On low ground near the Tâmega, the Archaeological Survey describes accumulations of sand and clay associated with some of the lowland fields offering the greatest farming potential. The contrast is clear: large granite outcrops dominate the slopes; beside the river, deposited materials help explain another way of farming. The same introduction shows hills descending southwards, with waterways seeking the Tâmega and its tributaries. It is not a soil map of each field, but a key to reading the whole landscape.
