It is the principal peak within the Snowdonia mountain range, located in Gwynedd county. The mountain is characterized by several peaks connected by sharp ridges and is composed of ancient Ordovician slates and porphyries. The landscape has been significantly shaped by glaciation, resulting in cirques and small lakes.
