Orientation of intense Z-pinch instabilities from an intense aurora as recorded in antiquity: Western USA

Summary form only given. Based on the compilation and analysis of the order of 100,000 digitally logged petroglyphs, we have identified several dozen general categories of instabilities generally associated with sub-gigaampere Z-pinches as might occur in a very intense aurora. But if prehistory man recorded an aurora in the sky, then petroglyphs must possess a preferred orientation overall. An initial study of the GPS database above shows a definite orientation to the Earth´s south seeking pole in the Western USA. The figure below is typical of all sites, either thousands of glyphs or a single glyph. Generally all have a either a westerly or easterly normal and a preferred southerly tangent. While a substantial number also have northerly components, cliffs and slabs that lack a west-south-east view of the horizon are void of glyphs. Voids occur along the mile-long cliff of 5,000 glyphs where the cliff turns away from south.
