Main purpose of this research is to study lithology, structure and textural properties of volcanic debris flow formation, landslides, slope debris in the structural-active tectonic framework of Mt Ilgaz Area. Ultimate goal is to design sustainable Hazard Reduction Project which will also protect existing spectacular morphology as geological heritage. Xrami earth piles (pillars) are proved to be extra-ordinary geological structures, formed in very thick volcanic debris flow unit. They have specific geometry, morphology and radial distribution in a deep oval shaped closed subsidence environment. Debris Flow is unique example of its kind, having uniform grain distribution texture and lithology. Remote Sensing of multi-spectral ASTER images provided textural data and by selective alteration patterns which used to uncover stratigraphy and obscure structural framework. In order to conserve Piles (pillars) against destructive external agents, essential criteria for geotechnical safety projects were decided in situ. Accepted as Geo-Heritage Site, to be conserved in Geo-Park statue.
