Ground-penetrating radar was used to map the underlying topography of North Ballachulish Moss. Ground-truthing, in the form of sediment coring and test-pitting, provided corroborative evidence for the peat depths as defined by the radar survey. Trial trenching revealed that a suite of radar anomalies identified during the course of the survey related to a buried prehistoric surface with an associated abundance of wooden stakes and twigs.
