An archaeoastronomical investigation of Pre-Inca sites along the Rio Grande, in the Casma province of the Ancash Region, Perù. By silvia motta https://www.academia.edu/10642493/An_archaeoastronomical_investigation_of_Pre_Inca_sites_along_the_Rio_Grande_in_the_Casma_province_of_the_Ancash_Region_Per%C3%B9 In this paper we outline the results of an archaeoastronomical analysis of a group of Pre-Inca sites, located along the banks of the Rio Grande, Perù. We recognized at about 40 sites analyzing the high-resolution satellite images from Google Earth Pro. They consist mainly of monumental architectures and platform mounds of which we measured the geodetic azimuth of orientation. Subsequently an appropriate statistical study was carried out in order to infer their distribution function with the aim to perform an appropriate archaeoastronomical analysis. Following the data obtained, we can suggest an astronomical significance of these analyzed sites. ...
