Chevron (insignia), a V-shaped pattern in insignia, heraldry, flag design, road signs, architecture and construction
Chevron (land form), a wedge-shaped sediment deposit composed of material displaced from the ocean floor onto land by a tsunamiA chevron is a wedge-shaped sediment deposit observed on coastlines around the world. These formations sometimes include tiny fossils from the ocean.
Such formations are generally hypothesised to be created from erosion, glaciers, and other natural phenomena.
The Holocene Impact Research Group hypothesizes that the formations could be caused by tsunamis from meteorite impacts or submarine slides which lift sediment up and carry it hundreds of miles until depositing it on coastlines. This idea is controversial because chevrons are similar to wind-blown landforms found far from the ocean, and because it is unlikely that there have been enough large impacts and landslides to explain the observed chevrons.
Many chevrons can be found in Australia, but others are concentrated around the coastlines of the world. For instance there are chevrons in Hither Hills State Park on Long Island and in Madagascar.The chevron occurs in early art including designs on pottery and rock carvings. Examples can be found approximately 1800 BC in archaeological recovery of pottery designs from the palace of Knossos on Crete in the modern day country of Greece.[1]
[edit] Heraldry
A chevron is one of the ordinaries in heraldry, one of the simple geometrical figures which are the chief images in many arms. It can be subject to a number of modifications. When the ends are cut off in a way that looks like the splintered ends of a broken piece of wood, with an irregular zig-zag pattern, it is called éclaté.[2] When shown as a smaller size than standard, it is a diminutive called a chevronel.
[edit] Origin
The origin seems to be the shape of the rafter of a building.[citation needed] It has been used early in the history of heraldry, especially in Normandy. In Scandinavia the Chevron is known as "spar" and is used on arms since the times of crusades (Example: Arvid Gustavsson Sparre).
The chevron resembles V-shapes including a single bird, a flock of birds, and "graphically, a pubic triangle is most directly rendered as a V," and represented the goddess by 15,000 BCE[3].Lost tomb of Jesus
The Talpiot Tomb.The Talpiot Tomb, which in the Discovery Channel documentary "The Lost Tomb of Jesus" was claimed to be the lost tomb of Jesus, is adorned with a Chevron over the entrance.
Geology
The term chevron has been used to refer to a geologic feature found in coastal regions all over the world. According to an article in The New York Times, chevron is a "enormous wedge-shaped sediment deposit," possibly created by an enormous tsunami after an asteroid impact. However, this idea is very controversial; many scientists believe these features are generated by wind. Similar features, called parabolic dunes, are found on the interior of continents, where they could not be explained by tsunamis. Also, tsunamis usually leave thin sheet-like deposits of sand that do not have the distinct chevron shape.
well that google is simply awesome
IF... it is in THAT "cave", yeah... DIG! If "chevron" is carved on tree or boulder; MY understanding... (STILL incomplete...), is that the upright "PEAK(S)" indicate mountain ridge(s), OR... the downward "thingies' are RAVINE(S)! HA! "Situation-Specific".
