In this picture, looking towards east, we see the relative location of the snowed Star Mountain, highest mountain range in Portugal (granitic stone and soils), whose springs and winter snow feed the River Mondego, and the southern Colcurinho Peak, that belongs to the Goshawk Mountain range (schist stone and soils). The Colcurinho peak has several springs that feed by gravity the irrigation channels and tanks a few meters above Chão Sobral, which are now under renovation, as we see below.
