and greywackes dominate the landscape, also with granite presence. During the Last Glacial a plateau ice-field and five radiating valley glaciers occupied the highest parts of the mountain with an estimated equilibrium line altitude at 1,650 m asl. The plateau style of the glaciation and the Equilibrium Line Altitude just below the plateau edge made the Estrela very sensitive to climate fluctuations, having resulted in several terminal moraine complexes that reveal several glacial stages. The central plateau area shows widespread glacial erosion features and an almost complete stripping of the Cenozoic weathering mantle.
The non-glaciated plateaus show a rich landscape dominated by granite weathering landforms. The remarkable glacial landscape of the Serra da Estrela when considering its setting in SW Europe, together with other significant geoheritage such as periglacial, weathering and mass wasting phenomena, tectonic, petrological and hydrogeological features, are at the core of Estrela's application to become a UNESCO Global Geopark. But the framework of the application encompasses both the natural and the human landscape, involving nine municipalities in the wider Estrela range, whose population bears an Estrelean signature in its roots, traditions, culture and economy.
The Estrela Aspiring Geopark builds on a high value geoheritage closely bonded with biodiversity and the local communities, and its strategy aims at conservation and promoting regional development in an interdisciplinary approach committed UNESCO's principles.
A field trip to the Estrela Aspiring Geopark will be organized on June 17, 2019, with the support of Associação Geopark Estrela.
The Serra da Estrela (1,993 m asl) is the highest mountain range in mainland Portugal. Bounded by two main fault scarps, a granite massif occupies the central area forming a summit plateau between ci. 1,500 and 2,000 m. To the north and south, schists and
