Traditionally in Cantabria this range has been considered the border between La Marina (The Coast) and La Montaña (The Mountain).

The Sierra del Escudo de Cabuérniga runs parallel to the coast, separated 15–20 km from it. The altitude of its summits averages between 600 and 1,000 meters above sea level.

The range is broken in several places by gorges eroded by the rivers which flow perpendicularly from the Cantabrian Mountains into the sea. Its continuity is very well marked in the western zone of Cantabria, while to the east, its orography starts to dilute, although the appearance of great faults mark its East-West route. The Escudo River has its sources in this range.^[2]

Geologically the Sierra del Escudo de Cabuérniga is an inverted basin geological fault where Paleozoico stands exposed, along with Mesozoic rocks of the Jurassic and Cretacean periods.^[3]

787.02 hectares of the central strip of the range, near Carmona, are catalogued as a Site of Community Importance.^[4]
