Hundreds of Bronze and Iron Age sites have been unearthed by archaeologists in part of the Highlands.
The £100,000 archaeology project has revealed 300 sites over West Caithness.
The project, funded by Baillie Wind Farm, involved Scotland's first large-scale survey using LiDAR - light detection and ranging - technology.
The equipment can map ancient sites in fine detail and reveals 3D images of their shapes, size and content.
As part of the project a cluster of seven Neolithic cairns will be unveiled to the public for the first time.
