Colla Firth

Colla Firth is shown as a bay on the public map of Shetland Islands. The saved point is the map point or the centre of its mapped shape.

Colla Firth is a coastal bay in the Shetland Islands, characterized by sea cliffs and rocky shores formed primarily from Jurassic sandstones and basalts. These rocks date to around 150–180 million years old, formed through sedimentation and volcanic activity during the breakup of Pangaea, and are notable for their exposure of ancient geological processes in a dynamic coastal setting.
