post the picture within the next several weeks). These were the best polygons I could find anywhere in the valley, even after extensive searching. Before the trip, I naively assumed that the salt polygons were easy to find year-round, because of the abundance of pictures around the internet. Wrong! Apparently recent rains destroyed the easily-accessible shapes. I hiked around Badwater Basin and also down to Cottonball Basin, with no luck (these were the 2 spots that most people indicated for salt shapes). My last shot was to explore north of the West Side Road, and with some serendipity I happened across these polygons!
Death Valley itself is really amazing. The bedrock beneath the Amargosa and Panamint Mountains folds beneath the basin, and over time thousands of feet of sediment has collected. The use of gravimeters has shown that the bedrock is more than 9000 ft beneath Badwater Basin, with layers of salt, silt, clay, and dirt filling up the space. Death Valley is actually a basin - water comes in, but doesn't exit; thus, huge amounts of sediments collect here.
Interesting patterns are reminiscent of the salt polygons in Badwater Basin. Perhaps they're formed in a similar way?
The Saar Polygon in Ensdorf, Saarland is a monument commemorating the coal mining industry in Saarland, which ended in June 2012.

I also used permanent markers and ball-point pens.

Thank you, everyone, for views, faves and comments.
Polygons are of great interest because they often indicate the presence of shallow ice or of desiccation such as in a mud flat. However, Nature sometimes seems too clever for us.
Polygons form by the intersecting ridges of sand dunes. If this deposit were to become indurated and eroded, we might not be able to tell that they originated as wind-blown dunes, and interpret the polygons as evidence for a dried-up lake, for example. Dunes often accumulate in the bottoms on craters, also a good setting for a (temporary) lake.
The illumination is coming from the upper left, so the bluish ridges are high-standing.

The reticulated giraffe (Giraffa camelopardalis reticulata), also known as the Somali giraffe, is a subspecies of giraffe native to Somalia, southern Ethiopia, and northern Kenya. Reticulated giraffes can interbreed with other giraffe subspecies in captivity or if they come into contact with populations of other subspecies in the wild.
The reticulated giraffe is among the most well-known of the nine giraffe subspecies. Together with the Rothschild giraffe, it is by far the giraffe most commonly seen in zoos. Its coat consists of large, polygonal, liver-colored spots outlined by a network of bright-white lines. The blocks may sometimes appear deep red and may also cover the legs.
The extraordinary height of the Reticulated Giraffe allows them to browse on branches of trees that other hoofed animals cannot reach. This has helped make the Reticulated Giraffe one of the most successful animals of the African savannah. The Reticulated Giraffe feeds mainly on Acacia and Combretum trees, however, it will eat as many as 100 different plants depending on which are available at the time.
The Reticulated Giraffe gets a large amount of water from the dew on the leaves and from the water in the leaves. When it encounters a watering hole, it will drink up to 12 gallons at one time. – Wikipedia
The Comma is a fascinating butterfly. The scalloped edges and cryptic colouring of the wings conceal hibernating adults amongst dead leaves, while the larvae, flecked with brown and white markings, bear close resemblance to bird droppings.
The species has a flexible life cycle, which allows it to capitalize on favourable weather conditions. However, the most remarkable feature of the Comma has been its severe decline in the twentieth century and subsequent comeback. It is now widespread in southern Britain and its range is expanding northwards. butterfly-conservation .org
Das Saarpolygon in Ensdorf (Saar) ist ein Denkmal zur Erinnerung an den im Juni 2012 endgültig beendeten Steinkohlebergbau im Saarrevier.
Das Saarpolygon steht auf der Bergehalde Duhamel in Ensdorf, der Bergehalde des Bergwerks Saar. Diese Halde mit einer Grundfläche von rund 50 Hektar erhebt sich rund 150 Meter über das umliegende Saartal. Auf Grund der exponierten Lage ist das Polygon weithin aus allen Himmelsrichtungen sichtbar.
Das begehbare Denkmal ist rund 30 Meter hoch. Zu dem rund 35 Meter überspannenden Querstück führen von beiden Seiten genau 132 Stufen in 25 Meter Höhe. Die Aussichtsplattform wiegt rund 60 Tonnen. (Wikipedia)

What the opposing angles fail to realize is nothing would be possible without the holding foundation.
This twelve sided barn was built in Mystic Quebec, Canada, by Alexander Wallbridge in 1892. Suspended from the top of the barn's conical ceiling, the original mechanism for rotating a large turntable in the centre of the barn is still in place. The turntable, much like the railroad turntables of days gone by, enabled fully laden wagons to enter the barn and to be rotated to the appropriate storage bay, where they would then be unloaded. The building is now a museum.

Like many Commas, the Gray Comma is best identified with the ventral view which in its case is a cryptic charcoal gray pattern and accounts for the common name. They are very difficult to find when perched on a tree trunk or like this one, gathering nutrients from wet, muddy places. There is a striking difference when they open their wings to present the dorsal view which I also posted this evening and looks like the dorsal view of many of the Comma species.

The church is an early Gothic building, dating from the 13"‘ century, and consists of a hall with a polygonal altar, to the east, and a tower, on the west facade. The enclosure wall, made of river stone, was later added.
Built by the Saxons colonists, the church initially belonged to the Catholic cult, and, from the 16"‘ century, it became a Reformed church.
Badwater in Death Valley with awesome last bits of sunlight kissing the tops of the salt polygons. One of the hottest (in the summer) and lowest (-200 feet below sea level) places on earth. I can just imagine cooking eggs out here in August.... no salt needed :D
Thanks for Looking.
The ice floating just off shore at Bear Lake reminds me of the salt formations at Badwater in Death Valley.
