The Pombeiro River, tributary of the Paiva River, appears in this geosite in the form of successive waterfalls over the granite massif of Montemuro - Pombeiro River Waterfall. The geosite is located right above the waterfall, on top of one of the large granite blocks, where small geoforms caused by river erosion can be observed, such as giant lunchboxes.
From the Santa Bárbara viewpoint you get a privileged view of the morphological depression of Varosa, a tributary river of the Douro. When the river meets rocks massifs of the Montemuro Massif dramatically change direction to the north. This is an excellent example of the adaptation of rivers to the existing fracturing in granitic lithologies.
The area identified as geosite develops around the exploration of a geological resource, wolfram and tin, in the middle of the last century. The tungsten deposits are part of a set of tungsten and tin deposits that are distributed from Galicia to Castile (Spain) across northern and central Portugal, and defining the termed “Stano-Wolframitic Province” (Neiva, 1944).
The geosite is an excellent viewpoint overlooking Penedo da Saudade, owned by Arménio dos Santos Vasconcelos (Vasconcelos, 2009), about 5 meters of altitude. The viewpoint has a stairway with an iron structure that allows access to a magnificent view over the southern slope of the Montemuro mountain range, and over the Paiva valley.
It is the highest point of the locally designated Serra de Bigorne, at over 1200 meters in altitude, and is part of the culminating surface of the Serra do Montemuro. Its about It is an excellent example of a rocky dome in the granitic pattern of the study area, fitting into the salient shapes - intermediate scale shapes. This gives an extraordinary panoramic of the surrounding landscape.
It is a granitic form that has grooves, that is, linear grooves developed vertically on the west-facing surface, with no apparent relationship to the structure. The flutes are centimeter to metric forms of detail, related to the final stages of cryptorelevo exhumation (Vieira, 2008).
Geosite of very high geomorphological interest, located approximately 1213 meters above sea level, it is a magnificent observation point of the Serra do Serra landscape. Montemuro, highlighting the Bestança river fracture valley. Positioned in the Montemuro granite, the geosite is located in the central and highest sector of this mountain, integrating its culminating surface.
The geosite develops in the Montemuro granite, next to the 321 National Road that connects the Castro Daire municipalities to Cinfães and near the junction of the road that follows to the locality of Faifa at an altitude of approximately 1100 meters. Among other taffoni that are in the area under study, this was defined by Vieira (2008) as the local where it is most developed and in the most spectacular form.
The geosite is located on a vertical hole, located over the granite of Alva, where most of the mineral water from Termas do Carvalhal is captured. This hole came replace a set of old catchments, consisting of small deposits usually made on granite excavations. The healing properties of these waters are thought to be dating from Roman times however only over the twentieth century began to explore these properties.
