Pages of Earth History in an Exceptional Uniqueness: The Geo-Heritage of the Sila National Park and its Spheroidal Boulders Geosite (Northern Calabria, Italy)

Abstract

The knowledge of the territory that people inhabit, the awareness of the geological heritage value and its management are aimed both at the benefit of local socio-economic sustainable development goals and at promoting geopark-inclined geotourism through actions which identify potential geosites or enhance those already assessed. The objective of this study is focused on the geoheritage exploration of the Sila massif area, in southern Italy, in order to illustrate the high “geological diversity” like first step for inherent potential geotourism. The Sila landscape exhibits a rich geodiversity to give value, but it is poorly known to the public, although it has been and is the subject of many national and international scientific works. The focus of this work is to enhance the geological, geomorphological and landscape uniqueness of a Sila area, characterized by the presence of a wide range of weathering products and morphologies as a result of geological and geomorphological events and processes, in a variety of temporal and spatial scales, which have an influence on the development and evolution of reliefs and landscape, giving rise to the three geosites: Sila Spheroidal Boulder Field Geosite, Sila Sand Geosite and Sila Paleosols Geosite. These sites of geological interest were subjected to quantitative assessment in terms of the scientific, educational, touristic values and degradation risk of geosites.
