Ca 14.800 Jahre alte Megalithruinen in Nevada USA gefunden

Wo man es bis heute nicht vermutet hatte, mitten in den USA, hier in Nevada, sind Zivilisationsspuren gefunden aus der Megalithzeit mit Petroglyphen bekannter Art. Wir sehen Strahlenmenschen, Sternzeichen und Linien aller Art. Und die Ruinen sehen aus, als hätte hier die Faust Gottes zugeschlagen und ein großes Strafgericht gehalten.
Diese Art Trümmer, die auch überall auf der Welt in verschieden starker Wucht an Megalithruinen zu erkennen sind, verweisen auf eine Weltkatastrophe, wo offensichtlich die Hersteller alle um ihr Leben kamen oder es danach einen Neuanfang einer neuen Zivilisationsentwicklung gab. Denn erst danach entwickelte sich die Pyramidenära.

MessageToEagle.com – A new discovery reveals that the oldest known petroglyphs in North America, which are cut into several boulders in western Nevada, date to at least 10,500 years ago and perhaps even as far back as 14,800 years ago.
The petroglyphs located at the Winnemucca Lake petroglyph site 35 miles northeast of Reno consist of large, deeply carved grooves and dots forming complex designs on several large limestone boulders that have been known about for decades, said University of Colorado Boulder researcher Larry Benson, who led the new effort.
Although there are no people, animals or handprint symbols depicted, the petroglyph designs include a series of vertical, chain-like symbols and a number of smaller pits deeply incised with a type of hard rock scraper.
Benson and his colleagues used several methods to date the petroglyphs, including determining when the water level the Winnemucca Lake subbasin-which back then was a single body of water connecting the now-dry Winnemucca Lake and the existing Pyramid Lake-reached the specific elevation of 3,960 feet.
The elevation was key to the study because it marked the maximum height the ancient lake system could have reached before it began spilling excess water over Emerson Pass to the north.
When the lake level was at this height, the petroglyph-peppered boulders were submerged and therefore not accessible for carving, said Benson, an adjunct curator of anthropology at the University of Colorado Museum of Natural History.
According to Benson, a white layer of carbonate made of limestone precipitated from the ancient, overflowing Winnemucca Lake had coated some of the petroglyph carvings near the base of the boulders. Previous work by Benson showed the carbonate coating elsewhere in the basin at that elevation had a radiocarbon date of roughly 11,000 years ago.
“Prior to our study, archaeologists had suggested these petroglyphs were extremely old,” said Benson, also an emeritus USGS scientist.
“Whether they turn out to be as old as 14,800 years ago or as recent as 10,500 years ago, they are still the oldest petroglyphs that have been dated in North America.”
While Native American artifacts found in the Lahontan Basin-which encompasses the Winnemucca Lake subbasin-date to the time period of 11,300 to 10,500 years ago, it does not rule out the possibility that the petroglyphs were carved as early as 14,800 years ago, Benson said.
